Male breast cancer risk is increased by having a family history of the disease similar to the situation found in women. However, hormonal mechanism may have commonalities and differences between the risks factors.
Since male breast cancer is so uncommon there is uncertainty regarding the risk factor especially the environmental ones. Bone fracture markedly increases the risk for men but to women it decreases. Analysis revealed that breast cancer among men had significant increased risk when a first degree relative is also infected with it. Obesity is another risk for breast cancer in men. The influence of shared genetic and environmental risk factors reflects particularly due to the alterations in the bioavailable ratio of estrogen to testosterone.
