Breast cancer happens when normal cells in the breast change and grow out of control. Women sometimes discover they have breast cancer because they find a lump in one of their breasts. Breast cancer is much more common in women than in men. But men can get the disease. Breast cancer sometimes runs in families.

If you feel a lump in the breast, see the doctor or nurse right away. Breast lumps can be caused by conditions that are not cancer. But it is a good idea to have any lumps checked out.

Test for breast cancer — Doctors use a special kind of x-ray called a mammogram to check for breast cancer. If a mammogram finds a spot that looks like it could be cancer, doctors usually follow up with another test called a biopsy. During a biopsy, a doctor takes one or more small samples of tissue from the breast. That way the doctor can look at the cells under a microscope to see if they have cancer.

Breast cancer staging — Cancer staging is a way in which doctors find out how far a cancer has spread. The right treatment will depend, in part, on the stage of the cancer.

Treatment for breast cancer  

Surgery – Breast cancer is usually treated with surgery to remove the cancer. Many women with breast cancer can choose between mastectomy and breast conserving therapy (also called “lumpectomy”)

• Mastectomy is surgery to remove the whole breast. (If you choose this option, you might have to decide whether to have surgery to reconstruct your breast and when.)
• Breast conserving therapy (lumpectomy) is surgery to remove the cancer and a section of healthy tissue around it. Women who choose this option keep their breast. But they usually must have radiation therapy after surgery.
• Radiation therapy – Radiation kills cancer cells.
• Chemotherapy – Chemotherapy is the term doctors use to describe a group of medicines that kill cancer cells. Some women take these medicines before surgery to shrink the cancer and make it easier to remove. Some women take these medicines after surgery to keep cancer from growing, spreading, or coming back.
• Hormone therapy – Some forms of breast cancer grow in response to hormones. Your doctor might give you treatments to block hormones or to prevent your body from making certain kinds of hormones.
• Targeted therapy – Some medicines work only on cancers that have certain characteristics. Your doctor might test you to see if you have a kind of cancer that would respond to this kind of therapy.

After treatment— treatment will need to be checked every so often to see if the cancer comes back. Test usually including more mammograms. People should also watch for symptoms that could mean the cancer has come back. Examples of these symptoms include new lumps in the breast area, pain (in the bones, chest, or stomach), trouble breathing, and headaches. If  having any new symptom, mention it to the doctor.

Cancer comes back or spreads — that depends on where the cancer is. Most people get hormone therapy or chemotherapy. Some people also have surgery to remove new tumors.

Can breast cancer be prevented? — Women who are at high risk of getting breast cancer can sometimes take a medicine to help prevent the disease. If People have a strong family history of breast cancer, ask the doctor what can do to prevent cancer.

What will my life be like? — Many people with breast cancer do very well after treatment. The important thing is to take the medicines as directed and to follow all the doctors’ instructions about visits and tests. It’s also important to talk to the doctor about any side effects or problems have during treatment.
