Only cells that make bone are able to cause Bone Cancer. More than two-thousand individuals are diagnosed in the U.S. every year with a bone tumor. Bone tumors take place most usually in youngsters and adolescents and are less common in older adults. Cancer involving the bone in older grownups is most commonly the effect of metastatic spread from some other tumor.
There are many various types of bone cancer. The most ordinary bone tumors include osteosarcoma, Ewing’s sarcoma, chondrosarcoma, malignant fibrous histiocytoma, fibrosarcoma, and chordoma.
Osteosarcoma is the most ordinary primary malignant bone cancer. It normally hits males between 10 and 25 years old, but can it can’t affect the most older adults. It often happens in the long bones of the arms and legs at places of quick growth around the knees and shoulders of children. This type of cancer is often very aggressive with risk of spread to the lungs. The survival rate of five year is 65%.
Ewing’s sarcoma is the most aggressive bone tumor and affects younger people between 4-15 years of age. It is more common in males and is very rare in people over 30 years old. It most commonly occurs in the centre of the long bones of the arms and legs. The three-year survival rate is about 65%, but this rate is much lower if there has been spread to the lungs or other tissues of the body.
The second most common bone tumor is Chondrosarcoma and accounts for about 25% of all malignant bone tumors. These tumors arise from the gristle cells and can either be very aggressive or relatively slow-growing. Unlike many other bone tumors, chondrosarcoma is most common in individuals over 40 years old. It is somewhat more common in male people and can potentially spread to the lungs and lymph nodes. Chondrosracoma most commonly affects the bones of the pelvis and hips. For the aggressive form is the survival rate about 30%. The rate for slow growing tumors is 90%..
Malignant fibrous histiocytoma (MFH) affects the soft tissues including muscle, ligaments, tendons, and fat. It is the most common soft-tissue malignancy in later adult life, usually happening in people 50-60 years of age. It most commonly affects the extremities and is about twice as common in males as females. MFH also has a wide range of severity. The overall five-year survival rate is about 35%-60%.
Fibrosarcoma is much more rare than the other bone tumors. It is most common in people 35-55 years of age. It most commonly strikes the soft tissues of the leg behind the knee. It is slightly more common in males than females.
Chordoma is a very special tumor with an standard survival of about six years after diagnosis. It takes place in adults over 30 years of age and is about twice as common in males as females. It most commonly affects either the lower or upper end of the spinal column.
In addition to bone cancer, there are different types of benign bone tumors. These include osteoid osteoma, osteoblastoma, osteochondroma, enchondroma, chondromyxoid fibroma, and giant cell tumor (which has the potential to become cancerous). As with other types of benign tumors, these are not cancerous.
Lymphoma and multiple myeloma are two other relatively common types of cancer that develop in the bones. Lymphoma, a cancer arising from the cells of the immune system, usually begins in the lymph nodes but can begin in the bone. Multiple myeloma begins in the bones, but it is not usually considered a bone tumor because it is a tumor of the bone marrow cells and not of the bone cells.
