A long post - hope it isn't telling you more than you want to know!
I was on hormone therapy for about 7 months (last 3-month injection was September 2019), then started radiotherapy October 16th. The preparation before and during the course of r/t is a bit of a faff - 'planning meeting', where they scan you, take measurements and put 3 small tattoos (dots) on you. For each 'fraction' (dose of radiation) you must have an empty bowel (strong laxative suppositories before each visit) and a full bladder, which means you have to arrive at the hospital around 45 minutes - one hour before your treatment time. Once there you will have to drink about 500 ml of water / squash, then wait for this to reach your bladder. It's important that you are already well hydrated, otherwise it won't get to your bladder but will be absorbed into your tissues, so you must drink around 2 litres of water per day during your treatment. Once in the treatment room (it's sometimes called a 'linac' - linear accelerator) you will be positioned on the table, and the radiographers will move you about until the 3 tattoo dots line up. Then they leave, and the machine starts. It will scan you so they can check your bowel and bladder. The actual dose of radiaton only lasts about 2 minutes, and you are unaware of it, but the machine will move around you a few times. Then the radiographers come back in, help you off the table, you rearrange your clothing then walk steadily to the nearest toilet! You will have either 20 or 37 fractions, Monday - Friday with weekends off. There will be few (if any) side effects at first - these will develop over the duration of your treatment. Oddly, they actually get worse in the 2 weeks after your treatment is over, but are manageable. After 8 - 10 weeks they should pass altogether. So, r/t is a bit of a faff, but doesn't hurt. The side effects can be unpleasant, but not unbearable, and not long-lasting. Six months after my treatment ended, I had my first post-treatment PSA test - less than 0.03, if memory serves! If you don't already have it I suggest you download or order the 'Prostate Cancer Tool Kit' from Prostate Cancer UK. It will tell you evrything you want to know, and more! Also, you should have an assigned specialist nurse who can take your phone calls, or you can call the Prostate Cancer UK specialist nurses if anything is worrying you. My overall impression, from being diagnosed to finishing my treatment, was that I was on a really slick smooth system for helping prostate cancer patients. Best of luck with your treatment.
