Breast cancer in men is rare, but it does happen (less than 1 percent of all breast cancer cases in the U.S.) .
Men have much less breast tissue compared to women and are not routinely screened for breast cancer.
Breast cancer screening is only recommended for some men at higher than average risk due to an inherited gene mutation or a strong family history of breast cancer.
For these men, screening may increase the chances breast cancer is found early, when the chances for survival are highest.
If you have concerns about your risk of breast cancer, talk with a health care provider.
Some men may have a higher than average risk of breast cancer, including those with a :

Learn about family history of breast cancer and breast cancer risk.
Learn about genetic testing for BRCA2 or BRCA1 mutations.
Breast cancer screening recommendations for men at higher than average risk are different from recommendations for women.
The National Comprehensive Cancer Network (NCCN) recommends men at higher risk for breast cancer, starting at 35 :
Men at higher risk for breast cancer should also be aware of the warning signs of breast cancer.
Men who have a BRCA1/2 gene mutation may also benefit from prostate cancer screening .
The most common sign of breast cancer in men is a painless lump .
However, any change in the breast (or chest area) or nipple can be a warning sign of breast cancer in men, including [59-60]:
Men tend to have much less breast tissue compared to women. So, some of these signs can be easier to notice in men than in women.
These symptoms may also be signs of a benign breast condition.
If you notice any of these signs or other changes in your breast or nipple, see a health care provider right away.

BRCA2 (BReast CAncer gene 2) is one of the most well-known genes linked to breast cancer in both men and women.
Men with a BRCA2 gene mutation have an increased risk of breast and other types of cancer, including prostate cancer [8,61-62].
A man can inherit a BRCA2 mutation through either parent. And, a man who has a BRCA2 mutation can pass the mutation on to his daughters and sons.
Most men with a BRCA2 mutation will never have breast cancer. However, the lifetime risk of breast cancer (up to age 80) is [61-64]:
Breast cancer in men is more likely than breast cancer in women to be related to an inherited gene mutation :
For this reason, it’s usually recommended that men diagnosed with breast cancer have genetic testing for BRCA2 mutations.
Other genes (including BRCA1) are under study for possible links to breast cancer in men .
