The radio therapy might be a bit daunting, but actually it isn't. The machines which do the job ('linac', or linear accelerator) look a bit like a scanner. You lie on the table, and the radiologists leave the room after they have moved you around into the righr position. You will have 3 small tattoos which are used to locate you properly. Don't worry - there is a camera on you all the time, so if you have any problems, help is at hand. The machine does an initial scan to make sure all is as it needs to be. If it is, the actual treatment only takes a couple of minutes. The machine will rotate around you, stopping and starting, so that the beam hits your cancer from different angles. It is completely painless.. Once it is over, the technicians come back in and help you off the table. You can go home (usually via the toilet to empty your bladder, which has to be full before treatment can start!). The side effects vary, and don't usually start until a couple of weeks into the treatment. Actually they peak a couple of weeks after your final go in the machine, then gradualy get better. Apart from fatigue, I needed to be careful with my bowels (sudden urge to go!) and the very common 'mucous farts', but there is treatment available for those.
I finished my radiotherapy 15 months ago. Today, I had a telephone consultation and was told that my PSA is now 0.05 (it was 0.04 six months ago). Virtually the same (allowing for testing error). My onco team is very pleased and will ask for another PSA test in August.
I still have some side effects from the hormone therapy, but they too are reducing. The 4 weeks (4x 5 days per week) are a bit of a faff, but you can plan around them. I opted for treatments early in the day, so I was usually home by 10:00. Hope yours go as smoothly as mine did.
