Types of Bone Cancer

Benign (noncancerous) bone tumors are more common than malignant (cancerous) ones. Although benign tumors do not spread, and are rarely life threatening, both types may grow and compress healthy bone tissue and absorb or replace it with abnormal tissue. There are different types of bone cancer :

Osteosarcoma

– It is the most common type of primary bone cancer.
– It is a malignant bone tumor.
– This cancer starts in the bone cells.
– It often occurs in the long bones of the arms and legs at areas of rapid growth around the knees and shoulders of children.
– This cancer affects primarily children and young adults between the ages of 10 and 25.

Chondrosarcoma

– It is the second most common type of primary bone cancer.
– It develops in the cartilage tissue.
– It can be very aggressive or relatively slow-growing.
– It most commonly affects the bones of the pelvis and hips.
– It is found in mainly adults.

Ewing’s sarcoma

– It is a type of primary bone cancer that develops in the immature nerve tissue from the middle part of bones.
– The most common sites for this cancer are the pelvis, the chest wall (such as the ribs or shoulder blades), and the long bones of the legs or arms.
– It is more common in children and young adults.

Malignant fibrous histiocytoma

– It is a rare type of cancer.
– It occurs in soft tissues like ligaments, tendons, or muscles.
– This cancer most often occurs in elderly and middle-aged adults and is rare among children.
– MFH mostly tends to grow locally, but it can spread to distant sites.

Fibrosarcomas

– It develops more often in “soft tissues” than it does from bones.
– It is common in middle-aged adults and older people.
– It primarily affects the leg, arm and jaw bones.

Giant cell tumor of bone

– It has both benign and malignant tumors.
– It affects the leg (usually near the knees) or arm bones of young and middle-aged adults.

Rarer Bone Cancers

The following types of bone cancer are rare, and occur primarily in adults :
– Adamantinomas usually occur in the shinbone.
– Chordomas are found most often in the sacrum — the lower part of the spine, also known as the tailbone.
