What is the most common type of osteosarcoma?
The most common subtype of osteosarcoma is conventional central osteosarcoma. The other subtypes are much less common. They each account for less than 5% of all osteosarcomas. Grade is the most important factor in treatment decision-making.
Is osteosarcoma highly malignant?
Osteosarcoma is a primary malignant tumour of the skeleton characterised by the direct formation of immature bone or osteoid tissue by the tumour cells. The classic osteosarcoma is a rare (0.2% of all malignant tumours) highly malignant tumour, with an estimated incidence of 3 cases/million population/year.
Is chondrosarcoma a terminal?
A chondroma, also called exostosis or osteochondroma, is a benign bone tumor. Benign bone tumors are not sarcomas. Benign bone tumors do not spread to other tissues and organs, and are not life threatening.
What does osteosarcoma look like?
The cancer cells in these tumors look like early forms of bone cells that normally help make new bone tissue, but the bone tissue in an osteosarcoma is not as strong as that of normal bones. Most osteosarcomas occur in children and young adults. Teens are the most commonly affected age group, but osteosarcoma can develop at any age.
Is osteosarcoma related to rapid bone growth?
Osteosarcoma in older adults is often linked to another cause, such as a long-standing bone disease. Children with osteosarcoma are usually tall for their age. This also suggests that osteosarcoma may be related to rapid bone growth. Osteosarcoma is more common in males than in females.
What are the treatment options for osteosarcoma?
