In the 1st part of July I found a lump in my right breast. Dr said he thought it was normal breast tissue, but sent me for a mammogram and ultrasound- results both normal. Towards the end of July I started to have a slight burning sensation in my breast and then my nipple felt like it was leaking, although it wasn't. That went on for a couple days, then my nipple felt normal again, but the burning has never went away. The sensation is intermittent, lasting only a second, but happening almost daily for the last 2 months. My Dr doesn't know what is causing it, but is sending me for another mammogram in Dec. Do you have any ideas? I try to tell myself that with a clear mammogram and ultrasound I should feel pretty confident that it's not cancer, but since it isn't going away, it's hard not to worry. Thanks
