Breast cancer affects more than 279,000 people in the United States each year (according to Cancer Statistics, 2020).
It is the 1rst most common cancer in women with 276,800 new cases and the 2nd case of death by cancer in women with 42,170 death.
This cancer is frequentless for men with 2,680 new cases and 520 death. Of note, the incidence of breast cancer has been increasing for the past 20 years, but with decreasing mortality.
This cancer most often develops after the age of 60, and the risk increases with age. That said, it can affect younger women, with 20% of breast cancer cases occurring before the age of 50.
About 5% of all breast cancers occur based on a family genetic background (e.g., BRCA or PALB2 mutations.)
