11 Factors That Put You at Risk for Male Breast Cancer
Men with liver disease may be at an increased risk for breast cancer. It's not necessarily common knowledge, but liver disease often causes increased estrogen levels in men, thereby increasing the risk for breast cancer.
Have an alcohol problem? Then you're at a higher-than-average risk for male breast cancer. Does this seem like a strange connection? It's thought that one of the main reasons why heavy drinking increases the risk of male breast cancer is because of liver disease caused by drinking, which, as discussed previously, can increase estrogen levels in the body.
Obese men tend to have higher estrogen levels than average, probably because fat cells can transform androgen hormones (male hormones) into estrogens. This increases the risk for breast cancer.
Klinefelter syndrome increases the risk for breast cancer. What is Klinefelter syndrome? Men born with this condition have one or more extra X chromosomes and have various other physical changes or problems as a result. One of the changes common with Klinefelter syndrome is small testicles, often accompanied by infertility. Men with Klinefelter also have higher estrogen levels than normal.
Studies suggest that having an undescended testicle increases the risk of breast cancer. Similarly, having one or both testicles removed surgically also appears to increase the risk. Having a case of mumps as an adult (which often affects the testicles) can increase the risk too.
Early research suggests an intriguing connection between male breast cancer and certain occupations that involve chronically warm working conditions or heavy exposure to gasoline fumes. However, these findings are preliminary, and more research is necessary before definitive conclusions can be made.
