I have a hard, "jelly bean sized", firm, non
-movable lump on
left side of my sternum, right between my breast
s. I've had no injury to the area, it is not discolored & have had this bump for a couple of years. During a mammogram a couple years ago, a "marker" was placed over this area, however the marker moves with my skin, and since the lump
is fixed on
my sternum, it doesn't show in a mammography.
