I'm a breast cancer survivor (2005) who had chemo & rad. Shortly after I finished, I developed a soreness on the chest wall and oncologist said no concern, it was Costochondritis which can develop after rads. In March, I developed a soreness on the rib below my treated breast. It comes and goes and is relieved by acetaminophen, and other BC patients report this troubling side effect of rads. But, the troubling thing is I've now developed anemia. I've been checked out by a gastro, no internal bleeding. Could these two events be linked? I think I've already answered my own question and should call my oncologist, but has anybody else experienced anything similar? Thanks.
