While gynecomastia is not a risk factor for breast cancer itself, it can be
associated with an increased risk of breast cancer in some cases. Men with gynecomastia caused by an underlying condition such as Klinefelter syndrome or liver disease may have an increased risk of developing breast cancer. Additionally, some medications used to treat gynecomastia, such as estrogen blockers, may increase the risk of breast cancer. Therefore, men with gynecomastia should discuss any additional screening or surveillance needed with their healthcare provider to ensure early detection and treatment if breast cancer does occur.
