Hello I m male 24 years old. i wanted to ask you, just few minutes ago while showering i noticed a small lump on my right breast just next to my nipple. I don t know is it like acne, cyst or something else. It showed up like in last 48 hours before i didn t noticed it. it doesn t hurt, just a bit hard. surface is maybe a bit red, but maybe because i was touching it. Should i be worried about this and get checked up by doctor or wait for a couple of days and see if it will disappear. Thanks.
