Breast Cancer in Women


What is breast cancer?

Breast cancer develops when cells in the breast grow out of control. Several types of breast cancer can develop, depending on which cells turn into cancer. Most breast cancers start in the tissue or ducts of the breast.

What increases my risk for breast cancer?

  • Older age
  • A family history of breast, ovarian, prostate, or pancreatic cancer, or breast cancer 1 (BRCA1) and breast cancer 2 (BRCA2) genes
  • First monthly period before age 12, or menopause that starts after age 55
  • Long-term use of estrogen or progestin, or exposure to chest or face radiation before the age of 30
  • First pregnancy after the age of 30, not breastfeeding, or never giving birth
  • Being overweight or obese, eating large amounts of high-fat food, or lack of physical activity
  • Use of cigarettes or alcohol

What are the signs and symptoms of breast cancer?

  • Swelling or a lump in your breast, or swollen lymph nodes under your arm
  • Bleeding or clear discharge from your nipple
  • Breast that aches, or feels sore or heavy
  • Dimpled breast skin (like an orange peel), or a sudden red area on the skin
  • Nipple that looks like it has been pushed in

How is breast cancer diagnosed?

You may need several tests to diagnose changes in your breasts. You may have already had a mammogram. Your healthcare provider may have needed a closer look at your breasts. He or she may have ordered an MRI or ultrasound of your breasts. During the ultrasound, the provider may have taken samples of the fluid or tissue he or she saw. A biopsy is used to remove fluid and tissue. They are sent to lab to be tested for cancer.

How is breast cancer treated?

Treatment depends on the size of the tumor, if it has spread, and if it responds to hormones. Treatment also depends on your age and the type of cancer you have. Some types grow more slowly than others. Your healthcare provider will talk to you about the benefits and risks of treatments that might be right for you. He or she will help you decide on treatment that best fits your needs and goals.

  • Hormone medicine may be used if the cancer is sensitive to hormones.
  • Radiation therapy uses high-energy x-ray beams to kill cancer cells.
  • Chemotherapy medicines are used to kill cancer cells. You may receive one medicine or a combination of medicines.
  • Targeted therapy is medicine that finds markers on some cancer cells and kills the cells.
  • Surgery may be used to remove the tumor. Surgery called mastectomy may be used to remove all or part of your breast. A mastectomy may be done to treat breast cancer or prevent cancer from spreading.

What can I do to manage breast cancer?

  • Ask questions. You will receive a lot of information about breast cancer and treatment. Questions will help you understand the information better. You may not have questions until after your appointments. Write your questions down. Call or e-mail your doctor any questions you have.
  • Eat a variety of healthy foods. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Ask if you need to be on a special diet.
    Healthy Foods
  • Drink liquids as directed. Ask how much liquid to drink each day and which liquids are best for you. Drink extra liquids to prevent dehydration. You will also need to replace fluid if you are vomiting or have diarrhea from cancer treatments.
  • Exercise as directed. Ask your oncologist about the best exercise plan for you. Exercise may help decrease the side effects of treatment, such as nausea, vomiting, and weakness. It may also help improve your mood. Stop exercising if you feel pain in your chest, have trouble breathing, or feel dizzy. Do not exercise if you have a fever or if you had anticancer medicines through an IV in the last 24 hours.
    Walking for Exercise
  • Do not smoke. Nicotine can damage blood vessels and make it more difficult to manage breast cancer. Smoking also increases your risk for new or returning cancer and delays healing after treatment. Do not use e-cigarettes or smokeless tobacco in place of cigarettes or to help you quit. They still contain nicotine. Ask your healthcare provider for information if you currently smoke and need help quitting.
  • Limit or do not drink alcohol as directed. Your oncologist may tell you to limit or not drink alcohol. Alcohol increases the risk for new or returning breast cancer. If you choose to drink, limit alcohol to 1 drink per day. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
  • Talk to your healthcare provider about family planning. Some types of treatment, such as chemotherapy, may affect your ability to have a baby. Your provider will talk with you about options if you want to have children.

Call your local emergency department (911 in the US) if:

  • You have chest pain when you take a deep breath or cough.
  • You suddenly feel lightheaded or short of breath.
  • You cough up blood.

When should I seek immediate care?

  • Your arm or leg feels warm, tender, and painful. It may look swollen and red.

When should I call my doctor or oncologist?

  • You have a fever.
  • You have any new or different pain.
  • You are vomiting and cannot keep food or liquids down.
  • You are depressed or feel that you cannot cope with your illness.
  • You have questions or concerns about your condition or care.
