(Cartilage Cancer; Cancer of the Cartilage)

Chondrosarcoma is a type of cancer. It grows in cartilage cells in the body. Cartilage is connective tissue.
This cancer is typically found in the cartilage cells of the femur, arm, pelvis, knee, and spine. Rarely, the ribs and other areas may also be affected.
Cancer occurs when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This is called a growth or tumor. The term cancer refers to malignant tumors. They can invade nearby tissue and spread to other parts of the body.
The cause of this cancer is not fully known. Some cases may be due to genetics.
Certain factors seem to be common among individuals who develop chondrosarcoma. These include:
- Enchondroma—a non-cancerous bone tumor often found in the hands
- Osteochondroma —excess cartilage or bone found at the end of a growth plate
- Multiple osteochondromas—bone tumors
- Ollier's disease, which causes a group of enchondromas
- Maffucci's syndrome, which causes a combination of multiple endochondromas and various tumors
The most common symptoms of chondrosarcoma include:
- Large lump or mass on a bone
- Pressure surrounding the mass
- Pain that worsens at night
- Pain that does not improve with rest
- Pain that gradually worsens over time and may last for years

Treatment can vary based on your age, overall health, and stage of the disease. Talk with your doctor about the best plan for you. Treatment options include:
Surgery is the most effective way to remove the tumor. It is more effective than chemotherapy and radiation. Physical therapy may be used to help the area heal after surgery.
High energy x-rays may be used to target and kill cancer cells.
Drugs that kill tumor cells may be used. The use of chemotherapy may depend on the type of chondrosarcoma that you have.
The cause of chondrosarcoma is not fully understood. There are no known preventive steps for this condition.
