Osteosarcoma is the term for a type of bone cancer. It occurs when bone-growing progenitor cells divide out of control and form a tumor. Anyone can get bone cancer, but it is the most common cancer in children and adolescents, especially teenage boys. Treatment of bone cancer is multimodal therapy, combining chemotherapy, radiation and surgery.

Proper nutrition is especially important in cancer prevention and treatment. Cancer treatments and the cancer itself can change the body's appetite and tolerance for certain foods. Therefore, building a reasonable, balanced diet is the top concern of cancer patients.
