Walking pneumonia led to lung nodule to lung mass! 2 biopsy this week

I had walking pneumonia over the summer. I went on antibiotics but scan showed rather large nodule and ground glass appearance. Biopsy was done and it was negative. This was in September. Then, I go for a follow up scan in early November and nodule, well, really, mass has gotten a tiny bit bigger, but ground glass appearance has cleared. The mass is the size of a business card! It's 4 cm by 8 cm! It was not really much different from the one in September but they want to biopsy it again. Will be doing that this week. I'm hoping it's still benign, but its size is so concerning. I do cough a little. That's really my only symptom. Lung surgery is really a major endeavor, but I don't don't what can be done except to hope it just goes away. With my history, I'm guessing it's infectious or inflammatory. I had a PET scan and it lit up, but so did a bump on my head that I got a week before the scan! Any advice?
