Hello Amarone Lover and welcome to the site.
Sad that you find yourself here, but with no symptoms to speak of it was lucky you had the routine health check.
It isn't at all odd that you should feel better and less like a Zombie than you did. A lot of people on here, men and their wives and partners like me, will tell you that the waiting, the wondering, the fear and the "what ifs" are possibly harder to take than the knowledge that you do, in fact, have cancer.
You want the thing out and have made your decision. There are also people on here that will definitely agree with you that the dead don't have sex and life is more important. We each make our choices according to what we hope and pray will be the right one but whatever happens in the future, this is your choice and hopefully it will all work out right for you.
Glad you found us, even if the reasons are pretty naff!!
All the best
Sandra
