Cancer refers to any one of a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissue. Cancer often has the ability to spread throughout your body.
Cancer is the second-leading cause of death in the United States. But survival rates are improving for many types of cancer, thanks to improvements in cancer screening and cancer treatment.
Signs and symptoms caused by cancer will vary depending on what part of the body is affected.
Some general signs and symptoms associated with, but not specific to, cancer, include:
Lump or area of thickening that can be felt under the skin
Weight changes, including unintended loss or gain Skin changes, such as yellowing, darkening or redness of the skin, sores that won’t heal, or changes to existing moles
Changes in bowel or bladder habits
Persistent cough or trouble breathing
Persistent indigestion or discomfort after eating
Persistent, unexplained muscle or joint pain
Persistent, unexplained fevers or night sweats
Unexplained bleeding or bruising
When to see a doctor
Make an appointment with your doctor if you have any persistent signs or symptoms that concern you.
If you don’t have any signs or symptoms, but are worried about your risk of cancer, discuss your concerns with your doctor. Ask about which cancer screening tests and procedures are appropriate for you.
Cancer is caused by changes (mutations) to the DNA within 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. Errors in the instructions can cause the cell to stop its normal function and may allow a cell to become cancerous.
What do gene mutations do?
A gene mutation can instruct a healthy cell to:
Allow rapid growth. A gene mutation can tell a cell to grow and divide more rapidly. This creates many new cells that all have that same mutation.
Fail to stop uncontrolled cell growth. Normal cells know when to stop growing so that you have just the right number of each type of cell. Cancer cells lose the controls (tumor suppressor genes) that tell them when to stop growing. A mutation in a tumor suppressor gene allows cancer cells to continue growing and accumulating.
Make mistakes when repairing DNA errors. DNA repair genes look for errors in a cell’s DNA and make corrections. A mutation in a DNA repair gene may mean that other errors aren’t corrected, leading cells to become cancerous.
These mutations are the most common ones found in cancer. But many other gene mutations can contribute to causing cancer.
What causes gene mutations?
Gene mutations can occur for several reasons, for instance:
Gene mutations you’re born with. You may be born with a genetic mutation that you inherited from your parents. This type of mutation accounts for a small percentage of cancers.
Gene mutations that occur after birth. Most gene mutations occur after you’re born and aren’t inherited. A number of forces can cause gene mutations, such as smoking, radiation, viruses, cancer-causing chemicals (carcinogens), obesity, hormones, chronic inflammation and a lack of exercise.
Gene mutations occur frequently during normal cell growth. However, cells contain a mechanism that recognizes when a mistake occurs and repairs the mistake. Occasionally, a mistake is missed. This could cause a cell to become cancerous.
How do gene mutations interact with each other?
The gene mutations you’re born with and those that you acquire throughout your life work together to cause cancer.
For instance, if you’ve inherited a genetic mutation that predisposes you to cancer, that doesn’t mean you’re certain to get cancer. Instead, you may need one or more other gene mutations to cause cancer. Your inherited gene mutation could make you more likely than other people to develop cancer when exposed to a certain cancer-causing substance.
It’s not clear just how many mutations must accumulate for cancer to form. It’s likely that this varies among cancer types.
While doctors have an idea of what may increase your risk of cancer, the majority of cancers occur in people who don’t have any known risk factors. Factors known to increase your risk of cancer include:
Cancer can take decades to develop. That’s why most people diagnosed with cancer are 65 or older. While it’s more common in older adults, cancer isn’t exclusively an adult disease — cancer can be diagnosed at any age.
Certain lifestyle choices are known to increase your risk of cancer. Smoking, drinking more than one alcoholic drink a day (for women of all ages and men older than age 65) or two drinks a day (for men age 65 and younger), excessive exposure to the sun or frequent blistering sunburns, being obese, and having unsafe sex can contribute to cancer.
You can change these habits to lower your risk of cancer — though some habits are easier to change than others.
Your family history
Only a small portion of cancers are due to an inherited condition. If cancer is common in your family, it’s possible that mutations are being passed from one generation to the next. You might be a candidate for genetic testing to see whether you have inherited mutations that might increase your risk of certain cancers. Keep in mind that having an inherited genetic mutation doesn’t necessarily mean you’ll get cancer.
Your health conditions
Some chronic health conditions, such as ulcerative colitis, can markedly increase your risk of developing certain cancers. Talk to your doctor about your risk.
The environment around you may contain harmful chemicals that can increase your risk of cancer. Even if you don’t smoke, you might inhale 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, also are associated with an increased risk of cancer.
Cancer and its treatment can cause several complications, including:
Pain. Pain can be caused by cancer or by cancer treatment, though not all cancer is painful. Medications and other approaches can effectively treat cancer-related pain.
Fatigue. Fatigue in people with cancer has many causes, but it can often be managed. Fatigue associated with chemotherapy or radiation therapy treatments is common, but it’s usually temporary.
Difficulty breathing. Cancer or cancer treatment may cause a feeling of being short of breath. Treatments may bring relief.
Nausea. Certain cancers and cancer treatments can cause nausea. Your doctor can sometimes predict if your treatment is likely to cause nausea. Medications and other treatments may help you prevent or decrease nausea.
Diarrhea or constipation. Cancer and cancer treatment can affect your bowels and cause diarrhea or constipation.
Weight loss. Cancer and cancer treatment may cause weight loss. Cancer steals food from normal cells and deprives them of nutrients. This is often not affected by how many calories or what kind of food is eaten; it’s difficult to treat. In most cases, using artificial nutrition through tubes into the stomach or vein does not help change the weight loss.
Chemical changes in your body. Cancer can upset the normal chemical balance in your body and increase your risk of serious complications. Signs and symptoms of chemical imbalances might include excessive thirst, frequent urination, constipation and confusion.
Brain and nervous system problems. Cancer can press on nearby nerves and cause pain and loss of function of one part of your body. Cancer that involves the brain can cause headaches and stroke-like signs and symptoms, such as weakness on one side of your body.
Unusual immune system reactions to cancer. In some cases the body’s immune system may react to the presence of cancer by attacking healthy cells. Called paraneoplastic syndrome, these very rare reactions can lead to a variety of signs and symptoms, such as difficulty walking and seizures.
Cancer that spreads. As cancer advances, it may spread (metastasize) to other parts of the body. Where cancer spreads depends on the type of cancer.
Cancer that returns. Cancer survivors have a 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 scans and exams in the months and years after your treatment, to look for cancer recurrence.
Start by seeing your family doctor or a general practitioner if you have any signs or symptoms that worry you. If your doctor determines you have cancer, you’ll likely be referred to one or more specialists, such as:
Doctors who treat cancer (oncologists)
Doctors who treat cancer with radiation (radiation oncologists)
Doctors who treat diseases of the blood and blood-forming tissues (hematologists)
Because appointments can be brief, and because there’s often a lot of ground to cover, it’s a good idea to be well-prepared. Here’s some information to help you get ready, and know what to expect from your doctor.
What you can do
Be aware of any pre-appointment restrictions. At the time you make the appointment, be sure to ask if there’s anything you need to do in advance, such as restrict your diet.
Write down any symptoms you’re experiencing, including any that may seem unrelated to the reason for which you scheduled the appointment.
Write down key personal information, including any major stresses or recent life changes.
Write down your family’s history of cancer. If other members of your family have been diagnosed with cancer, make a note of the types of cancer, how each person is related to you and how old each person was when diagnosed.
Make a list of all medications, vitamins or supplements that you’re taking.
Consider taking a family member or friend along. Sometimes it can be difficult to remember all the information provided during an appointment. Someone who accompanies you may remember something that you missed or forgot.
Write down questions to ask your doctor.
Your time with your doctor is limited, so preparing a list of questions can help you make the most of your time together. List your questions from most important to least important in case time runs out. For cancer, some basic questions to ask your doctor 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?
If my cancer can’t be cured, what can I expect from treatment?
What are the potential side effects of each treatment?
Is there one treatment you feel is best for me?
How soon do I need to begin treatment?
How will treatment affect my daily life?
Can I continue working during treatment?
Are there any clinical trials or experimental treatments available to me?
I have these other health conditions. How can I manage them during my cancer treatment?
Are there any restrictions that I need to follow?
Should I see a specialist? What will that cost, and will my insurance cover it?
Is there a generic alternative to the medicine you’re prescribing?
Are there brochures or other printed material that I can take with me? What websites do you recommend?
What will determine whether I should plan for follow-up visits?
In addition to the questions that you’ve prepared to ask your doctor, don’t hesitate to ask other questions that occur to you.
What to expect from your doctor
Your doctor is likely to ask you a number of questions. Being ready to answer them may allow time later to cover other points you want to address. Your doctor may ask:
When did you first begin experiencing symptoms?
Have your symptoms been continuous or occasional?
How severe are your symptoms?
What, if anything, seems to improve your symptoms?
What, if anything, appears to worsen your symptoms?
Does anyone in your family have cancer?
Have you ever had cancer before? If so, what kind 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 infection or a human papillomavirus infection?
Diagnosing cancer at its earliest stages often provides the best chance for a cure. With this in mind, talk with your doctor about what types of cancer screening may be appropriate for you.
For a few cancers, studies show screening tests can save lives by diagnosing cancer early. For other cancers, screening tests are recommended only for people with increased risk.
A variety of medical organizations and patient-advocacy groups have recommendations and guidelines for cancer screening. Review the various guidelines with your doctor and together you can determine what’s best for you based on your own risk factors for cancer.
Your doctor may use one or more approaches to diagnose cancer:
Physical exam. Your doctor may feel areas of your body for lumps that may indicate a tumor. During a physical exam, he or she may look for abnormalities, such as changes in skin color or enlargement of an organ, that may indicate the presence of cancer.
Laboratory tests. Laboratory tests, such as urine and blood tests, may help your doctor identify abnormalities that can be caused by cancer. For instance, in people with leukemia, a common blood test called complete blood count may reveal an unusual number or type of white blood cells.
Imaging tests. Imaging tests allow your doctor to examine your bones and internal organs in a noninvasive way. Imaging tests used in diagnosing cancer may include a computerized tomography (CT) scan, bone scan, magnetic resonance imaging (MRI), positron emission tomography (PET) scan, ultrasound and X-ray, among others.
Biopsy. During a biopsy, your doctor collects a sample of cells for testing in the laboratory. There are several ways of collecting a sample. Which biopsy procedure is right for you depends on your type of cancer and its location. In most cases, a biopsy is the only way to definitively diagnose cancer.
In the laboratory, doctors look at cell samples under the microscope. Normal cells look uniform, with similar sizes and orderly organization. Cancer cells look less orderly, with varying sizes and without apparent organization.
Once cancer is diagnosed, your doctor will work to determine the extent (stage) of your cancer. Your doctor uses your cancer’s stage to determine your treatment options and your chances for a cure.
Staging tests and procedures may include imaging tests, such as bone scans or X-rays, to see if cancer has spread to other parts of the body.
Cancer stages are generally indicated by Roman numerals — I through IV, with higher numerals indicating more advanced cancer. In some cases, cancer stage is indicated using letters or words.
Many cancer treatments are available. Your treatment options will depend on several factors, such as the type and stage of your cancer, your general health, and your preferences. Together you and your doctor can weigh the benefits and risks of each cancer treatment to determine which is best for you.
Goals of cancer treatment
Cancer treatments have different objectives, such as:
Cure. The goal of treatment is to achieve a cure for your cancer, allowing you to live a normal life span. This may or may not be possible, depending on your specific situation.
Primary treatment. The goal of a primary treatment is to completely remove the cancer from your body or kill the cancer cells.
Any cancer treatment can be used as a primary treatment, but the most common primary cancer treatment for the most common 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 kill any cancer cells that may remain after primary treatment in order to reduce the chance that the cancer will recur.
Any cancer treatment can be used as an adjuvant therapy. Common adjuvant therapies include chemotherapy, radiation therapy and hormone therapy.
Palliative treatment. Palliative treatments may help relieve side effects of treatment or signs and symptoms caused by cancer itself. Surgery, radiation, chemotherapy and hormone therapy can all be used to relieve signs and symptoms. Medications may relieve symptoms such as pain and shortness of breath.
Palliative treatment can be used at the same time as other treatments intended to cure your cancer.
Doctors have many tools when it comes to treating cancer. Cancer treatment options include:
Surgery. The goal of surgery is to remove the cancer or as much of the cancer as possible.
Chemotherapy. Chemotherapy uses drugs to kill cancer cells.
Radiation therapy. Radiation therapy uses high-powered energy beams, such as X-rays, to kill cancer cells. Radiation treatment can come from a machine outside your body (external beam radiation), or it can be placed inside your body (brachytherapy).
Stem cell transplant. Stem cell transplant is also known as bone marrow transplant. Your bone marrow is the material inside your bones that makes blood cells from blood stem cells. A stem cell transplant can use your own stem cells or stem cells from a donor.
A stem cell transplant allows your doctor to use higher doses of chemotherapy to treat your cancer. It may also be used to replace diseased bone marrow.
Immunotherapy. Immunotherapy, also known as biological therapy, uses your body’s immune system to fight cancer. Cancer can survive unchecked 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. Some types of cancer are fueled by your body’s hormones. Examples include breast cancer and prostate cancer. Removing those hormones from the body or blocking their effects may cause the cancer cells to stop growing.
Targeted drug therapy. Targeted drug treatment focuses on specific abnormalities within cancer cells that allow them to survive.
Clinical trials. Clinical trials are studies to investigate new ways of treating cancer. Thousands of cancer clinical trials are underway.
Other treatments may be available to you, depending on your type of cancer.
No alternative cancer treatments have been proved to cure cancer. But alternative medicine options may help you cope with side effects of cancer and cancer treatment, such as fatigue, nausea and pain.
Talk with your doctor about what alternative medicine options may offer some benefit. He or she can also discuss whether these therapies are safe for you or whether they may interfere with your cancer treatment.
Some alternative medicine options found to be helpful for people with cancer include:
A cancer diagnosis can change your life forever. Each person finds his or her own way of coping with the emotional and physical changes cancer brings. But when you’re first diagnosed with cancer, sometimes it’s difficult to know what to do next.
Here are some ideas to help you cope:
Learn enough about cancer to make decisions about your care. Ask your doctor about your cancer, including your treatment options and, if you like, your prognosis. As you learn more about cancer, you may become more confident in making treatment decisions.
Keep friends and family close. Keeping your close relationships strong will help you deal with your cancer. Friends and family can provide the practical support you’ll need, such as helping take care of your house if you’re in the hospital. And they can serve as emotional support when you feel overwhelmed by cancer.
Find someone to talk with. Find a good listener who is willing to listen to you talk about your hopes and fears. This may be a friend or family member. The concern and understanding of a counselor, medical social worker, clergy member or cancer support group also may be helpful.
Ask your doctor about support groups in your area. Other sources of information include the National Cancer Institute and the American Cancer Society.
There’s no certain way to prevent cancer. But doctors have identified several ways of reducing your cancer risk, such as:
Stop smoking. If you smoke, quit. If you don’t smoke, don’t start. Smoking is linked to several types of cancer — not just lung cancer. Stopping now will reduce your risk of cancer in the future.
Avoid excessive sun exposure. Harmful ultraviolet (UV) rays from the sun can increase your risk of skin cancer. Limit your sun exposure by staying in the shade, wearing protective clothing or applying sunscreen.
Eat a healthy diet. Choose a diet rich in fruits and vegetables. Select whole grains and lean proteins.
Exercise most days of the week. Regular exercise is linked to a lower risk of cancer. Aim for at least 30 minutes of exercise 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 may increase your risk of cancer. Work to achieve and maintain a healthy weight through a combination of a healthy diet and regular exercise.
Drink alcohol in moderation, if you choose to drink. If you choose to drink alcohol, limit yourself to one drink a day if you’re a woman of any age or a man older than age 65, or two drinks a day if you’re a man 65 years old or younger.
Schedule cancer screening exams. Talk to your doctor about what types of cancer screening exams are best for you based on your risk factors.
Ask your doctor about immunizations. Certain viruses increase your risk of cancer. Immunizations may 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 against these viruses is appropriate for you.
