Besides skin cancer, breast cancer is the most commonly diagnosed cancer among American women. In fact, about 1 in 8 U.S. women will develop invasive breast cancer over the course of her lifetime.
A man’s lifetime risk of breast cancer is only about 1 in 1,000.
In 2016, an estimated that over 245,000 new cases of invasive breast cancer are expected to be diagnosed, along with 61,000 new cases of non-invasive breast cancer in women in the U.S. About 40,450 women in the U.S. are expected to die in 2016 from breast cancer. Although these statistics seem high, actual death rates have been decreasing. These decreases are thought to be the result of treatment advances, earlier detection through screening, and increased awareness.
Breast cancer typically starts from different parts of the breast. Most common breast cancers begin in the ducts that carry milk to the nipple, or the cells of the glands that make breast milk (i.e., lobules). It’s important to understand that not all breast lumps are cancer. However, any breast lump or change in your breast needs to be checked by a health care provider.
