ALL radiation increases the chance of cancer developing...Radiation used to treat cancer is no different..That's why radiation therapists and x-ray technicians go to such great lengths to avoid accidental or unnecessary exposure..The early researchers in radioactive materials suffered horrendous injuries and increased cancer rates..
Proton radiation damages all the tissue it strikes, be it cancerous or healthy..The advantage is it strikes less tissue outside the target area so less healthy tissue is damaged.. There is no exit path with protons..
It's a risk / benefit thing...When you are fighting a potentially terminal illness and the treatment (radiation) ads a 3% higher risk of developing a radiation caused cancer later on, most people are willing to accept that risk..Nobody forces anybody to have radiation treatment or any other treatment..
With RT, the primary risk is the direct damage to healthy tissue not secondary cancers..When my SRT was being planned, a dose of 80 Grey was talked about..By using the latest equipment and trying as hard as he could, my radiation oncologist thought this was possible and safe. But he cut his plan back to 72 Gy when the risk-benefit equation could not be worked out and 80Gy was deemed too dangerous to try..
