Types of Bone
on its characteristic, bone cancer is classed in different types: osteosarcoma, chondrosarcoma, Kaposi's sarcoma
and multiple myeloma.
osteosarcoma is the most common type of primary bone cancer, affecting mostly children and adolescents or young
adults. Most of the times, the tumor
develop in the
extremities (metaphyses) of the long bones located near the joint of the knees (femur, tibia) and shoulder
(humerus). In general, osteosarcoma is characterized by persistent pain and swelling.
this is a malignant bone tumor that develops mainly from cartilage. Although it can develop in any bone of the
body, chondrosarcoma mostly begins in the hip, pelvis and in rare cases the leg or arm: metaphysis and
diaphysis. Chondrosarcoma is the
second most frequent primary bone cancer. It is more common among
adults aged 30 and over. Chondrosarcoma is characterized by bone pain and a solid mass on palpation.
Sarcoma - Ewing's
sarcoma occurs when there is a proliferation of small round cells born in the central region of the bone. Ewing
sarcoma is a very rare form of bone cancer, affecting about 2 to 3 people per million. The tumor affects mostly
children between 10 and 15 years, with a prevalence among males of the white race. Ewing sarcoma affects mostly
short or flat bones: pelvis, ribs, vertebrae; and long bones: femur, fibula, tibia, and humerus. Ewing's sarcoma
is characterized by persistent pain, swelling and sometimes fracture.
also called Kahler's
disease or multiple
myeloma, myeloma develops from cells of hematopoietic stem cells, multipotent stem cells that are
responsible for producing blood cells in the bone marrow. Myeloma is characterized by a malignant proliferation
of cells in the bone marrow that are responsible for producing and excreting antibodies in the blood serum
(plasma). The proliferation of these (cancer) cells causes a progressive destruction of bone tissue. Unlike many
other types of bone cancer, myeloma is more common among adults between 50 and 80 years with a prevalence in
men. Usually, multiple myeloma results in pain and spontaneous fractures of the long bones.
