When I was diagnosed / treated back in 2019 (six months of hormone therapy then 20 sessions of radiotherapy). at the 'planning meeting' the biggest shock was to get 3 little blue tattoos - one on each hip and one on my pubis! Aiming marks, apparently, for when the rt treatmant starts. I still have them - like a badge of pride! Before you go in for the rt appointments, make sure that you are well hydrated- drink water steadily throughout the day. If you don't, the water you drink just before the rt session will not go into your bladder, but into your tissues, and the radiographers will send you out if the treatment room to get 'filled up'. Once you are lined up on the table, the machine will hum and spin around a bit while they do a scan. The 'treatment phase' is quick - maybe about a minute - to me it sounded like a mosquito was in the room. You are lying on a machine which cost the thick end of a million quid - I was fascinated by it!
