The most common bone sarcoma of childhood is osteosarcoma. It is a type of cancer that primarily affects the bones, and it is the most common type of malignant primary bone tumor in children and adolescents. Osteosarcoma typically develops in the bones of the arms and legs, most commonly around the knee, and it can spread to other areas of the body such as the lungs. The cause of osteosarcoma is not known, but certain genetic conditions, exposure to certain chemicals, and radiation have been linked to the disease.
The most common symptoms of osteosarcoma include pain in the affected bone, swelling, and difficulty moving the affected area. Imaging tests such as x-ray, CT scan, and MRI may be used to diagnose osteosarcoma. Treatment typically involves surgery to remove the tumor, followed by chemotherapy and radiation.
Early diagnosis and treatment are important for the best outcome, so it is important for people to be aware of the signs and symptoms of osteosarcoma. If you or your child experiences any of the symptoms, it is important to contact your doctor for further evaluation.
