Radiation-induced sarcoma is a rare but serious complication that can occur in patients who have received radiation therapy. Sarcomas are malignant tumors that arise from connective tissues in the body, such as bone, muscle, or cartilage. When these tumors develop in a previously irradiated area, they are referred to as radiation-induced sarcomas. These tumors can develop months or even years after the initial radiation therapy, and the risk of developing a radiation-induced sarcoma increases with higher doses of radiation. Diagnosis of radiation-induced sarcoma can be challenging, as symptoms may be similar to other conditions or may not present until the tumor has grown significantly. Treatment for radiation-induced sarcoma typically involves surgery to remove the tumor, followed by additional therapies such as chemotherapy or radiation therapy. Prognosis for patients with radiation-induced sarcoma can vary depending on factors such as the size and location of the tumor, the stage of cancer, and the overall health of the patient.
