Hello Andrew,
I had HDR Brachytherapy in August 2014, followed up by 15 sessions of radiotherapy. Before the Brachytherapy I was on Bicalutamide for 3 months, and I am still on Bicalutamide for a few more weeks.
Two days after the Brachytherapy I felt ok and overdid it a bit, but I was soon bored and started work again (desk based) and after a week was back to what I felt was normal. So for me the Brachytherapy itself wasn't the hard part.
The Bicalutamide has side effects and I have had some, but not as bad as I think some have them. Gynaecomastia is managed by Tamoxifen, and weight gain by diet. Overall I gained about 4 kilos, but now it is warmer that is coming back down.
I only had a couple of hot flushes, my body hair has largely disappeared in the past 6 months, though I have more and darker hair on my head. I am getting more tired at present but that is a recent thing and may be related to work etc.
Now it is warmer I will do more walking, last summer I was walking 10 to 15 miles a day.
The radiotherapy was a drag, having to go in to the clinic every weekday. However I didn't suffer from it as much as the chap who had his appointment after me, he struggled.
Along the way I have had a couple of UTIs, they were resolved with the usual antibiotics. More recently some blood in my urine and pain on urination. My Urologist prescribed Avodart (Dutasteride) and that sorted those out in a couple of weeks. As part of that I had a cystoscopy and apparently I have some radiation scarring.
I have been taking Tamsulosin and am working on reducing that progressively. Initially on the days I didn't take it, it was a bit of a struggle and I get the occasional "bad day" but nothing drastic. I make cranberry juice and drink a cup of that every morning and that seems to help. I haven't had a UTI since doing that (the supermarket cranberry juice is a waste of time).
So overall I think I have had a relatively easy time of it compared to others. Every cancer and every patient is unique so no one can tell you now what it will be like for you, only what it has been like for Alan and Pierre.
The big differences I think you can make are to get fitter before the procedure, read up and be prepared, make sure your loved ones are aware of what the changes might be.
I hope it goes well for you
Regards
Pierre
