I have had a mass on my right lung for over a year now without any doctor telling me what this could be . I have chest pain all the time, pain in my stomach , to tired to do daily activities. I have had a pet scan done and it showed this wasnt cancer it was not hardly active at all what could this be?
Thanks for your question on Chat Doctor. I can understand your concern. I still think about lung cancer for this mass. PET scan is not always accurate for malignancy. Some lung cancers don't show any uptake on PET scan. So negative PET scan does not always rule out malignancy. In my opinion, you should definitely get done lung biopsy from mass. If this is negative for cancer then no need to worry about lung cancer. Negative lung biopsy is sufficient to declare it benign mass. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
