What Is a Lung Nodule?
9. Biopsy
As mentioned, it is very important to find out whether or not any discovered lung nodules are indeed cancerous. This is achieved by way of a biopsy, and this means physically taking a sample of the lung tissue so it can be closely examined. Intrusive surgery is sometimes needed to perform this, depending on where about the nodule is.
While large nodules can be detected by x-ray, smaller ones can be missed. This means that a CT scan can also be required to be sure that none have been missed. Even an intrusive lung biopsy should be a relatively straight forward procedure.
