painful breast lump

I have a lump in my left breast that is extremely painful, especially to the touch. It is visible and red. There is no break in the skin, so I doubt that it is an insect bite. I know that cancerous lumps are for the most part are not painful. I have been taking advil for 2 days hoping that would aleviate the pain, but it has not helped. Should I be concerned with this lump?

Dear Gracie72:  Without examination, it is not possible for us to speculate on what this "lump" might be.  If this lump is on the skin, it should be noted that breast skin is like other skin and is subject to skin abnormalites, pimples, etc.  If this gets worse or does not get better, or if you are concerned, you should have your doctor do an examination.

I would have it checked by your doctor.
