Osteosarcoma

Alternative Names:

Osteogenic sarcoma

Symptoms:

Bone pain.
Tenderness, swelling, or redness at the site of the bone pain.
The first sign may be a bone fracture. The tumor may cause weakness in the affected area of the bone. A fracture at the site of the tumor is called a "pathological fracture" which occurs after what often seems like a routine movement. For example, a young athlete who breaks an arm during a routine throw should be tested to ensure there is no underlying bone problem, such as a tumor or cyst.

Signs and tests:

X-ray
