Breast cancer occurs when abnormal cells grow out of control in the breast. These cancer cells can spread within the breast, to nearby lymph nodes and other tissues, and to other parts of the body.
Being treated for cancer can weaken your body, and you may feel very tired. Get the rest your body needs so you can feel better.
Finding out that you have cancer is scary. You may feel many emotions and may need some help coping. Seek out family, friends, and counselors for support. You also can do things at home to make yourself feel better while you go through treatment. Call the American Cancer Society (1-800-227-2345) or visit its website at www.cancer.org for more information.
Breast cancer happens when cells in your breast grow abnormally and out of control. The cancer cells can spread to other parts of your body.
You're more likely to get breast cancer as you get older.
Breast cancer can occur in anyone.
Often breast cancer is found in an early stage, and the cancer can be removed with surgery. In some cases, breast cancer may grow and spread to nearby tissues and lymph nodes. Advanced breast cancer can spread to the bones, liver, and brain.
Your doctor will look at the stage of the cancer to see how far it has spread. Your doctor may also do tests on tissues removed during surgery to look for hormone receptors and gene changes. These test results, and whether your cancer has spread, will help guide your treatment options.
The most common symptom is a painless lump or thickening in the breast or underarm. But early breast cancer is often found on a mammogram before a lump can be felt. The size, shape, or appearance of the breast may also change. Or the nipple may turn in, look scaly, or leak fluid.
Breast cancer is the growth of abnormal cells in the ducts or lobes of the breast. Breast cancer may be either:
Some breast cancer is a mix of ductal and lobular carcinoma. Other less common invasive types include inflammatory breast cancer and male breast cancer.
After the type of cancer is known, the cancer cells are checked for estrogen receptors, progesterone receptors, and large amounts of a protein called HER2. This information helps a doctor plan the treatment.
If the cancer cells don’t have these three traits, they are called “triple negative.” Triple-negative breast cancer is a less common type of invasive breast cancer.
Treatment for breast cancer is based on the type and stage of the cancer and other things, such as your overall health. The main treatment is surgery to remove the cancer. Other treatment options may include radiation therapy, chemotherapy, endocrine therapy, or targeted therapy.
External beam radiation works well to destroy cancer cells, but it can also harm normal cells. This can lead to side effects.
The most common short-term side effects of radiation therapy for breast cancer are:
Most short-term side effects will go away within a few weeks after you finish treatment. But it may take longer to get your energy back.
Some side effects may occur months or years after radiation therapy. These long-term side effects may include:
Experts know that people who are BRCA-positive are more likely to get breast cancer and ovarian cancer. If you are BRCA-positive, you can take steps to reduce your risk of these cancers.
To help those with BRCA changes, experts did a study of women with BRCA changes to predict how much breast and ovarian cancer risk could be reduced by certain methods. These methods include:
The results of the study are shown in the tables below.
The study also looked at having the surgeries at different ages. For example, you can see what difference it might make if you keep your breasts and ovaries until you're past your childbearing years. These results are one piece of information you can use as you explore how to lower your cancer risk.
Surgery and screening tests are not your only options. You can also talk to your doctor about medicines, such as tamoxifen. Or you may choose to have no treatment or extra screening.
According to the study, here's how the different prevention methods affect the life spans of those with BRCA1 changes.
Prevention method | Those who live to age 70 after this method |
---|---|
No treatment or extra screening. | 53 out of 100 |
Annual breast screening. | 59 out of 100 |
Ovaries removed at age 50. | 61 out of 100 |
Breasts removed at age 40. | 64 out of 100 |
Breasts removed at age 25. | 66 out of 100 |
Ovaries removed at age 40. | 68 out of 100 |
Annual screening + ovaries removed at age 40. | 76 out of 100 |
Annual screening + breasts and ovaries removed at age 40. | 77 out of 100 |
Breasts removed at age 25 + ovaries removed at age 40. | 79 out of 100 |
According to the study, here's how the different prevention methods affect the life spans of those with BRCA2 changes.
Prevention method | Those who live to age 70 after this method |
---|---|
No treatment or extra screening. | 71 out of 100 |
Annual screening. | 75 out of 100 |
Ovaries removed at age 50. | 75 out of 100 |
Ovaries removed at age 40. | 77 out of 100 |
Annual screening + breasts removed at age 40. | 78 out of 100 |
Breasts removed at age 25. | 79 out of 100 |
Annual screening + ovaries removed at age 40. | 81 out of 100 |
Annual screening + breasts and ovaries removed at age 40. | 82 out of 100 |
Breasts removed at age 25 + ovaries removed at age 40. | 83 out of 100 |
Take some time to think about your options. A genetic counselor can help you understand how the prevention options affect your cancer risk. Discuss them with your family and close friends. Then you can reach a decision that feels right for you.
If breast cancer spreads, it often goes to the lymph nodes first. Lymph node surgery is done to find out if cancer has spread to the lymph nodes.
The types of lymph node surgery for breast cancer are:
You may have lymph node surgery at the same time as a mastectomy or breast-conserving surgery. People with very early breast cancer, such as ductal carcinoma in situ, may not need lymph node testing.
Some types of endocrine therapy for breast cancer include:
Breast cancer is treated by surgeons, medical oncologists, and radiation oncologists.
Different health professionals can perform a breast exam to check for lumps or changes. They include:
You may see a general surgeon, a breast surgeon, or a radiologist if more evaluation of a breast problem is needed.
Possible problems from mastectomy or breast-conserving surgery include breast pain or numbness, buildup of blood or clear fluid in the wound, and the general risks of surgery. These include infection, bleeding, and reactions to the anesthesia. If lymph nodes under the arm were removed, swelling of the arm (lymphedema) may occur.
BRCA1 and BRCA2 are genes that normally help control cell growth. But an inherited change, called a mutation, in one of these genes makes you much more likely to get breast, ovarian, and some other cancers. BRCA (say "BRAH-kuh") stands for "BReast CAncer."
BRCA gene changes aren't common. Your doctor may talk to you about testing based on your family medical history or your personal medical history. Your doctor may ask you questions, such as if you have family members who had breast or ovarian cancer, if you were diagnosed with breast cancer before age 50, or if you have an Ashkenazi Jewish heritage.
If you are concerned that you may have a BRCA gene change, talk with your doctor.
In the table below, the figures are only rough estimates from research studies of females. These numbers may not apply to you, but they can give you an idea of how high your risk may be.
| Breast cancer risk | Ovarian cancer risk |
---|---|---|
Females without a BRCA gene change Females without a BRCA gene change | About 13 out of 100 will get breast cancer sometime during their lives. | About 1 out of 100 will get ovarian cancer sometime during their lives. |
Those with BRCA1 gene Those with BRCA1 gene | About 72 out of 100 will get breast cancer by age 80. | About 44 out of 100 will get ovarian cancer by age 80. |
Those with BRCA2 gene Those with BRCA2 gene | About 69 out of 100 will get breast cancer by age 80. | About 17 out of 100 will get ovarian cancer by age 80. |
Pictures may help you get a better idea of how much a BRCA gene change increases your risk for breast cancer and ovarian cancer.
Genetic testing can show if you have gene changes that increase your risk for breast cancer and ovarian cancer. Before you have genetic testing, you may want to see a genetic counselor. Counseling will help you decide about genetic testing. Both testing and counseling are often covered by insurance. But check with your insurance company to find out for sure.
Breast cancer is the growth of abnormal cells in one or both breasts. Cancer cells can spread to nearby tissues and form a mass, called a tumor. The cells can spread to the lymph nodes and other parts of the body.
Doctors don't know exactly what causes breast cancer. But some things are known to increase the chance that you will get it, such as your age and health history.
