Good morning Amy and welcome to Mayo Clinic Connect. I'm sure that this was a huge shock to you since you have never smoked. Hearing that you have cancer is a blow all by itself. I was 51 when I was first diagnosed and it is now 24+ years later. My cancer is different than yours.

Cancer has its own timetable, waiting to be the norm, your time is best spent doing exactly what you are doing. Exercise, but make sure that you walk when you get out of breath or begin coughing. Are you bringing up any blood?

Clean eating is the best and keeping busy until your next appointment. Have you had any bloodwork as yet? Other than a CT have you had an MRI or PET scan?
