Radiotherapy uses targeted doses of radiation therapy to destroy cancer cells and shrink tumors. You may hear your doctor recommend radiation therapy if you or someone you care for faces cancer. More than half of patients worldwide need radiotherapy as part of their treatment, especially for cancers like breast, lung, and prostate. Advanced radiation therapy techniques deliver high local control and survival rates with fewer side effects.

Radiotherapy for prostate cancer usually takes between 5 days and 9 weeks, depending on the type of treatment chosen. Most patients attend about 45 sessions, with each session lasting around 10 to 60 minutes. Recent advances in radiation therapy, such as hypofractionated schedules, allow some men to finish their treatment in as few as 5 sessions over 1 to 2 weeks. The number of sessions and duration can vary, but medical teams use modern techniques to ensure patient comfort and make the process manageable.

Most patients spend about 30 to 60 minutes on a CT simulation, with some sessions taking up to 90 minutes for complex cases. The process remains straightforward and centers on patient comfort. CT simulation serves as a crucial step before radiation therapy. Staff use advanced equipment and clear instructions to help patients feel at ease throughout the session.
