What Is the Difference Between Small Cell and Non-Small Cell Lung Cancer? from Patient Empowerment Network on Vimeo.
Dr. David Carbone discusses the differences between small cell and non-small cell lung cancer. Dr. Carbone then describes the subtypes of non-small cell lung cancer and which types are most common.
Dr. David Carbone is a medical oncologist and professor of internal medicine at The Ohio State University. Dr. Carbone is also co-leader of the Translational Therapeutics Program at the OSUCCC – James, where serves as director of the Thoracic Oncology Center. Learn more about Dr. Carbone, here.

What is the difference between non-small cell lung cancer and small cell lung cancer?
Dr. Carbone:
Well, I like to tell patients every cancer is different from every other cancer, but they can be broadly categorized in two different categories, small cell and non-small cell.
And this derived from decades ago when small cell lung cancer just looked different under the microscope than non-small cell lung cancer. And different small cells can look different, and now we’re sub-typing small cells. But in general, small cells are treated pretty similarly. Non-small cells are divided into two main groups, the squamous cell carcinomas and the adenocarcinomas.
Adenocarcinomas have a variety of subtypes, as well, and then there are a few of the non-small cell lung cancers that are clearly non-small cell but don’t fit into either of those two categories, and they’re called large-cell or not otherwise specified.
And then, there’s a whole slew of rare types of lung cancers that we probably don’t have time to discuss, and mesothelioma that happened in the chest.
Katherine:
Right. Is one type of lung cancer more common than the other?
Dr. Carbone:
So, the vast majority of lung cancers are the non-small cell lung cancers, about 85 percent. And among the non-small cell lung cancers, most of those are adenocarcinomas or non-squamous. Decades ago, squamous was the most common type, and in some parts of the world, it still is. But in the United States, it depends on the region; 60, 70 percent of lung cancers are adenocarcinomas
