Bone cancer treatment with radiotherapy
- Use in Radiotherapy high-energy rays or particles to kill cancer cells. The rays are directed to the body and focus on cancer.
- Most bone cancers are not easily destroyed by radiation and need to use high doses. Higher doses may damage healthy structures in nearby areas such as nerves. Therefore, radiotherapy does not play a significant role in treating most types of bone tumors, except Ewing’s tumors.
Radiation therapy reduces the size of tumors by using high doses of X-rays. Radiation is often used before surgery to shrink the tumor so that it reduces the amount of tissue that needs to be removed. Radiotherapy is used in a different case:
- Radiotherapy may be used after surgery to eliminate cancer cells that remained at the edges of the tissue after the tumor was removed.
- It is also used to treat bone cancer that cannot be completely removed by surgery; To help control tumor growth, and to relieve symptoms of bone cancer such as pain and swelling.
