Tumor of the bony skeleton and/or soft tissue

Bone tumors, or bone cancer, is a primary cancer that starts in the bone or cartilage. These tumors may be benign, malignant, or indeterminant. The radiologist will give a likelihood of the type of tumor it is based on its imaging characteristics. It is more common in children, adolescents and young adults. The most common types of malignant bone tumors in young adults is chondrosarcoma and osteosarcoma. Other non-cancerous types are osteoma, osteoclastoma (giant cell tumors) and osteochondroma. Rarer types of bone cancer are: fibrosarcoma, angiosarcoma, and undifferentiated high-grade pleomorphic sarcoma. The tumor can grown into the bone as well as neighbouring tissue. Most are called sarcomas.A chondrosarcoma is the most common in adults. It originates in the cartilage. It is typically found in the long bones - humerus and femur. It is a slow growing cancer.Osteosarcoma is second most common bone cancer in adults. It is most often found in the knees, tibia,and long bones. It can also be found in the hips and jaw in older adults.Soft tissue tumors can also occur. These include: lipomas, fibromas, desmoid tumors, leiomyoma, leiomyosarcoma, schwannoma, liposarcoma, synovial sarcoma, and neurosarcoma.
