osteosarcoma

Two months ago my son was diagnosed with osteosarcoma on the lower end of the fibula bone just above the right ankle. He is undergoing chemotherapy now. It seems that this disease mostly occurs either on the tibia below the knee or on the bone above the knee but not near the ankle. He will have surgery to remove the tumour and part of the fibula bone and it seems a tricky operation. I would like to hear from anyone who had a tumour in the same place and had surgery

Thanks. My email is wan13@newtelsurf.com
