Groundglass Opacities in Upper Right Lobe & Family History of Lung Cancer

62 year-old, non-smoker, male. Had a shoulder replacement scheduled. A CT scan was done as part of the pre-surgical prep. The CT showed an incidental finding of multiple groundglass opacities in right lung. Subsequent x-ray confirmed findings. Worried because groundglass opacities were found once in my Mom's lung, and the doctor chose "watchful waiting." It ended up being cancer, and she lost her right lung. (But she lived.) I also had an uncle die of lung cancer. Because of my family history, I'm concerned. Here's the radiology report:

"The group of mixed solid and groundglass nodules in the right upper lobe now have a slightly more solid central component but are otherwise unchanged in number. They are 10 mm and under in size. Calcified granuloma right lower lobe."

Radiologist recommended a second scan in two months. In the meantime, I received a pulmonary referral from my primary care provider, but can't get an appointment for 3 months. I also learned that my C-Pap machine had been recalled because 561 people had died from particles that were pumped into their lungs.

I'd really like to have this investigated immediately. Because of the size, the fact that they now appear to be more solid, and the C-Pap recall, I'm worried about this. Does anyone have any opinions? How urgent is this?
