My dad is 63 and has never smoked and is generally in good health. He has had a cough for a few months and has been back and forth to the doctors, resulting in him having a ct scan, the result of which he's had today. There is a 6mm anomaly on his trachea, and he now has to have a camera down to have a look. I'm so worried. When I Google it the only thing that comes back is cancer. I'm really hoping someone might have another idea of what this could be.
