Can time of year Affect PSA?

Thank you Lyn, In retrospect, I suppose we are more active in the summer months. It's possible this activity level could have a bearing on our PSA. Only wish I was up to really taking advantage of the summer months like John or I would settle for being able to play tennis again. Unfortunately, arthritic knees now restrict me to a modest walking pace and shorter distance. Notwithstanding any possible increase in PSA, I intend to start swimming sessions throughout the year, as I feel a healthy and exercised body should be able to cope better with cancer and many other potential health problems. It can take more effort in wintry conditions though.

I am sure we all wish it works out well for John and he is able to indulge again in his cycling and other pursuits. You will be aware that knee replacements are more tricky and the outcomes less overall positive than for hip replacements. My knees were assessed and it was decided that implants could be deferred for the time being. I was just given physiotherapy and exercise sessions which I found hard going and not repeated to the extent that I should have done at home thereafter. I suppose John will have to adopt some rehabilitation exercise programme.
