Can anybody answer these questions Dr.'s are confused.

Hello, I have a question I hope somebody might be able to answer. A bad TBI the end of 2004 with some of these symptoms, but has gotten increasingly worse. Now as of Febuary 2007 the nodules have shown up. If you have one pulmonary nodule in the left lung, then 6 months later you have one pulmonary nodule show up in the right lung (so one in each lung) could cancer happen that way, or do you have to have multiple nodules in one lung before it spreads to the next lung? Could you have nodules that aren't showing up on CT yet? Also thickening and lung scarring. What if there is a suspicion of Cerebellar Degenerative Paraneoplastic syndrome (with many deficits) how does that work if the nodules are negative? Can you have non-cancerous as well a cancerous nodules at the same time? Sure would like your opinion. I would apreciate it very much. Thankyou Lisa
