[|Human|] I am 39 years old and just found out yesterday that a CXR I had last week showed a pulmonary nodule.  I am a 3/4 to 1 ppd smoker with a history of persistently elevated WBCs, fibromyalgia, and hypothyroidism.  Is it probable that I have an early lung CA?  My MGF is deceased from lung CA and PGF deceased from stomach and esophageal CA.  Both were smokers.  Thank you for your input.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you should consult pulmonologist and get done CT thorax with Contrast to know the characteristics of nodule because you are at high risk for malignant nodule. You are smoker and having positive family history for cancer. So get done CT thorax with Contrast. CT will tell you about exact size, shape, structure of nodule. CT will also tell about association with surrounding lung structure, mediastinal lymphadenopathy etc. All these points are important in differentiating between benign and malignant nodule. If it is benign lesion then no need to worry. But if it is malignant looking nodule then biopsy is needed for confirmation. In any case, better to quit smoking as soon as possible. So consult pulmonologist and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
