Dr. Eric Vallieres, thoracic surgeon, introduces us to and provides a brief history for the special case in lung cancer of a “Pancoast Tumor”, along with how its optimal treatment has evolved over several decades.

I've been meaning to write on tumor markers detectable in the blood for the management of lung cancer. These are proteins that are produced by some tumors, and the idea is that the levels of the tumor markers in the blood can potentially be used to monitor the status of the disease.
