Radiotherapy for myeloma can play a certain effect, but radiotherapy is not the main treatment means for myeloma, and it is only applicable to some patients. Myeloma generally refers to multiple myeloma, which is a kind of plasma cell malignant tumor, and the main treatment means is systemic chemotherapy. For some patients with multiple myeloma who have pathological fracture or high risk of spinal cord compression syndrome caused by compression of the spinal cord, local radiotherapy can be adopted to reduce the occurrence of complications. Generally speaking, local radiotherapy can not only reduce the risk of pathological fracture and other complications of myeloma, but also alleviate the pain and other clinical symptoms to a certain extent, so it has certain therapeutic effect for myeloma patients.
