It's all a risk, isn't it though - men who choose radical treatment hoping for a cure but then discover that they need adjuvant or salvage treatment, men who choose one option based on minimising potential side effects only to find they are really unlucky, men who opt for AS and are then let down by a medic that really does nothing more than watchful waiting.
Stan took a risk opting for AS and was unlucky that his PSA did not behave in the expected way. Dad is taking a risk in refusing salvage treatment. I can't say I always feel happy about it but I do understand that both had the right to make their own decision regardless of what I think or want :-(
