@bellsina71, I can certainly understand how scared you must be. A lung nodule (or mass) is a small abnormal area that is sometimes found during a CT scan of the chest. It's natural that your first thought leaps right to cancer. There are many different types of growths that can form in the lungs that are easy to treat or don't even require treatment. @deedee1981's story is a good example of a mass not being cancerous.

IF your mass is cancer, then you are doing everything right. You are in medical care and a PET scan has been scheduled.

The hardest job you have now is to de-stress while you wait. Not easy I know. But remember that no matter the outcome, being of healthy mind and body is your best bet. What things help you feel calm or distract you?
