What is Osteosarcoma?

Osteosarcoma is a type of sarcoma. Osteosarcoma is the most common type of malignant bone tumor. It develops in the bones, cartilage, fibrous tissue, and bone marrow.

Because osteosarcoma is so rare, it's important to receive treatment at cancer centers, such as the Abramson Cancer Center that has experts in sarcoma and orthopaedic oncology.

While our sarcoma program treats adults, we have a relationship with the Children's Hospital of Philadelphia. For information about treatment of sarcoma in children, visit the Children's Hospital of Philadelphia.

Osteosarcoma Symptoms

Common symptoms of osteosarcoma include:

  • Pain
  • Swelling
  • A lump on the bone
  • Bone fractures

If the tumor spreads beyond the bone, other symptoms such as chest pain, shortness of breath, cough, fever, weight loss, and weakness may occur.
