Bone tumor

A bone tumor is an abnormal growth of tissue in bone that can be benign or malignant, with primary bone cancers like osteosarcoma and Ewing sarcoma being rare and mainly affecting children and young adults, while more common cases involve cancer spreading to the bones from other parts of the body. Typical symptoms include persistent bone pain, potential lumps, neurological signs from pressure, and possibly a pathologic fracture, with other symptoms such as fatigue, fever, weight loss, anemia, and nausea.
