I will let you know more about this next week after my CT scan....I had bronchoscopies and biopsies when first diagnosed and I am not sure why I had so many different diagnostic procedures (3 growths back then...) but I think one of the nodules then (as now) was somewhere on my right lung. It was not cancer then. I hope you are working with a cancer facility like Mayo, Moffitt (me), MD Anderson, Sloan Kettering. Good luck to us both.
