Pulmonology List of Most Commons for Physician Assistant Students

This topic deserves an introduction. Why? Because it is Lung Cancer Awareness Month. How many of you have ever heard of Lung Cancer Awareness Month? Exactly. That’s probably because Breast Cancer Awareness Month probably stole its light in October. Unfortunately, breast cancer does not cause the most mortality in the United States, lung cancer does; that goes for men and for women. Why is this? Probably because there is not a unified and inexpensive diagnostic screening method for lung cancer as there is for breast cancer. Lung cancer causes almost double the number of deaths per year as breast, colon/rectal, and prostate cancers. Nonsmokers living with smokers have more than a 30% increased risk for developing lung cancer, regardless of whether or not the smoker is physically smoking around the nonsmoker or not. A diet rich in fruits and vegetables may protect against the development of lung cancer in smokers. However, high dose supplements of beta-carotene (also found in carrots) has been shown to increase the risk for lung cancer and is not recommended. So there you go. I have increased your knowledge about lung cancer in a matter of a few minutes. Hopefully now you will remember that every november is Lung Cancer Awareness Month and that you will remember to include lung cancer in your differential and to screen folks for it when necessary.
