I think it’s more than reasonable to ask for one at 63.
I did it solely because I was 55 - I had meant to do it at 50 but kept putting it off. Anyway, I got a mini questionnaire to fill out on my phone. I answered it honestly but it was probably the “going to the toilet 3 or 4 times a night” that alerted them. Anyway, with my answers they asked me to come in for a test.
I understand that doctors say the PSA isn’t an ideal test, but my PSA was 23 when it should have been around 3, so I’d say it was an ideal indicator of cancer in my case. Note that a high PSA does not necessarily mean cancer.
Anyway, if you contact your doctor’s surgery, they will tell you what to do.
Hope it’s going OK for you in general. I accept the tiredness and hot sweats as part of the treatment. It’s certainly not a moan on my part. When you hear what some people have to put up with during treatment, this is a doddle, if a little uncomfortable :)
Best of luck to you to going forward. I think what this thread is showing is that plenty of people lead a relatively normal life post-cancer. I know it doesn’t always work out that way, but it is heartening to read everybody’s experiences.
