As a kid, i had this mole between my areola and my breasts' skin. Now i'm going through puberty and my boobs grew, the mole stretched out and has a reddish colour to it. Is this cancer, or just grew out?
Answer:
Normally I would tell you to get that checked immediately, but since it only grew as you grew, it's not an immediate threat. Now you need to determine whether it has changed in shape, color, or if it causes you pain. An irregular edge and a change in shape (such as going from being round to oval) or a change in color can signal cancer, and if it causes you any pain at all, get it checked. If it still concerns you, see a dermatologist and they’ll be able to give you information on it.
I have some skin issues similar to yours (I have red raised hard bumps on my skin about the size of half a quarter, and they just kept popping up). I went to the physician anticipating the worst (I have a history of cancer in my family) and it turns out it's just a skin disorder I got from my dad where my skin forms raised scar tissue for no reason on my chest, shoulders and upper back. The skin problems were perfectly healthy, no cancer, no worries. But they do cause me pain and itching, so I’m getting them removed.
Just listen to yourself, if you've got worries, get them checked out. But most likely it just grew out as you grew, so if it doesn't change, then don't be too worried!
