Bone Cancer: Bone cancer is a malignant bone tumor. There are several types of bone cancer, including osteosarcoma, Ewing's sarcoma, chondrosarcoma, malignant fibrous histiocytoma, fibrosarcoma, and chordoma. Symptoms and signs include pain, fracture, a lump or mass over the bone, fever, chills, anemia, and weight loss. Advancements in early diagnosis and treatment options have improved bone cancer prognosis. Though treatment for bone cancer depends upon the tumor location, cancer stage, and type of cancer, treatment usually includes surgery, chemotherapy, and/or radiation therapy.
