Osteosarcoma

Osteosarcoma

Osteosarcoma is a type of bone cancer that develops in the osteoid tissue of bones. It is most commonly found in the long bones around the knee, but it can occur in any bone. Osteosarcoma is typically found in children and young adults.

Causes and Risk Factors

The exact cause of osteosarcoma is not known, but several risk factors may increase the likelihood of developing this type of cancer, including genetic predisposition, certain inherited conditions, and previous radiation therapy.

Symptoms

Common symptoms of osteosarcoma include pain, swelling, and sometimes a noticeable mass near the affected bone. Pain may worsen at night or with physical activity.

Diagnosis

Diagnosis usually involves imaging tests such as X-rays, CT scans, or MRI scans, followed by a biopsy to confirm the presence of cancerous cells.

Treatment

Treatment for osteosarcoma typically involves a combination of surgery to remove the tumor and chemotherapy to kill any remaining cancer cells. Radiation therapy may also be used in some cases.
