A nodule in the lung that grows to 8 cm is very large, and is generally not called a nodule, but a mass or an occupying lesion. There are several diseases to identify. If the inflammatory disease is this large, it could be a bulbous inflammatory lesion, which is usually prone to form a pre-pulmonary abscess, or a tuberculosis bulb or mycobacterial bulb, which would be present. More often, it needs to be identified as a benign or malignant tumor because the location is very large and the effect on lung function can be very serious. Because of such a large occupying lesion, it can obstruct the airways. Moreover, such a large lesion is usually not a stable lesion in the lung, and if it is inflammatory in the short term, it may start to fester and discharge a lot of fishy pus and sputum. If the lesion is malignant, it may have already started to destroy the lung tissue, instead, we should pay attention to it and seek medical attention in a timely manner, so we can’t spend any more time on our own.
