About Sarcoma
What are the symptoms of bone sarcomas?
In their early stages, there may be no symptoms. As the tumor grows, it may cause other symptoms, such as pain or soreness, as it presses against nearby nerves and muscles. Because the tumor is in the bone and can weaken the bone, osteosarcoma can sometimes present itself as a fracture.
This fact sheet deals with primary bone cancer.
