If you have a BRCA2 mutation it is important to talk to your genetics specialist about your cancer risk.

When a man carries a cancer susceptibility gene mutation he has a higher risk of developing breast prostate and other cancers as well as the same 50 percent chance of passing that mutation on to his children as women.

BRCA1 BReast-CAncer-1 und BRCA2 BReast-CAncer-2. Despite the low number of patients in this study it could be concluded that mutations in BRCA1 and BRCA2 occur in male breast cancer patients of luminal A subtype. This page explains more about these risks.

But less often discussed is how BRCA gene mutations and other less-commonly known gene mutations can affect men. The BRCA2 gene provides instructions for making a protein that acts as a tumor suppressor. The spectrum of cancers is wide for BRCA2 and some studies report that the overall cancer risk for male BRCA2 carriers exceeds the risk for female carriers.

Diese Gene enthalten den Bauplan für Enzyme die Fehler und Schäden im Erbmaterial DNA.

Those with BRCA2 mutations unlike BRCA1 often develop aggressive prostate cancer and the 5-year survival rate is around 50 compared to a 99 5-year survival rate in the general population. Men who have a BRCA2 gene mutation have a higher risk of developing prostate breast and pancreatic cancer during their lifetime. However some individuals inherit a mutation in one of their BRCA genes which increases their risk for certain cancers including breast female and male ovarian pancreatic and prostate cancers as well as melanoma.

The function of the BRCA genes is to repair cell damage and keep breast ovarian and other cells growing normally. Men with these mutations have an increased risk of breast cancer especially if the BRCA2 gene is affected and possibly of prostate cancer. Everyone has BRCA1 and BRCA2 genes.

The BRCA2 protein is involved in repairing damaged DNA.
