Signs of possible breast cancer in men include:- • Lumps in the shower that are either under the nipples and the areola. This is usually hard, painless, and does not move around within the breast. • The nipple may turn inwards • There may be fluid oozing from the nipple (nipple discharge), which could be streaked with blood. • There may be a sore or rash around the nipple that does not go away. • About 40% of breast cancer in men is estrogen-positive and many have this hormone in their urine.
