Left lung space-occupying lesion. What does that mean?

Left lung space-occupying lesions should first be considered as lung tumors. For left lung space-occupying lesions, enhanced CT is often required to evaluate the nature of lung masses. The next examination measures are determined according to the chest CT. If the central mass is often required, lung biopsy by fiberoptic bronchoscopy is often required. If the peripheral mass is often required, percutaneous lung biopsy is required for further definite diagnosis. It should be noted that in addition to lung tumors, space-occupying lesions in the left lung can also be seen in other diseases, such as tuberculosis, and inflammatory pseudotumors.
