Friend started experiencing little pain& swelling in right breast.Can it Cancer?

That's the best thing you could've told her to do. It could be a number of things, and the only way your friend will know for sure is to get it checked by a professional. Only recently, my wife had painful swelling in one of her brests, and it turned out to be nothing to worry about. I think it was put down to ill fitting bras.

Well, you did right in telling her to get medical attention - one can never be too careful. Even if it's NOT cancer it needs dealing with. One possibility is a blocked milk duct - these can cause pain and swellings. But she's wise to go to see a doctor. Best of luck for her.

seeing the doctor is definatly the smart thing to do. hopefully it is NOT cancer. but if it is, discovering it now gives her a much better chance of surviving and possibly ridding herself of it completly without having to undergo a masectomy. better safe than sorry.

Its good you adviced her to go see the doctor; don't lets assume. the earlier cancer is diagnosed and treated the better. Please, let her act fast cos a stitch in time saves nine! thanks.
