Hi Anya - I don't know your age, but I'll assume you're young. You sound very well informed - with your family history of breast cvancer, this is a good thing. Congratulations! Although what you describe doesn't sound like cancer (considering it's been going on for several months), I'd go visit the doctor simply to set your mind at ease, and to perhaps get something to address your pain/soreness. go ahead and make that call - no sense being in pain if you don't have to be, eh? Good luck - PJH
