Sorry to see you and your husband have got to go through the journey of prostate cancer, I was diagnosed in 2017 low risk Gleason 6, grade 1 T2a confined.
I went on active surveillance for 3years no treatment, apart from 3 biopsies, 3 mri, 1 bone scan, I was fine with 2 of the biopsies, but the last one I had an infection in hospital overnight then it cleared up.
The decision which treatment to have RT or Surgery is something I I though about and researched for 3 years.
I decided to go for surgery, albeit RT gives the same success rate you need to read all the information for both which is available from the site, they will post all the information out to you.
Given your husband is a builder self employed? you may think surgery would take longer to deal with, this is not necessarily correct, before RT you have hormone therapy and this goes on after for a further 3 months, and RT you attend the hospital 5 days a week for 4 weeks this is the minimum time some are longer.
Surgery in one day out the next, yes a catheter for 7to 10days, no drugs apart from paracetamol for a few days.
I had surgery the 25th November 2020 everything went fine took it easy for a month, plenty of walking, in the new year started light exercise weights, by end of February fully up to speed and riding my bike again and lifting weights prior to op, I am 68years old fit retired but I can now do everything before I had surgery gardening digging no problem.
We are all different I have had a great recovery I was fit before that helps of course, good luck to both of you which ever you choose, if you go for RT surgery is not really possible if required in the future, but RT can be a salvage treatment if ever required after surgery, take care.
