Commonly called a “spot on the lung” or a “shadow,” a nodule is a round area that is more dense than normal lung tissue. It shows up as a white spot on a CT scan. Lung nodules are usually caused by scar tissue, a healed infection that may never have made you sick, or some irritant in the air. Sometimes, a nodule can be an early lung cancer. The features of the nodule combined with the patient’s risk factor determine the chance of malignancy. At the TruDoc Medical we follow the most advanced algorithms in tracking the behavior of such nodules. We combine genetic testing and genomic modifiers to decide on the best next step for the management of the lung nodule. If you or your loved one was told they have a nodule, please call, and schedule an appointment.
