I guess as soon a possible, with me it was 2 weeks just enough time for them to come up with the a suitable plan for your treatment. However, in my case it took longer because the Onco wasn’t happy with the plan, it went through the ‘system’ a second time but he was still not happy. He was worried there was too much risk of collateral damage to my bowel if I had 37 session to include treating the whole pelvic area. Apparently my plumbing was in the wrong place! So it was a wait, followed by another ct Planning scan and then RT to just the Prostate and Seminal Vesicles.
Im not sure how often this happens but I’m glad my Onco spotted it and I didn’t end up with permanent bowel damage.
