Cancer: Causes, Types, Symptoms, Diagnosis and Treatment

What Is Cancer?

Cancer is any disease in which abnormal cells divide uncontrollably and can invade and destroy normal body tissue. Cancer often spreads throughout the body.

Cancer is the second-leading cause of death in the world, but survival rates are improving for many types of cancer thanks to improvements in cancer screening and treatment.

 

Cancer


 

Explanation of medical terms and concepts Cancer 


Cancer could be an illness during which a number of the body’s cells grow uncontrollably and unfold to different components of the body.


Cancer will begin in nearly a place within the anatomy that is created of trillions of cells. Normally, human cells grow and multiply (through a method known as cell division) to create new cells because the body desires them. Once cells grow up or become broken, they die, and new cells take their place.


Sometimes this orderly method breaks down, and abnormal or broken cells grow and multiply after they shouldn’t. These cells could type tumors, that are lumps of tissue. Tumors will be cancerous or not cancerous (benign).


Cancerous tumors unfold into, or invade, close tissues and might travel far off within the body to create new tumors (a method known as metastasis). Cancerous tumors may additionally be known as malignant tumors. several cancers type solid tumors, however cancers of the blood, like leukemias, typically don't.


Benign tumors don't unfold into, or invade, close tissues. Once removed, benign tumors typically don’t grow back, whereas cancerous tumors generally do. Benign tumors will generally be quite giant, however. Some will cause serious symptoms or be life threatening, like benign tumors within the brain.


Experts don’t nevertheless have all the answers concerning what causes cancer. There are, however, bound characteristics—called risk factors—that might increase your chance of developing cancer.

 

You can manage some risk factors (smoking, for example), however not others (like your race or age). Moreover, some cancers are often caused by factors in your atmosphere, like exposure to the ultraviolet (UV) radiation in daylight. And a little range could also be joined to Associate in Nursing initial infection with an endemic or microorganism.

 

Beyond those risk factors, some cancers are transmissible, which means they're passed down through your family. per the yankee Cancer Society, concerning five p.c to ten p.c of all cancers are unit transmissible from factor defects (mutations).

 

In some cases, researchers have found out the precise genes which will cause cancer, and that they will typically give counseling to assist you perceive your risk. However alternative cancers are a unit caused by mutations that happen to a person over time.

 

An important means for you to presumably sight cancer early, once it’s easier to treat, is to bear a cancer screening. Through screenings, doctors check folks that don’t essentially have any cancer symptoms. looking at your age, gender or alternative risk factors, your care team might advocate you get checked for cancers.

Symptoms Cancer

Cancer can cause different signs and symptoms depending on which part of the body is affected.

Some general signs and symptoms that are often associated with cancer, but not specific to it, include:

  • Fatigue

  • You may feel a lump or area of thickening under the skin.

  • Weight changes can include unintentional loss or gain.

  • Skin changes such as a yellowing or darkening of the skin, sores that won't heal, or changes to existing moles are possible signs of sun exposure.

  • Changes in bowel or bladder habits

  • Persistent cough or trouble breathing

  • Difficulty swallowing

  • Hoarseness

  • If you experience indigestion or discomfort a few hours after eating, it might be because of something you ate.

  • If you are experiencing persistent unexplained muscle or joint pain, you may want to see a doctor.

  • If you have fever or night sweats that don't go away, it might be because of an unknown cause.

  • Unexplained bleeding or bruising

When to see a doctor

If you have any persistent signs or symptoms that worry you, make an appointment with your doctor.

If you don't have any symptoms but are concerned about your cancer risk, speak to your doctor. Ask which cancer screenings are appropriate for you and whether any procedures may be needed.

Causes Cancer

Cancer is caused by damage to the DNA inside cells. The DNA inside a cell is packaged into a large number of individual genes each of which contains a set of instructions telling the cell what functions to perform as well as how to grow and divide. If there are errors in the instructions, this can cause cancer. Cell damage can cause a cell to stop functioning normally, which may lead to cancer.

What do gene mutations do?

A gene mutation can cause a healthy cell to do something.

  • Allow rapid growth.A gene mutation can cause a cell to grow faster, which produces many new cells that all have the same mutation.

  • Fail to stop uncontrolled cell growth.Cancer cells don't obey the same rules as normal cells. They don't stop growing when they should, which allows them to grow and become more numerous. Sometimes a mutation in a gene that controls growth occurs, which allows cancer cells to keep growing even when they shouldn't.

  • Making mistakes when repairing DNA errors can be dangerous.DNA repair genes look for mistakes in a cell's DNA and fix them. A mutation in a DNA repair gene may mean that other mistakes aren't corrected, which can lead to cancer.

Cancer is caused by a number of different gene mutations. But many other gene mutations can also contribute to cancer.

What causes gene mutations?

Mutations can happen for a variety of reasons, such as:

  • Gene mutations you're born with.Some cancers are caused by genetic mutations that you inherited from your parents. This is a small percentage of all cancers.

  • Gene mutations that occur after birth.Most gene mutations occur after you are born and cannot be inherited. A number of factors can cause gene mutations, such as smoking, radiation, viruses, cancer-causing chemicals (carcinogens), obesity, hormones, chronic inflammation, and a lack of exercise.

Normal cell growth often results in gene mutations. However, cells have a mechanism that recognizes when a mistake has occurred and repairs it. Occasionally, a mistake is missed, which can lead to cancer.

How do mutations interact with each other?

Cancer is caused by genetic mutations and by things you do during your lifetime, like smoking or being exposed to radiation.

If you have a gene mutation that increases your chance of developing cancer, this does not mean you will get cancer. You may need other gene mutations to make this happen. Cancer can be caused by a certain substance that can cause cancer.

It's not clear exactly how many mutations must accumulate for cancer to form. It's likely that this varies depending on the type of cancer.

Risk factors Cancer

Most cancers occur in people who don't have any known risk factors. Factors that increase your risk of cancer include:

Your age

It can take many years for cancer to develop. That's why most people who are diagnosed with cancer are over 65 years old. While cancer can occur at any age, it is more common in older adults.

Your habits

Some lifestyle choices may increase your risk of developing cancer. Smoking, drinking more than one drink a day, being obese, and having unsafe sex can all contribute to this problem.

There are several things you can do to lower your risk of cancer — though some things are easier to change than others.

Your family history

There are many types of cancer, but not all of them are due to an inherited condition. If you have a family history of cancer, it's possible that mutations are being passed from one generation to the next. You might want to consider genetic testing in order to see if you have inherited these mutations. There is a risk of certain cancers if you have an inherited gene mutation. However, not everyone who inherits a gene mutation will get cancer.

You have health conditions.

Chronic health conditions such as ulcerative colitis can increase your risk of developing certain cancers. Talk to your doctor about your risk for cancer.

Your environment

The environment you live in can contain harmful chemicals that can increase your risk of cancer. Even if you don't smoke, you might be exposed to secondhand smoke if you go where people are smoking or if you live with someone who smokes. Chemicals in your home or workplace, such as asbestos and benzene, can also increase your risk of cancer. Leaves are also associated with an increased risk of cancer.

Complications

Treatment for cancer can cause several complications, including:

  • Pain.Pain can come from cancer or cancer treatment. Treatments such as medications and surgeries can effectively reduce or eliminate cancer-related pain.

  • Fatigue.People with cancer may experience fatigue. This fatigue is common during chemotherapy or radiation therapy treatments, but it usually goes away after a while.

  • Difficulty breathing.Cancer or cancer treatment can cause a feeling of shortness of breath. Treatment may bring relief.

  • Nausea.Some cancers and cancer treatments can cause nausea. Your doctor can sometimes predict if your treatment is likely to cause nausea. There are medications and other treatments that can help you prevent or decrease nausea.

  • Diarrhea or constipation.Cancer and cancer treatments can cause diarrhea or constipation.

  • Weight loss. Cancer and cancer treatment may cause weight loss. Cancer takes food away from normal cells, depriving them of nutrients. This is not usually affected by how many calories or what kind of food is eaten; it is difficult to treat. In most cases, using artificial nutrition through tubes into the stomach helps. Adding a vein to a weight loss plan does not make it more effective.

  • Chemical changes in your body.If cancer causes a change in your body's chemical balance, this can increase your risk of serious complications. Symptoms might include an increased thirst, frequent urination, and constipation.

  • Brain and nervous system problems.Cancer can affect nearby nerves, causing pain and loss of function in one part of your body. When cancer affects the brain, it can cause headaches and signs and symptoms that are similar to a stroke, such as weakness on one side of the body.

  • Some people have unusual immune system reactions to cancer.Sometimes the body's immune system may react to the presence of cancer by attacking healthy cells. This is called a paraneoplastic syndrome, and it can cause a variety of signs and symptoms such as difficulty walking and seizures.

  • Cancer that spreads.Cancer can spread to other parts of the body as it progresses.There is no one answer to this question - it depends on the type of cancer.

  • Cancer that comes back. Cancer survivors have a greater risk of cancer recurrence. Some cancers are more likely to recur than others. Ask your doctor about what you can do to reduce your risk of cancer recurrence. Your doctor may devise a follow-up care plan for you after treatment. This plan may include periodic screening tests and examinations. It is important to monitor your cancer recurrence after treatment.

Prevention Cancer

There are several ways to reduce your risk of cancer, such as:

  • Stop smoking.If you want to avoid cancer, quit smoking. If you don't smoke, you don't have to start now. Smoking is linked to several types of cancer, including lung cancer. Quitting now will reduce your risk of developing cancer in the future.

  • Avoid excessive sun exposure.UV rays from the sun can increase your risk of skin cancer. To reduce your risk, stay in the shade and wear protective clothing when outdoors. Also, apply sunscreen to protect your skin from the sun's harmful UV rays.

  • Eat a healthy diet.Eat a diet that is rich in fruits and vegetables. Include whole grains and lean proteins. Avoid processed meats.

  • Exercise most days of the week.Exercise is linked to a lower risk of cancer. Aim for at least 30 minutes of exercise a day, most days of the week. If you haven't been exercising regularly, start out slowly and work your way up to 30 minutes or longer.

  • Maintain a healthy weight.Being overweight or obese can increase your risk of developing cancer. You can achieve and maintain a healthy weight by following a healthy diet and regular exercise.

  • If you choose to drink alcohol, drink in moderation.If you choose to drink alcohol, do so in moderation. This means up to one drink a day for women and up to two drinks a day for men.

  • Schedule cancer screening exams.Talk to your doctor about which cancer screenings are best for you based on your risk factors.

  • Immunizations are important, so ask your doctor about them. Certain viruses can increase your risk of cancer. Immunizations can help prevent those viruses, including hepatitis B which increases the risk of liver cancer and human papillomavirus (HPV) which increases the risk of cervical cancer and other cancers. Ask your doctor whether immunization is right for you based on your individual risk factors. It is not appropriate for you to have a virus.

Diagnosis Cancer

Cancer screening

Cancer can be diagnosed at its earliest stages if it is caught in time. So talk with your doctor about which cancer screenings are appropriate for you.

For some cancers, screening tests have been shown to save lives by detecting cancer early. For other cancers, screening tests are recommended for people who have an increased risk of developing cancer.

There are many different medical organizations that have recommendations for cancer screening. Talk to your doctor to see what guidelines are best for you based on your personal risk factors for cancer.

Cancer diagnosis

Your doctor may use one or more approaches to diagnose cancer. These approaches could include: - Examining symptoms - Doing a physical exam - Checking for abnormalities in cells - Performing tests

  • Physical exam.Your doctor may feel some areas of your body to see if there are any lumps that could be a sign of cancer. During a physical exam, your doctor may look for anything that is out of the ordinary, such as changes in your skin color or an increase in the size of an organ.

  • Laboratory tests.Tests in a laboratory such as urine and blood can help your doctor identify abnormalities that may be caused by cancer. For instance, in people with leukemia an unusual number or type of white blood cells may be revealed through a blood test called a complete blood count.

  • Imaging tests. An imaging test will allow your doctor to view your bones and internal organs without having to go through surgery. Imaging tests that may be used to diagnose cancer include a computerized tomography (CT) scan, a bone scan, a magnetic resonance imaging (MRI) scan, a positron emission tomography (PET) scan, an ultrasound scan, and an X-ray. There are other people in the world.

  • Biopsy.Your doctor will collect cells from your tumor for testing in the laboratory. There are several ways to do this. The method chosen depends on the type of cancer and where it is located. In most cases, a biopsy is the only way to be sure you have cancer.
    In the laboratory, doctors look at cell samples under a microscope. Normal cells look similar in size and shape, while cancer cells look less orderly and have different sizes and shapes.

Cancer stages

When cancer is diagnosed, your doctor will use the cancer's stage to determine your treatment options and your chances for a cure.

Tests to see if cancer has spread may include imaging tests such as bone scans or X-rays.

Cancer stages are denoted by numbers from 0 to 4. Higher numbers indicate a more advanced cancer. For some cancers, cancer stage is denoted using letters or words.

Goals of cancer treatment

Treatments for cancer have different goals, such as:

  • Cure.Our goal is to cure your cancer so that you can live a normal life span. This may or may not be possible depending on your specific situation.

  • Primary treatment.The goal of primary treatment is to remove the cancer from your body or kill the cancer cells.
    Cancer treatment can be used as a primary treatment for most cancers, but the most common primary cancer treatment for most cancers is surgery. If your cancer is particularly sensitive to radiation therapy or chemotherapy, you may receive one of those therapies as your primary treatment.

  • Adjuvant treatment.The goal of adjuvant therapy is to reduce the chance that cancer will return after primary treatment.
    Any cancer treatment can be used in addition to other treatments. Common adjuvant therapies include chemotherapy, radiation therapy, and hormone therapy.

  • Palliative treatment. Some treatments that are used to relieve side effects or signs and symptoms caused by cancer itself may help. Surgery, radiation therapy, and hormone therapy can all be used to reduce symptoms and slow the growth of the cancer. Medications can also relieve symptoms. The leaves can relieve pain and shortness of breath.
    Treatment to cure your cancer can be done at the same time as palliative treatment, which is intended to provide comfort and relief.

Cancer treatments

Doctors have many ways to treat cancer. Treatment options include:

  • Surgery.The goal of surgery is to remove the cancer or as much of the cancer as possible.

  • Chemotherapy.Chemotherapy is a process that uses drugs to kill cancer cells.

  • Radiation therapy.Radiation therapy is a type of treatment that uses high-powered energy beams to kill cancer cells. It can come from a machine outside your body (external beam radiation) or it can be placed inside your body (brachytherapy).

  • Bone marrow transplant.A bone marrow transplant is also known as a stem cell transplant. Your bone marrow is the material that makes blood cells. You may receive your own cells or cells from a donor.
    A bone marrow transplant allows your doctor to give you higher doses of chemotherapy in order to treat your cancer. It may also be used to replace diseased bone marrow.

  • Immunotherapy.Immunotherapy is a type of cancer treatment that uses your body's immune system to fight the cancer. Cancer can survive in your body because your immune system doesn't recognize it as an intruder. Immunotherapy can help your immune system see the cancer and attack it.

  • Hormone therapy.Cancer can be caused by hormones in your body. For example, breast cancer and prostate cancer are fueled by hormones. Removing or blocking the effects of those hormones may cause the cancer cells to stop growing.

  • Targeted drug therapy.Cancer treatment is focused on specific abnormalities within cancer cells that allow them to survive.

  • Clinical trials.Clinical trials are studies to investigate ways to treat cancer. Thousands of clinical trials are currently underway to find new treatments for cancer.

Depending on your cancer type, other treatments may be available to you.

Alternative medicine

There are no known cancer treatments that have been proven to cure cancer. However, some alternative medicine options may help you deal with the side effects of cancer and cancer treatment such as fatigue, nausea, and pain.

Talk with your doctor about which alternative therapies may offer some benefit. Your doctor can also discuss whether these therapies are safe for you or may interfere with your cancer treatment.

Some alternative medicine options that have been found to be helpful for people with cancer include:

  • Acupuncture

  • Hypnosis

  • Massage

  • Meditation

  • Relaxation techniques

  • Yoga

Coping and support

When you are diagnosed with cancer, your life can change forever. Each person deals with cancer in his or her own way. But when you are first diagnosed, sometimes it is difficult to know what to do next.

Here are some ideas to help you cope:

  • Be knowledgeable about cancer so that you can make informed decisions about your care.Talk to your doctor about your cancer, including the treatment options and your prognosis. As you learn more about cancer, you may feel more confident in making treatment decisions.

  • Keep friends and family close.Having strong relationships will help you deal with your cancer. Friends and family can provide practical support such as helping take care of your house if you're in the hospital. And they can provide emotional support during times when you feel overwhelmed by cancer.

  • Find someone to talk with.Find someone who will listen to you and understand what you are feeling. This could be a friend or family member, a counselor, medical social worker, clergy member, or cancer support group.
    There are many sources of information available, including your doctor and the National Cancer Institute.

Preparing for your appointment

If you have any signs or symptoms that make you worry, see your doctor. If your doctor determines that you have cancer, you may be referred to one or more specialists. These might include a doctor who specializes in cancer treatment, such as an oncologist.

  • Doctors who treat cancer (oncologists)

  • Doctors who treat cancer with radiation (radiation oncologists) are special doctors.

  • Doctors who treat diseases of the blood vessels and blood cells (hematologists)

  • Surgeons

If you have an appointment with your doctor, it is a good idea to be prepared. Here is some information that can help you know what to expect.

What you can do

  • Make sure you are aware of any pre-appointment restrictions.Make sure to ask if there are any special instructions you need to follow before your appointment, such as restricting your diet.

  • Write down any symptoms you are experiencing, such as feeling sick or having a headache.Make sure to bring any materials that may seem unrelated to the reason for which you scheduled the appointment.

  • Write down key personal information,This activity is best done after you have had a break from your stresses and recent life changes.

  • Make a list of your family's history of cancer.If anyone in your family has been diagnosed with cancer, make a note of the type of cancer, how closely related you are to the person with cancer, and when the person was diagnosed.

  • Make a list of all the medications you are taking.What you're taking as vitamins or supplements.

  • It is a good idea to bring someone along who can help you.If you forget something during your appointment, someone who is accompanying you may be able to help you remember what was discussed.

  • Write down questions to ask your doctor.

You will only have a limited amount of time with your doctor, so it is important to have questions prepared in advance. Make a list of the most important questions first, and then add other questions as they occur to you. Some basic questions to ask your doctor about cancer might include:

  • What type of cancer do I have?

  • What stage is my cancer?

  • Will I need additional tests?

  • What are my treatment options?

  • Can treatments cure my cancer?

  • What are the possible side effects of treatment for my cancer?

  • What are the possible side effects of each treatment?

  • Can you tell me what treatment would be best for me?

  • How soon do I need to begin treatment?

  • How will treatment affect my daily life?

  • Can I continue working during treatment?

  • Can I find any clinical trials or experimental treatments that are available to me?

  • I have other health conditions. How can I best manage them while I am undergoing cancer treatment?

  • Are there any guidelines that I should follow?

  • Should I see a doctor? How much will it cost and can my insurance cover it?

  • Can I substitute another medicine for the one you're prescribing?

  • Can I take any printed material with me? What websites do you recommend?

  • What will determine whether I should make follow-up visits?

Don't be afraid to ask questions that occur to you during your appointment.

What to expect from your doctor

Your doctor is likely to ask you a number of questions. Being prepared to answer them may allow time later to address other points you want to discuss. Your doctor may ask:

  • When did you first begin to experience the symptoms?

  • Do you have the same symptoms every time or do they come and go?

  • How severe are your symptoms?

  • What can improve your symptoms?

  • What if anything seems to make your symptoms worse?

  • Does anyone in your family have cancer?

  • Do you have any experience with cancer before? If so, what kind was it and how was it treated?

  • Have you ever been exposed to chemicals at home or at work?

  • Do you smoke or use tobacco?

  • Have you ever been diagnosed with a hepatitis or HPV infection?

What does the future hold for cancer treatment?

The future of cancer treatment lies in providing patients with a good larger level of personalization. Doctors area units commencing to provide treatment choices supported the genetic changes occurring in a very specific tumor.


An innovative new diagnostic tool, the genomic tumor assessment, examines a patient’s tumor genetically to spot the mechanism that caused the cancer. Genomic tumor assessment could lead to a lot of personalized approaches to cancer treatment.

General summary

-Causing Foods To Watch Out For Tuna and Processed Meats The World Health Organization has classified processed meats as a cause of cancer in humans These foods which include bacon and hot dogs contain high levels of nitrates which are associated with increased risk for gastrointestinal cancers Tuna can also contribute to an increased risk for certain types of cancer because it contains methyl mercury a chemical that has been linked to higher rates of several types of tumors

Treatment Cause Hair Loss After learning that she had breast cancer Michele says it was a shock to learn that her hair loss is common among people with cancer “I expected I would have some hair falling out usually from the roots and not a lot at first," she explains " What I did not expect was that within two weeks half of my hair would be gone."

What are new treatments for cancer?

Scientists have made persistent efforts to find new ways of preventing and fighting cancer Among the most recent advances are gene therapies which manipulate DNA to fight cancerous growths There also is a vaccine for lung cancer which uses the body's own immune system to attack tumors New medications are being developed that target tumor-suppressing genes helping to slow or stop the formation of new cancers

Can cancers be cured? Absolutely In fact some forms of cancer are curable by surgical removal of the cancerous cells prior to their transmission throughout the body via blood or lymphatic vessels Sometimes a drug will eliminate cancer cells as well as stop their spread in other tissues that may have become involved It is important to treat cancer quickly to avoid further damage and possible death

How does cancer treatment work?

Cancer is a group of more than 100 diseases each involving cells growing out of control Cancer can affect almost any part of the body and there are different types of cancer When doctors talk about cancer treatment they're referring to ways to stop cancer from growing or spreading The way that people with cancer are treated depends on many factors such as: The stage and type of their cancer; The size of the tumor; Other medical issues; and Whether the patient's wishes come into play when planning treatment options (for example whether he or she wants "palliative care" - care

Is chemotherapy painful?

It depends on the type of cancer type of treatment and the patient While many people have no pain with chemotherapy according to KidsHealth.org some do experience discomfort from side effects such as nausea vomiting and diarrhea The good news is that chemotherapy can be administered in different ways (oral drugs and IV infusions) so options are available to lessen or eliminate side effects

What cancers can be cured?

Researchers now say that 80 percent of all cancers are curable and the latest statistics from cancer.gov indicate a 5-year survival rate for many types of cancer Most of these cures are a result of early detection programs which let people know when disease has penetrated beyond tissues into surrounding tissues or organs Early detection and treatment can be lifesaving even for advanced cancer patients

What cancers have the highest survival rate?

The five cancers with the highest survival rates are all very treatable if detected early enough The National Cancer Institute lists these cancers as breast prostate colon and rectum melanoma of the skin and non-Hodgkin lymphoma

What are the deadliest cancers?

According to a study published in the Journal of Clinical Oncology by two researchers at the National Cancer Institute (NCI) cancers in certain parts of the body have a higher mortality rate than those in other areas Breast cancer is more lethal when it develops near major veins and arteries Pancreatic cancer is more lethal if it spreads within the abdomen And lung cancer has the highest mortality rate among all types of skin cancer according not only to NCI's Dr Richard J Martin but also to the American Cancer Society and Cleveland Clinic which state that "deaths due to this [lung] cancer are mainly caused

What is a high grade tumor?

A high grade tumor is one that is malignant or cancerous It’s typically more aggressive than a low grade tumor and spreads quickly through the body High grade tumors are often harder to treat than low grade tumors because they tend to be resistant to chemotherapeutic agents and radiation treatments However there are some specific high-grade tumors which can be treated with immunotherapy drugs like Yervoy (ipilimumab)
