Cancer therapy isn’t just about hitting tumours harder; it’s about hitting the right spot, at the right time, with the least collateral damage.
In thuis episode Dr Gavin Nimon (Host) sits down with South Australian radiation oncologist Dr Vincent Pow to unpack how modern radiotherapy blends precision physics with genuine human care, guiding patients from referral to first beam with clarity and compassion.
We walk through the full treatment pathway—MDT referrals, planning CT, MRI and PET fusion, and meticulous contouring—before demystifying what happens on the machine.
Dr Pow explains why fractionation protects healthy tissue, how IMRT and VMAT shape dose around organs, and why today’s sessions feel more like a painless CT than a procedure. We dig into SABR’s rise in early lung and prostate cancer, and how targeted ablation is changing the outlook for oligometastatic disease by controlling spots in lung, liver, bone, and brain while delaying systemic escalation.
You’ll also hear a frank guide to side‑effects: what’s common, what’s rare, and how teams manage everything from cystitis and oesophagitis to fatigue and skin changes.
We explore adaptive radiotherapy—seeing tumours daily and adjusting dose on the fly—plus the growing role of AI in contouring and planning. Dr Pow shares why access matters, how telehealth and cancer lodges reduce travel for rural patients, and where education campaigns like Targeting Cancer help GPs and patients make informed choices.
This conversation brings the science down to earth without losing the nuance. Follow the show, share it with a colleague who needs a clean explainer, and leave a review with your biggest question about radiotherapy so we can tackle it next.
