Went for a c t scan last month after having a cough for a while, which I still have gotand they found 3 subplueral lung nodules 4mm in the right upper lobe 6mm in the right middle lobe 6mm in the left lower lobe I am a 51 year old female and a non smoker I received a letter this morning to go back in 12 months time. But my doctor said it would be a 3 months check up then to 6 months for 2 years. So now I am worried it seem a long time to wait
