I have a PET positive nodule (mass) in my upper right lung. My doctor said it is about the size of a golf ball. I am having a biopsy this week. I had a 7 day round of levicor (?) antibiotic. I am very concerned it is cancer. Waiting for a biopsy is causing more anxiety. What are your thoughts.
Thanks for your question on Chat Doctor. In my opinion you should definitely go for biopsy as it is the best investigation for lung mass. Causes of PET positive lesions are1. Malignant lesion.2. Infective lesion like TB or fungal infection3. Inflammatory nodule. So to rule out this biopsy is needed. The size of your lesion is quite big, so chances of malignancy are high. So get done biopsy.
