Cancer treatment has a reputation for being slow — weeks of daily appointments, cumulative side effects, and a plan that doesn't change once it's set. Adaptive radiotherapy, offered at 5D Cancer Services in St. George, works differently.
What makes it different
Conventional radiation therapy uses a single treatment plan mapped out before your first session and delivered the same way over 20 to 45 sessions. The problem: your body changes daily. Tumors shift, shrink, and move as treatment progresses, but a conventional plan doesn't adjust for that.
Adaptive radiotherapy re-images and re-plans your treatment at every single session. That means the radiation team is working from a current, high-resolution picture of your anatomy each time you're on the table — not a snapshot from weeks earlier.
Why that matters
- Sub-millimeter precision. Daily re-planning allows smaller treatment margins, so radiation targets the tumor itself rather than a wider area of healthy tissue around it.
- Weeks faster. Higher precision allows higher, safer doses per session. Many treatments are completed in as few as 5 days, instead of the 4 to 9 weeks conventional radiation typically takes.
- Fewer side effects. Because more healthy tissue is protected at every session, clinical trials show significantly fewer long-term side effects compared to conventional treatment plans.
Guided by A.I.M.
Three principles drive every treatment decision at 5D Cancer Services:
- Adaptation — replanning treatment daily to match your anatomy as it is today, not as it was at the start.
- Imaging — high-resolution real-time imaging before every session for a precise, current picture of the tumor.
- Margins — tighter margins made possible by daily imaging, protecting more healthy tissue with every dose.
