what is the success rate of radiation therapy

The success rate of radiation therapy varies depending on the type of cancer being treated and the stage of the cancer. According to a study published on PubMed, the overall 5-year survival rate for radiation therapy patients was 27% . However, radiation therapy has been found to be effective in treating prostate cancer, with a cure rate of 95.5% for intermediate-risk prostate cancer and 91.3% for high-risk prostate cancer. Another article from Oregon Cancer Center states that radiation therapy is useful for about 60% of all cancers. The success rate of radiation therapy has improved over time due to new treatment methods and updates to the amount of radiation given. The specific number of treatments depends on the cancers location, its size, and each patient’s general health. In addition, new technological advances in radiation therapy have made treatments more effective and precise. Overall, radiation therapy contributes to 40% of all cancer cures worldwide and is a cost-effective cancer treatment.
