July 2012 found IDC in right breast. After surgery, some lymph nodes were taken to check for cancer thats when they found castlemans. Ive already been staged(loads of tests done) with hyaline vascular multicentric. I am neg. for HIV/Aids and HHV8. Will go to Mayo Clinic after my radiation treatments are done. My question is does anyone have this disease and if so, what am i to expect???Is there any support groups?
