POP,
I'm sorry to hear of the cancer. My mother in law (yes, I really do love her despite all my jokes about her) has been battling various types of cancer for about 10 years now. She still has a life, has maintained a life all that time, and so will you.
The one thing us guys do is avoid the doctor. You didn't, thankfully! We figure that we can battle through it and tough it out. But in this case you did the right thing, you sought help. It's not always easy to do all the time, but sometime it's the right thing to do.
I wish you all the best in your battle. You are in charge of you and not the disease. And I hope to hear ten days from now that you're cancer free.
Peace
Jerry
