Osteosarcoma is a bone tumor that consists of malignant cells that produce immature bone. It is the most common type of bone cancer in children and adolescents and affects more males than females. Nearly 80% of osteosarcomas appear in the distal femur, the portion of the thigh bone closest to the knee, or the proximal tibia, the lower leg bone near the knee. Osteosarcoma may also develop in the proximal humerus, the upper arm bone connected to the shoulder.
Of all childhood cancers, osteosarcoma is rare, but it is the most common bone tumor in children; it affects approximately 400 children under age 20 every year.
Osteosarcomas are classified as low, intermediate or high-grade tumors. A low-grade osteosarcoma has few dividing cells in the tumor, while a high-grade osteosarcoma is filled with dead tumor cells. Most tumors that occur in children are high-grade.
