How many treatment sessions will I need?

The number of sessions can vary based on the specific tumor and protocol, but generally on the order of 15 to 25 sessions are needed in total for IG-SRT. A typical course is often around 20 treatments. In clinical practice, this is usually translated to something like 3–5 sessions per week over about 4–7 weeks. For instance, one common regimen is 5 treatments per week for 4 weeks (total ~20 treatments), or 3 treatments per week for 6 or 7 weeks (total ~18–21 treatments) – either approach can yield around the same total sessions and dose. The exact number will be determined by the treating physician’s protocol for your cancer’s size and type. Larger or thicker tumors might be on the higher end of sessions, whereas very small superficial ones on the lower end. It’s important to complete the full prescribed number of sessions to achieve the highest cure rate. The good news is each session is short, and the cumulative effect of these multiple sessions is what destroys the cancer completely.
