Osteosarcoma is the most common type of primary bone cancer. It’s most common in teenagers, young adults and adults in their 60s, but people of any age can be affected. It can occur in any bone, but is most likely to develop around the knee, in the thigh bone (femur), in the shin bone (tibia) or in the upper arm (humerus).
Ewing’s sarcoma is named after the surgeon who first described it. It is more common in teenagers and young adults, but it can occur at any age. It’s more likely to occur in young children than osteosarcoma is.
Any bone can be affected, but the most common sites are the pelvis, thigh bone (femur) and shin bone (tibia). It’s also possible for Ewing’s sarcoma to start in the soft tissues of the body. This is called extraosseous Ewing’s sarcoma (extra means outside, osseous means bone), or soft tissue Ewing’s sarcoma.
Chondrosarcoma is usually a slow-growing tumour and is most common in middle-aged people. The cancer starts in cartilage cells, although it can also grow inside a bone or on its surface. The most common places for it to develop are the upper arm (humerus) or thigh bone (femur), but it can develop in other bones, such as the ribs, pelvis or shoulder blade (scapula).
Spindle cell sarcoma
Spindle cell sarcoma is a rare type of bone cancer. It is similar to osteosarcoma, but normally occurs in adults over the age of 40. It’s extremely rare in people under 20. When spindle cell sarcoma is in a bone, it’s treated in a similar way to osteosarcoma. You may hear words like leiomyosarcoma or malignant fibrous histiocytoma (MFH) used to describe spindle cell sarcoma.
Chordoma is a rare cancer, which is normally slow-growing. It starts in the bones of the spine. It may be in the bottom of the spine (the sacrum), in the neck or in the bones at the bottom of the skull. It can occur at any age, but is more common in people over 40.
Angiosarcoma can occur at any age. It usually affects the soft tissues, but rarely it can develop in bone. Angiosarcomas can affect any bone. They can develop in more than one bone at the same time, or in more than one place in a single bone.
