bjs06, My heart goes out to you and your husband! I went through exactly the same thing as your husband 20 years ago! Identical with the lesions on the lung!
My experience with chemo was not good! a month after the tumor I started chemo. By the end of my first week I had a Giant Infection or reaction to the chemo drug, 5 FU & licovoron.
Two weeks later I was in the ER and given a couple hours to live! I was in a coma for 14 days in Intensive ICU with around the clock care. I spent another two weeks recovering after the coma!
With good care and understanding people I survived.
When I got out the doctor wanted me to go through chemo again.
My daughter and I said NO!
I changed me outlook on Life to defeat the disease! I spent the next year working out of my motor home traveling the Rockyy Mountain Area from Mexico to Canada!
That year I was on all or part of the day for 150 + days on trout rivers, streams and lakes flyfishing. Learning about Life!
Business wise it was the Best I had ever had!
Not to Brag but the cancer has never reacoured!
My point is the cure is in your mind and soul! You have to will it to be gone!
Your husband and you have your own decisions to make!
My thought is I would have the operation but leave it up to my mind to heal.
Maybe it was meant to be that I had that I had the reaction! I had to change my way I look at life and how I lived it!!
MY THOUGHTS, BLESSINGS, AND PRAYERS GO OUT TO YOU AND YOUR HUSBABAND!
