5 Deadliest Cancers in the U.S.

4. Breast Cancer

Estimated Deaths: 43,700

Breast cancer is cancer that is found in the tissue of the breast. While it can affect both sexes, it is far more common in women than men. Mainly occurring in middle-aged and older women, it makes up about 30% (or 1 in 3) of all new female cancers each year. Despite being the second leading cause of cancer death in women, breast cancer death rates have consistently and significantly decreased since 1989, with a remarkable overall decline of 43% as of 2020. This positive trend is attributed to multiple factors, including the early detection of breast cancer through screening methods, heightened awareness about the disease, and advancements in treatment options.
