Arthur, I sincerely hope you continue to do well notwithstanding your PSA beginning to rise. Unfortunately, we have had men on this forum with low PSA after HT/RT for ten years or longer who had apparently beaten this rotten decease, then only to find their PSA had began to rise at an increasing rate and need to resume HT and other treatment. To the best of my recollection Barry Barrington (Topgun) was one of them and sadly we lost this well loved member, So be positive but don't take anything for granted.
As I said previously, I also wish our member in Canada well. HT/RT can restrain the cancer for many years and for some provide a 'cure' or sufficiently control it until they die of something else, although sometimes further down the line treatment(s) can be required. I took it that we were being asked would the proposed HT/RT treatment eradicate the cancer and I answered based on what I was told as stated. I now understand the OP meant something slightly different. Particularly when it comes to HT, men are affected to varying and greater or lesser extent. Some suffer some or all of the typical effects such as premature tiredness, muscle aches, hot flushes., sensitive nipples and increase in breast size and even personality changes. One of the most common effects is lack of libido but we did have one member who told as this was not a problem in his case. RT can add to side effects of HT although most men tolerate it well. In the UK it is now quite usual to continue with HT after RT for anything up to 3 years and beyond that if PSA so indicates. A man with PCa is on a journey with a road that can be tough at times for some whilst others cope better. There are now many ways to treat which can extend the life of a man albeit with other side effects. Trying to keep fit helps with coping.
