This study focuses on individuals who have a suspicious lung nodule that is or will be scheduled for a lung biopsy. The purpose of the study is to compare the performance of a test called LungLB to standard-of-care biopsies to find lung cancer. LungLB is an investigational test that detects circulating tumor cells in order to correlate the results of the LungLB test with biopsy results. It is not intended as a screening, confirmatory or stand-alone diagnostic test. The study will access medical records to collect information about participant demographics, socioeconomics, social history, disease status, and relevant clinical and pathology information.
