Ct-scan report of 2 noncalcified nodules in the upper lobe of my right lung. should i still be cleared to have arthroscopic knee surgery next wk?

Probably : These are chronic, and shouldn't cause cancellation of your knee surgery. They do need to be followed, or compared to old X-rays if available to ensure stability. May also need a ct scan at some point. Ask your primary care to follow up with this and recommend a course of action after your knee is fixed. Hope this helps! And good luck with the operation!
