What are the symptoms of osteosarcoma?

Osteosarcoma is a malignant tumor occurring in the skeletal system. The typical clinical symptoms of osteosarcoma mainly include pain, mass and pathological fracture, and can also be accompanied by systemic symptoms of malignant tumors. The pain is often mild at the beginning. As the disease progresses, the pain gradually increases, presenting persistent nocturnal pain. The swelling mass can be locally formed at the location where the tumor occurs, and the local skin temperature is elevated. At the same time, if the mass grows rapidly, varicose veins can be seen on the surface. Pathological fracture is often caused by the destruction of bone by tumor, and fracture occurs at the corresponding part, which affects the body activity. At the same time, osteosarcoma, as a malignant tumor, will also appear weight loss, anemia, fever and other systemic manifestations.
