Definition

Chondrosarcoma is a type of cancer. It grows in cartilage cells in the body. Cartilage is the connective tissue. Most bones are created from cartilage.

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.

Causes

The cause of this cancer is not fully known. Some cases may be due to genetics.

Risk Factors

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

Symptoms

Symptoms will vary from person to person. The location and severity of the tumor will affect them. 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 responds to anti-inflammatory pain relievers
• Pain that does not improve with rest
• Pain that gradually worsens over time and may last for years

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done.

Tests may include the following:

• You may need tests of your bodily fluids and tissue. This can be done with:
  • Biopsy
  • Blood tests
• You may need to have pictures taken of your bodily structures. This can be done with:
  • X-ray
  • CT scan
  • MRI scan
• You may need to have your tissue function tested. This can be done with a PET/CT scan.

Treatment

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 may be used to remove the tumor. Physical therapy may be used to help the area heal after surgery.

Prevention

The cause of chondrosarcoma is not fully understood. There are no known preventive steps for this condition.
