Screening guidelines are heavily tested on all the USMLE exams (especially 2CK/3). In this extremely HY podcast, I discuss all you need to know from a screening perspective for NBME exams. I categorize things in a way that makes remembrance extremely easy. You will get many questions right from this podcast on your exam.
EDIT: For lung cancer, it’s a 20 pack year history (not 30 pack years). Apologies for the confusion.
