I don't  have breast cancer, but found this group three years ago when I
had a lumpectomy.  I got lucky.

My question today is:  Does a breast lump become suspicious only when it
is located near or under the armpit?

I have a sore spot (not sure if it could be classified as a lump) of
tiny bumps located near the edge of my breast,
at center of my chest. It is still on the breast, but opposite the
armpit.  Should I be concerned even if the sore area is not near the
armpit?  I just had a mammogram in February and all was good.

Thanks.
