I have been having on and off again pain in one of my breasts, its like a shooting pain. i do usually have pain during my period, but this happens even after my period. and is different from the pain i experience during my period. i also have a very visible vein on my areola, i have had it for years. i am slightly overwieght, smoke, have Polycystic ovary syndrome, on contraceptive, on anti depressants and have no history of cancer in the family. should i be worried?
