What is the meaning of numerous small bilateral pulmonary nodules?

"Numerous" means "lots of". "Small" means ... well, small. "Bilateral" means "on both sides". "Pulmonary" means "having to do with the lungs". "Nodules" are swellings or lumps.

That's assuming you just wanted it translated into simpler English. If you meant "how does this impact my chances of living to see Christmas", talk to your physician, because that depends on what the nodules are and what's causing them.
