Ct scan showed very small lung nodule. I've had 3 chest x-rays prior and nothing showed on them. What happens now? How to determine if it's cancer?

Good luck and if you are a smoker, quit today. ...Read more

Are small lung nodules cancer?

Needs biospy: Small nodules can be cancer, but they would need to be biopsied. Many times, the nodules are just scars and not cancer. If you find nodules on a cat scan of your chest, depending on the size, they need to be followed to make sure they don't grow or look ominous enough to warrant a biopsy. What to do about nodules also depends on your risk for lung cancer, i.e., were/are you a smoker, etc. ...Read more
