Men who carry a specific genetic mutation known as BRCA2 are at significantly greater risk of developing breast cancer than men who don’t carry it. Other things that put men at a greater risk of developing breast cancer are previous radiotherapy to the chest, sex hormone dysfunction, being older and having a close relative with the disease.
So what can men do? Physical checks can be much more effective in men because they have a smaller amount of breast tissue. Men should get in the habit of self-examination. See breast self-exam: horizontal techniques for male chest exams.
