    Transcript

    00:02 Alright, ladies and gentleman, let's take a look at lung cancer. Lung nodule versus a cancer. What’s going on here? A solitary pulmonary nodule. Remember, just because you find a nodule within, let's say CT, you have to be careful, don’t you? Because that density that you’re gonna find, it could be number of things. If its a small density that you’re going to find and there’s many of them, you’re a little worried now because maybe that’s metastasis. If you find a large nodule and it’s rather wide and calcific, then you might be thinking along the lines of granulomatosis with polyangiitis or granulomas, in general. But, if it’s solitary pulmonary nodule, a single density, found on imaging studies such as a CT, in which it’s less than 3 cms in diameter. Now, as a general rule, that 3 cm, you can apply many places including the nodule that you find in the liver, that you might found with cirrhosis, micro-macro nodule. They’re surrounded by normal lung parenchyma, solitary pulmonary nodule, this is not the cancer.
