Any feeling, whether you have it yourself or whether you actually palpate it is important and you should have it looked at. After the first test, doctors are pretty much sure and they perform additional tests to make sure that they were not mistaken. No need to worry!

I found some little lumps in my breast, and went to have a mammogram.  I was so worried!  They even had to take extra pictures, but determined that I was okay.  How do you know if you need to have the lumps checked out?  Or should you have every lump looked at? 

I have an area that almost always sore on the side of one breast, but there is nothing there.  Is that something to worry about?
