BAC was first identified and defined as a separate subtype of lung cancer by Dr.

Here's a video slide presentation that provides a basic introduction to bronchioloalveolar carcinoma (BAC), including the demographics, natural history, imaging appearance, and patterns of response that make it a unique subpopulation within lung cancer. The audio only version is below the video.
