Breast cancer is a malignant (cancer) tumor that starts from cells of the breast. It is found mostly in women, but men can get breast cancer, too. About one-percent of all breast cancer diagnosed is diagnosed in men.
Excluding cancer of the skin, breast cancer is the most common cancer among women. Breast cancer accounts for one-third of all cancers diagnosed in Missouri, and is the leading cause of cancer deaths in women after lung cancer. Nearly all breast cancers can be treated successfully if detected early. When detected in the earliest stages, the cure rate is 97 percent.
A number of risk factors have been identified, but most women do not have any known risk factors at the time of their diagnosis. The biggest risk of a breast cancer diagnosis is being a woman and getting older. Breast cancer diagnosis and breast cancer deaths increase age. Ninety-five percent of new cases and 97 percent of breast cancer deaths occur in women aged 40 and older.
At this time, there is no guaranteed way to prevent breast cancer for women who are at average risk, which is why screening by mammography, clinic breast examination, and breast self-examination is so important.
