True False
True With less than 3000 reported cases each year,primary bone tumors compose less than 1% of all tumors.
Free
True False
True Osteosarcomas (35% of all primary bone tumors),chondrosarcomas (26%),fibrosarcomas (6%),and giant cell tumors of the bone (5%)are all resistant to radiation or have a low sensitivity to radiation.Only Ewing sarcoma (16%)and multiple myeloma are sufficiently radiosensitive to indicate radiotherapy as a portion of the standard of care.
