Types Of Bone Cancer

Osteosarcoma

The most common type of primary bone cancer is osteosarcoma. It is most commonly found in teenagers and young adults. But you can get it at any age. Osteosarcomas can grow anywhere in the skeleton. But the most common sites are the

 Ewing’s sarcoma

This type of bone cancer is named after the surgeon who first described it. It is most common in teenagers.
Ewing's sarcoma usually starts in the pelvis (hips), thigh (femur) or shin (tibia) bones. But you can also get a Ewing's tumour in the soft tissues of the body. Soft connective tissue tumours are called soft tissue sarcomas.
If you have a soft tissue Ewing's tumour, you will have the type of treatment described in this section. This is because these tumours respond to the same treatment as Ewing's bone tumours.

Chondrosarcoma

This type of primary bone cancer is most often found in adults over 40 years old. It is relatively rare – about as common as Ewing's sarcoma.
Chrondrosarcoma is a cancer of cartilage cells. Cartilage is the shiny, smooth substance that normally covers the ends of bones in the joints. It provides support for the joint and allows bones to move smoothly over one another.
Chondrosarcoma can grow inside a bone or on the bone surface. The cancer makes cartilage. So you may have islands of cartilage inside the bone or on the bone surface, in an area where it wouldn't normally grow.
This bone tumour is usually slow growing. The most common sites for chondrosarcoma are the

• Hips (pelvis)
• Thigh bone (femur)
• Upper arm (humerus)
• Shoulder blade (scapula)
• Ribs 

Spindle cell sarcoma

Spindle cell sarcomas are very similar to osteosarcomas but don't produce the bony substance called osteoid, which osteosarcomas do. They behave in a similar way to osteosarcoma and doctors treat them in a similar way. They are usually found in adults over 40. There are several types of spindle cell sarcoma including
Undifferentiated sarcoma of bone means that the cells are not specialised. They are quite undeveloped (immature) and it isn't possible to tell which type of normal bone cells they started from. If you have a spindle cell sarcoma with more well developed (specialised) cells, your doctor will call it a histiocytoma, fibrosarcoma or leiomyosarcoma, depending on the appearance of the cells under a microscope.
Malignant fibrous histiocytoma is a very rare type of spindle cell sarcoma. It tends to be found in middle aged adults. The arms and legs are the most common sites.
Fibrosarcoma is also very rare and most often found in middle aged adults. The most common site for fibrosarcoma is the thigh bone (femur).
Leiomyosarcoma of bone is extremely rare and very little is known about it.

Chordoma

Chordomas are a very rare, slow growing type of bone cancer. They are most common in people between 40 and 60 years of age. They are found more often in women than men. There are around 20 cases in the UK each year.
Chordomas develop from the notochord (pronounced no-tow-cord). The notochord forms the early spinal tissue in a baby developing in the womb. After about 6 months, this tissue is replaced by bone. But sometimes small areas of notochord may remain.
About 2 out of 5 chordomas (35 to 40%) grow in the skull or the bones in the middle of the face. The rest develop in the bones of the spine (the vertebrae). About half of these are in the lower part of the spine.
Chordomas do not usually spread. But if they do, the most common places are the lungs, nearby lymph nodes, the liver, and the skin.
