What is Breast Cancer?

Breast cancer occurs when malignant (cancer) cells form in the tissues of the breast. Breast cancer types range from early, non-invasive cancer to more aggressive cancer that can spread to other parts of the body.

Breast cancer is sometimes caused by inherited gene mutations (changes).  The genes in cells carry the hereditary information that is received from a person’s parents. Hereditary breast cancer makes up approximately 5 to 10 percent of all breast cancer. Some altered genes related to breast cancer are more common in certain ethnic groups.

• The earliest detection of breast cancer is with a mammogram before there are external physical signs. Some breast cancers are detected by a lump, skin changes or nipple discharge.
• Women in the United States get breast cancer more than any other type of cancer except skin cancer. Breast cancer is second only to lung cancer as a cause of cancer death in women. Although breast cancer is most common in women, it can also affect men but the number of cases is small.
• There are many treatments available to cure breast cancer. The best chance for curing breast cancer is when it is detected and treated early before it spreads to other parts of the body.
