Ha ha ha - yes, that was John and one of his staff.
It is a little ignorant of friends not to ask how you are and I suspect that it is not limited to men and PCa. My friends that have undergone breast cancer treatment would probably say the same. Maybe it is because the general public view these days is that most cancers are curable - have the treatment, get over it and then get on with the rest of your life. There is an element of ignorance or lack of awareness of the psychological trauma of being told you have cancer but if you are honest, how much did you understand of that before you had to experience it yourself. If you look back, have you asked friends 2, 3, 5 years down the line how they are or have you assumed that because they are still alive they must be fine?
John sometimes mentions it in the pub, or makes a joke about ED or whatever. This does jolt his mates' memories and they will ask if he has been tested recently, etc. He also has friends that he sees less often but it is always the first thing they ask - how are you, are you still clear, is everything okay? But these are 'professionals' (a Professor at the local hospital pathology service, a nurse, a friend whose dad died young due to PCa and so on) and to be honest, my female friends are much better at asking than his male friends are.
