Hi, new to this group. My husband had surgery for tongue cancer 5 weeks ago. As he is also in AF it was decided not to remove his lymph nodes. On Thursday we had a follow up appointment and was told at a recent ct scan they found a nodul on one of his lungs which they want to keep an eye on. The doctor said it was very small but he has been booked in for another scan at the end of this month. We are both worried sick. This news took us both by surprise and we didn’t ask any questions. I am wondering what a nodule is and do they suspect cancer in the lung? The cancer on his tongue was 8mm and not too deep and has all been removed. Could this have traveled to his lung? Thank you
