Breast Cancer Awareness Month AACR

Breast Cancer Awareness Month

October is Breast Cancer Awareness Month, an annual campaign to raise awareness of this complex disease and fund research into its causes, treatment, and cure. Since 1985, individuals, businesses, and communities have come together every October to show their support for the many people affected by breast cancer.

According to the National Cancer Institute, almost 298,000 women in the United States will be diagnosed with breast cancer and more than 43,000 will die of the disease in 2023. In addition, an estimated 2,800 men are expected to be diagnosed with breast cancer and 530 will die this year.

Men can also develop breast cancer, making up slightly less than 1 percent of those diagnosed yearly. Radiation exposure, high levels of estrogen, and a family history of breast cancer can increase a man’s risk of the disease.


Please see The American Association for Cancer Research page on breast cancer for more information on prevention, screening, and treatment, as well as breast cancer treatment during pregnancy.

Breast Cancer Awareness Month, held in October every year, aims to promote screening and prevention of the disease, which affects one in eight women in the United States every year and 2.3 million women worldwide. Known best for its pink theme color, the month features a number of campaigns and programs — conducted by groups ranging from breast cancer advocacy organizations to local community organizations to major retailers — aimed at:

• supporting people diagnosed with breast cancer, including metastatic breast cancer
• educating people about breast cancer risk factors stressing the importance of regular screening, starting at age 40 or an age that’s appropriate for your personal breast cancer risk
• fundraising for breast cancer research

Metastatic Breast Cancer Awareness Day

October 13 is nationally recognized in the United States as Metastatic Breast Cancer Awareness Day. About 30% of early-stage breast cancers eventually metastasize (spread to parts of the body away from the breast), and the day is intended to drive awareness of the need for more research about metastatic disease. 

Men’s Breast Cancer Awareness Week

Although breast cancer is much more common in women, breast cancer affects men, too. In 2021, U.S. President Joe Biden designated October 17 to October 23 Men’s Breast Cancer Awareness Week. About 2,710 American men this year are expected to be diagnosed with breast cancer, and about 530 are expected to die from the disease. But lack of awareness and stigma can be barriers to detection and care. Some men, trans men, and non-binary people choose to call their cancer chest cancer.
