Run For The Cure Foundation (RFTC) Japan is a non-profit organization dedicated to saving lives through breast cancer education, early detection, and compassionate support.
BRCA1 and BRCA2 are genes that help repair damaged DNA and protect against cancer. Harmful (pathogenic) mutations in these genes can be inherited by men and women. Although men generally have lower cancer risks than women, BRCA mutations can still have important health implications.
What does it mean for men to carry a BRCA mutation?
BRCA mutations can be inherited from either parent
Each child of a parent with a BRCA mutation has a 50% chance of inheriting it
Men may have no symptoms, but can still pass the mutation to their children
Cancer risks for men with BRCA mutations
Risks vary by gene and family history:
Male breast cancer
BRCA1: about 1–2% lifetime risk
BRCA2: about 6–8% lifetime risk (much higher than average)
Prostate cancer
BRCA1: moderately increased risk
BRCA2: significantly increased risk, often earlier and more aggressive
Pancreatic cancer
Increased risk with both BRCA1 and BRCA2
Melanoma
Higher risk, particularly with BRCA2
Who should consider genetic testing?
Men may be advised to consider genetic counseling and testing if they have:
Male breast cancer at any age
Prostate cancer diagnosed at a younger age or with aggressive features
A family history of breast, ovarian, pancreatic, or prostate cancer
A known BRCA mutation in the family
Ashkenazi Jewish ancestry with a relevant family history
Testing is usually done after genetic counseling to understand what the results may mean.
Screening and risk management for men
Men with a BRCA mutation may benefit from:
Clinical breast exams Increased breast awareness
Prostate cancer screening starting earlier than average
Consideration of pancreatic cancer screening in certain high-risk families
Regular skin checks for melanoma
Specific screening plans should be personalized with a healthcare provider.
Why this matters for families
Even if a man never develops cancer, knowing his BRCA status can be critical for:
Informing children and relatives who may also be at risk
Making informed health and family decisions
Takeaway
BRCA mutations are not just a women’s issue.
For men, understanding genetic risk can lead to earlier screening, better outcomes, and lifesaving information for family members.
If you are concerned about your personal or family history, talk with a healthcare provider or genetic counselor.
