6 year osteosarcoma survivor, with new lump on breast! Help!

DanaMarnie

Hi guys, I am a 25 year old osteosarcoma survivor. I was diagnosed in 2007 and underwent surgery and chemotherapy. My primary site was in my right mandible, and it never spread. Last night while showering, I felt a large mass in my upper right breast, and I am freaking out! I contacted the hospital and should be able to get in to see someone in the next few days, but I am going crazy thinking the worst. Has this happened to anyone else out there? How did it go? Thanks for your help.
