Less than one percent of all breast cancers in the world occur in men. The reasons why men get breast cancer are still unknown, but certain lifestyles can increase the chances of getting the disease.
Breast cancer history in your family puts you at greater risk of getting the disease than those who didn’t have it in their family. Faulty genes called BRCA1 and BRCA2 are the ones that cause the disease when inherited from a family member.
Obesity is another possible cause of breast cancer in men as it can increase levels of estrogen in the body. Liver cirrhosis and Klinefelter syndrome are some other conditions that can increase levels of estrogen and thus cause cancer. You can read more about estrogen and breast cancer connection here.
Science still hasn’t found is there anything a person can do to reduce the risks of getting breast cancer, but it’s recommended to eat a well-balanced diet, and avoid recreational drugs and alcohol as it may help.
