Yes. Obesity is linked to a higher risk of breast cancer. Fat cells can actually make estrogen, even in men, and increased estrogen levels are associated with breast cancer. So although breast cancer is quite rare in men, obese men are more likely to develop breast cancer, just like obese women. And exercise is associated with a decreased risk of breast cancer... So get moving!
Yes. Any man can have breast cancer but, like other colleagues said, is more frequent in obese men. The rate is 1 men with breast cancer for every 100 women with it.
