In 2008 I had my TT. I currently take Armour but I don't think I am on a high enough dosage. Can't get doctor to raise dose. About six weeks ago I was diagnosed with lung cancer. Had the lower right lobe of my lung removed. My question is, I am trying to eat healthy and going to start exercising as soon as I get the okay. What foods should I be trying to avoid? Should I stay away from iodine? Do I avoid cruciferous vegetables ie. broccoli, kale and Brussels sprouts?
