In our study, the investigators are planning to do biopsies with or without suction. Then, the pathology samples will be evaluated for any cytologic difference in making the diagnosis. Any patient undergoing the EBUS procedure for chest biopsies will be eligible. Every lesion will be biopsied at least twice with needle with and without suction. The biopsy samples will be then divided into group A where the investigators applied syringe suction and group B where no syringe suction was applied. There is no risk to the patient in addition to the risk of the EBUS procedure itself. The investigators are not performing any additional intervention from the usual standard of care for any patient presenting for the EBUS procedure. Essentially the investigators are simply grouping the suction and no suction pathology samples as A and B for pathologic comparison.
