About breast cancer

Despite it being rare, breast cancer can also occur in men. Men over the age of 60 are more likely to get the condition whose symptoms include a lump in the breast – usually hard, painless and non-mobile, an inverted nipple, nipple discharge, which may contain blood, a persistent sore or rash around the nipple, hard, red or swollen skin surrounding the nipple and small bumps in the armpit, which are swollen glands.

Also, the mortality rate is higher for men with breast cancer than for women who are diagnosed with it.
