Breast cancer is cancer that forms in the cells of the
breasts. After skin cancer, breast cancer is the most
common cancer diagnosed in women in the United
States.
Breast cancer can occur in both men and women, but it's
far more common in women. Substantial support for
breast cancer awareness and research funding has
helped created advances in the diagnosis and treatment
of breast cancer.
Breast cancer survival rates have increased, and the
number of deaths associated with this disease is steadily
declining, largely due to factors such as earlier detection,
a new personalized approach to treatment and a better
understanding of the disease.
