I am 17, recently I saw an article of how men could get breast cancer and I didn't know this before.. so I decided to feel around and under my left nipple i found a small lump like thing.. not even a cm big.. probably like half a cm. I've been worrying about this for days, is this something I should worry about or is this normal considering I'm alil chunky but not alot. I have not noticed any changes in my breast or anything or any soreness when i touch it. Please help
