Radiation therapy is used mainly as treatment for many different types of cancer. Radiation therapy is used to slow or stop the growth of cancer cells. Radiation uses high-energy X-rays to damage the cancer cells and prevent them from multiplying. In many cases, it can destroy a cancer tumor. Radiation may be used alone or in combination with surgery or chemotherapy. Additionally, radiation may be used to treat other medical conditions, such as epilepsy, Parkinson’s Disease, and arteriovenous malformations. State-of-the-art technology has advanced radiation methods to help make them more effective and tolerable than they were in the past.
How Radiation Therapy Works
With SRS and SRT, sophisticated software controls the radiation treatment beams to match the exact shape of a tumor or lesion. The beams may be moved to penetrate the cancer from different angles. This precision delivery method quickly allows the cancer to receive the full dose of radiation, while the surrounding healthy tissue only receives a small percentage of radiation.
Brachytherapy- Intracavity and Interstitial
Brachytherapy is used to destroy cancer cells using an internal source of radiation. Radiation from internally placed radioactive seeds disrupts the growth of cancer cells. Brachytherapy spares as many healthy cells as possible because it directs radiation to only a specific area. Brachytherapy is used as a treatment for many types of cancer, including sarcomas, prostate, breast, lung, gynecological, head and neck, and colorectal cancers.
The experience of cancer and cancer treatments can be a very emotional experience for you and your loved ones. It is important to embrace positive sources of support. Some people find comfort in their families, friends, co-workers, counselors, and faith. Cancer support groups are a helpful resource where you can receive support, information, and understanding from people with similar experiences. Ask your doctor for support groups near you.
