Check for a lump: I would advise that you use your hand and look for any lump in your breast. Unless you feel a lump, there is no reason to worry. A physical examination by your PCP is the best way to be sure that there is no lump in your breast. To further assure you, Breast caner related lumps are painless. Since you have pain, it is likely to be related to hormonal changes that take place with monthly cycles.
