Hi, 44 yr old female w/ bc history. 2000 IDC, 3cm, no nodes. Lump/Rad/chemo. Reoccurence 2008 same breast, IDC 1cm, no nodes, mast. more chemo. Now DCIS, no invasion, in right breast, Mast scheduled. Rib pain in lower quad of right rib cage- from bra line to right tip of rib cage. xray Jan 2011 clear. Bone scan Feb 2011 clear. Catscan (for lung) March 2011 all normal. After 3 cancer diagnoses- admit to high anxiety. With all these tests, possible it's costrochondritis, fibromylgia or just something else other than rib mets?
