Breast cancer accounts for roughly 30 percent of all new cancer diagnoses in women each year, making it the most common cancer among women in the United States after skin cancers. The lifetime risk for a woman developing breast cancer is about 1 in 8.
Breast cancer incidence has been increasing in recent years, with a slightly higher rate in women under 50. On a more hopeful note, about two-thirds of cases are identified at an early stage, when the cancer hasn’t spread beyond the breast, and treatment is generally more effective.
