Hi,
Congratulations on your good health! It sounds like your procedures worked out well. It's hard to decide what to do when you are facing issues such as you are. My husband had lung cancer and due to almost dying from the side effects of Keytruda he elected to have no more treatments. We had 14 more years together with him having lung cancer. He's in Heaven now and I know we'll eventually be together again.

81 is not young. You might just want to enjoy your life while you have it. I would suggest taking your situation up with God. He's the one in control of life and death anyway. Just talk to him like he's your best friend and he is! He made you and he can fix you! I'll say a prayer for you also.
I wish you the best.
