breast pain

I have been having pain in my right breast - somethings it's a sharp shooting pain and other times it's a dull constant pain.  I don't have it everyday, just once in a while.  It has been going on for about a year.  I do self breast examinations every month and found no lumps.  I'm 41 years old and have 2 kids (a 4 1/2 yr old and a 2 1/2 yr old).  I breastfed my youngest for a year.  I went for a mammogram and it came back normal (thank god).  The doctor there told me it was normal to have pain - that some women have pain and it means nothing is wrong.  Is that true????

Dear nani2boots1:  Intermittent breast pain is very common and often varies with one’s menstrual cycle.  Most breast cancer is not painful.  If you are concerned, you may want to see a medical breast specialist (often affiliated with large academic medical centers) who can evaluation and make recommendations for further evaluation and treatment, if appropriate.

yes, that's true of some friends of mine.  but if you're worried, get a second opinion, it can't hurt.
