What you should know about bone cancer
- Most primary bone cancers are sarcomas.
- A sarcoma is a cancer that begins in the cells that make up the supporting tissues of your body. For example, your bone, muscle, cartilage and ligaments.
- The cause of primary bone cancer is unknown. Your risk of developing it increases if you have had previous cancer treatment, certain genetic conditions or bone diseases.
- The main symptoms of primary bone cancer are pain, swelling, difficulty moving a joint, a limp, weak or numb limbs, and bone fractures (breaks).
- Primary bone cancer is diagnosed by X-rays, bone scans, biopsy and MRI scan.
- Treatments for primary bone cancer can include surgery, chemotherapy or radiotherapy.
What are the bones?
Your bones are rigid tissues that make up your skeleton. They help you to move and support and protect the organs in your body. They also store minerals and make red and white blood cells in your bone marrow. As an adult, you have over 260 bones of different shapes and sizes.
