Skin Cancer Risk in the Military

By Julie Bain • July 11, 2018


The tightly woven fabric of uniforms, plus gloves, helmets, sunglasses and sunscreen, help protect U.S. Army paratroopers on the ground.

The brave men and women who serve our country know they accept some risks, but they may not know that one of them is skin cancer. We asked Jonathan L. Bingham, MD, a Mohs surgeon in Great Falls, Montana, and a flight surgeon with the Montana Air National Guard, to tell us more about this danger.

Q: Having served for 24 years in the U.S. Navy, including 15 years on active duty, you’ve seen some diverse terrain, from desert to water to high altitude. You also spent many years as a dermatologist and chief of Mohs surgery at Walter Reed National Military Medical Center in Bethesda, Maryland. What have you learned about the risks of skin cancer in our military personnel?

Dr. Bingham: Historically, some studies have shown that the military has a higher rate of skin cancer overall than the general population, but some studies have suggested the opposite. A recent, well-done review article in the June 2018 Journal of the American Academy of Dermatology shows that, indeed, those who have served are at a greater risk of developing skin cancer than those who have not served.

People who served in World War II in the Pacific had a high rate of skin cancer, as well as people who served in the tropics, like Panama. I hope we’ve learned a lot since then. But let’s be clear: the rate of skin cancer in the general population is high. More people are diagnosed with skin cancer in the U.S. every year than all the other cancers combined. And there is certainly the potential for risk in the military, especially in certain types of terrain and situations.

Some studies have looked at skin cancer rates in the military by service. The Air Force has the highest rate, in both melanoma and nonmelanoma skin cancer. If you break it down by rank, officers, especially older officers, tend to have a greater rate of melanoma and nonmelanoma skin cancers than the enlisted personnel. Finally, when you break it down by job description, there is a greater incidence of it in pilots compared with service warfare officers who spend time on board ships. The lowest incidence of skin cancer in the military is in people who are in mechanized units, the people who work with tanks and probably spend a lot of time inside the tanks. I don’t know if they looked at the submariners, but I would think the incidence would be pretty low there, too!

Brutal sun: A wide-brimmed boonie hat helped protect Dr. Bingham from the desert sun while stationed in Kuwait in 2003.

Q: I would think sun protection would be crucial in a hot desert climate. You spent time in the Middle East. What did you observe there?

Dr. Bingham: I was a flight surgeon with the 2nd Marine Aircraft Wing, and I served in Operation Iraqi Freedom in 2003. Yes, there was plenty of opportunity for sun exposure there, just given the climate. When it was operationally feasible, the military tried to outfit us in a way that would help protect us from the sun. I remember we would wear these military boonie style hats with a wide brim. Those were helpful. Our uniforms had long sleeves in tightly woven fabric, which helps to protect skin from the sun. But only if you could stand them, because gosh, there were days when the temperature was over 120 degrees.

Q: Was sunscreen available to you, and did anyone talk about it?

Dr. Bingham: Sunscreen was talked about. One of the reasons was because doxycycline, a medication that we used for malaria prevention, makes you photosensitive, meaning you’re more apt to get a sunburn. It was not uncommon that we saw people with sunburns, and part of that was because they were on this medicine.

Sunscreen was not routinely or commonly issued at that time, but it was available in the PX, a little general store on the base. In my case, family members sent me care packages from home that usually included sunscreens. Still, we had people who didn’t practice good sun protection. I remember one of the worst sunburns I’ve ever seen in my entire medical career was a Marine in my unit who drove an ambulance. One day he just did not put on any sunscreen or wear a hat on his completely shaven head. As a result, he had one of the worst scalp sunburns I’ve ever seen.

Q: I assume wearing a lot of equipment and protective gear as part of a uniform helps serve as a barrier to shield troops from the sun’s ultraviolet (UV) rays. But isn’t there also down time and the temptation to bask in the sun a little, like we’ve seen in movies?

Dr. Bingham: During World War II, and in Vietnam, it was pretty commonplace to take off your shirt and get a tan — if the commanding officer allowed it. I think you don’t see that aspect of the military as much now. I don’t remember ever seeing someone walking around our base in the Middle East without a shirt on. That might have been acceptable many years ago but certainly not in today’s military.

Q: Did you spend much time shipboard? It seems like being out on the water with lots of sun, reflection and little shade would be a recipe for sunburn.

Dr. Bingham: During all my years in the Navy, I think I spent a grand total of eight weeks at sea! When I wasn’t assigned to Bethesda and did operational medicine, I was usually stationed with the Marines, land-based somewhere. But I did spend a short period of time on a guided missile cruiser based out of Washington. And I did my undergrad work at the Naval Academy in Annapolis, where we learned how to sail. The amount of sun exposure you can get out on the water is incredible, especially if you’re outside on watch on the deck of the ship. But it is my understanding, in talking to a colleague who spent a lot of time on ships, that they’re very mindful of that now. Sunscreen is encouraged and readily available, as is wearing protective clothing and sunglasses on board the ships. This holds true for anyone just out having fun on a boat, too, of course!

Q: We know that pilots, whether private, commercial or in the military, are exposed to dangerous UV radiation at high altitude in flight. As a flight surgeon, what did you experience while spending a lot of time in the air?

Dr. Bingham: While there are a lot of flight surgeons who are what we call “dual designated,” meaning they are also pilots, I was purely a flight surgeon. And while I did have the opportunity to fly, my primary job was patient care. I did get a lot of flight time in the HH-46 helicopter as well as the C-9 Greyhound. Now I get to fly in the C-130 as a member of the Montana Air National Guard.

Today a lot of the more modern military aircraft cockpits are designed to protect pilots from more of the UV radiation exposure. But we are still flying older aircraft like the C-130s and certain types of helicopters, and those pilots need to use sun protection. They can’t wear a boonie style hat because of the headphones they have to wear. So in the unit I’m with now, I recommend that all of my pilots wear baseball caps, sunglasses and sunscreen as well. In fact, I give an annual skin cancer briefing every year to all the pilots. Pilots who aren’t in the military should also protect themselves while in the air.

Danger in the cockpit: Military pilots need to protect themselves from UV radiation while flying, especially in older aircraft like the C-130.

Q: Speaking of altitude, you’re currently practicing in Montana. What do people need to know about the risks of skin cancer while in the mountains?

Dr. Bingham: Mountain altitude is certainly an issue. There’s a group called the 10th Mountain Division. They were the skiing soldiers of World War II, and the unit is still trained to fight in mountainous and arctic conditions. These individuals also have a fairly high rate of skin cancer. I have seen many of the 10th Mountain Soldiers as patients over the years. They are incredible veterans to speak with and get to know.

Levels of ultraviolet radiation increase by up to 24 percent for each 1,000-meter increase in altitude. Skiers and hikers need to understand this risk, too. I did my Mohs surgery fellowship at the University of Colorado Medical Center, and I was assigned to the ROTC unit at Boulder. The amount of skin cancer I saw that year was incredible. Montana is the same way. People just love being outdoors, and they need to protect themselves all year long.

Q: How would you answer a parent with a family history of skin cancer asking, “I’m worried about my kids getting too much sun exposure in the military. Is there anything I can do?”

Dr. Bingham: I would say, “I strongly suggest you frequently send them a care package with a lot of sunscreen in it.” The typical age of someone who is serving in the military is younger than 25. At that age, they feel like they’re invincible, that there are more important things to buy than sunscreen and more important things to do than use sunscreen. If they are going to serve in an area that’s closer to the equator, on water, in the air or at a high altitude, they certainly have to be concerned about that and wear as much protective clothing as possible. I am grateful that the military recognizes and is aware of the risks and is taking a lot more measures today to encourage Soldiers, Sailors, Airmen and Marines to protect themselves from the sun.
