What Could The Positive Nodule In The Lung Be?

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 HCM..
In my opinion you should definitely go for biopsy as it is the best investigation for lung mass.
Causes of PET positive lesions are
1. Malignant lesion.
2. Infective lesion like TB or fungal infection
3. 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.
