[|Human|] I am very worried anout upcoming luing surgery. I m 54 year old woman with a 8mm nodule at base of rt lung. This was found by accident. However, apparetnly this lung nodule was present in a previous film in 2010 at 5mm but the dr never told me. The radiologist said on report it was benign. I had a pet scan that showed suv of 2.2. Im convinced its cancer. What is the percentage that it is. Also pet scan done on entire body and nothing was found excpet for that nodile.
[|AI|]  Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. Following are the possible causes for lung nodule. 1. Benign cyst2. Fibrotic or calcified spot3. Initial stage of infective granuloma4. Very early lung cancer. If you are smoker then possibility of malignant nodule is high. In 8 mm nodule we can not do biopsy or any other diagnostic test. The only option is to wait and watch. Get done repeat CT thorax after 6 months to know whether nodule is static or decreasing or increasing in size. And if you are smoker then quit smoking as soon as possible.
