[|Human|] Hi, I am a 52 year old female nonsmoker who went in for a free Heart EBT Scan and they saw a 7mm nodule on my right lung.  My doctor said to followup with a CT scan in 90days or so. I did and it said I had a 1.7CM nodule.  I have absolutely no symptoms, not around 2nd hand smoke, do not smoke and no radon in house.  They now want me to have a PET Scan which I am very hesitant about jumping into.  I am beginning to question both the dr and radiologist. I live in Las Vegas and everyone knows the drs here are the worst and very untrustworthy.  What do you recommend for me to do?  Thanks
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Smoking is known cause for lung cancer. But it is not the only cause.Non-smokers after the age of 50 years are also at risk of lung cancer. Your lung nodule is increasing in size from 7 mm to 1.7 cm in 3 months. This is said to be rapidly growing. So possibility of malignant lung nodule is very high. PET scan is more informative than CT for cancers. So get done PET scan. If it is malignant then lobectomy is advisable. And believe me, lobectomy in early lung cancer has excellent results, near normal life. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
