In the bathroom mirror when I get in the shower, I've noticed there's a red path of skin on my left boob(I've noticed it for a while now, I hate having boobs, so I never have anything to do with that area, so unless it's unavoidably in front of me I don't look at them. Certainly don't check them. I'm 43 and in perimenopause. My mother died of cancer, in that area, diagnosed at 46. It's only recently occurred to me that that could be a symptom. I'm waiting to move house at the moment, and my Dr's are awful so I'm not going to them. Is there anything else it could be?
