Protecting Yourself From Skin Cancer

By Dr. Kerry Shaughnessy

Hello!  May is national Skin Cancer Awareness month, which makes good sense given that we’re heading into summertime and peak sun-tanning season. What better time for some helpful sun protection tips from your friendly Water’s Edge dermatologist?

Note that this will be my first summer spent in Florida, so it’s important information for me to review as well!

Protecting your skin from the sun helps prevent skin cancer, plain and simple.  It doesn’t matter how dark your skin is or how easily it tans—you still need to protect it.

Sunscreen is a great start, but it’s only part of the equation.  First, make sure your sunscreen is at least SPF 30 and “Broad Spectrum.”  That means it protects against both UVA and UVB rays.

I’ve been asked many times, “Does sunscreen go bad?” Well, the answer is that experts agree three years is about it before it’s time to toss out the old, and purchase the new. But what I really love about this question is, if you’re asking, it probably means you aren’t using enough sunscreen!

On average, it should take about 1 shot glass or 2 ounces of sunscreen to cover your entire body. And don’t forget to reapply at least every 80 minutes - 2 hours, and more often if you’re sweating or swimming. If you’re using sunscreen the way it’s meant to be used, you go through it the way I go through Diet Coke.

Another question I get a lot is, “Which sunscreen is best?” Answer: The one you’re going to use.  Seriously.  If it’s not affordable or you don’t like the smell or consistency, you’re not going to use it.  Stick, spray, lotion, oil—whichever you like best.  Just make sure it’s at least SPF 30 and broad spectrum, and you’re good to go.

But remember, sunscreen is only part of an effective protection plan.  Slip on a hat—broad brimmed is optimal because it protects your ears and the sides of your neck and face.  But even I admit there are some activities where a baseball cap is more practical.  (Like cruising out the inlet to your favorite fishing spot!)

Don’t forget about your clothing and sunglasses-- long sleeves and long pants will help protect your skin and with performance fabrics today, they often keep you cooler and more comfortable too.  Polarized sunglasses are a must, especially in settings with a lot of reflected light (water, sand, etc.), and larger or wraparound frames offer greater protection.

If you do a lot of driving, consider having UV filters installed to the side windows of your vehicle.  It’s inexpensive, and it will be there protecting you every day.  We get an incredible amount of cumulative UV exposure through the driver’s side window.  There’s a reason skin cancers predominate on the left side of our body.  If you don’t believe me, look at your forearms and count the number of freckles on your left forearm versus your right.

See?  Told you so.

And why only the side windows? Because the windshield already filters UV radiation fairly effectively because of the composition of shatterproof glass.

When you’re out and about on foot, remember what your mother taught you.  Sit in the shade whenever possible, and avoid being out in the direct sun between 10 am and 3 pm when those UV rays are the strongest.

Last, but so important, is the need to carefully check every inch of your skin every month or so, looking for anything new, changing or bleeding in the way of moles or lesions of any kind.

Should you see anything questionable, it’s time to see your dermatologist and get it checked, “asap”. Most skin cancers can be cured if caught early enough, so early detection is key. And rest assured, should your self-exam turn up anything worrisome, the Water’s Edge office near you will find a way to squeeze you into even a heavily booked schedule.

Hope that’s all helpful. Looking forward to seeing you out, about and sun-protected this summer!

The Big Picture on Skin Cancer

The month of May is known for celebrations such as Mother’s Day and May Day. But it’s also Skin Cancer Awareness month, and based upon the staggering statistics, it’s no wonder why. Here are just a few of the worrisome facts, from the Skin Cancer Foundation:

  • During the past thirty years, more people have suffered from skin cancer than all other kinds of cancer, combined.
  • One out of five Americans will end up getting skin cancer in their lifetime.
  • Nearly 10,000 Americans die from melanoma each year.
  • More than $8 billion is spent every year in America on skin cancer treatment.
  • Approximately nine out of ten non-melanoma skin cancers are due to UV sun radiation.

Although many of us enjoy soaking up some sunshine and natural Vitamin D at the beach or other outdoor places, doing so without adequate protection isn’t healthy and greatly increases your chances of developing skin cancer later in life.  And in fact, quality vitamin supplements are a far safer way to get your Vitamin D than sunbathing or using tanning beds and lamps.

Speaking of safety, or lack thereof, note that according to the experts, anyone who subjects their skin to even one indoor tanning session before age 35 is increasing their risk of developing melanoma by 75 percent.

All that said, know that skin cancer is a highly preventable type of cancer. With adequate education, knowledge, behavior modification, and early detection through annual screenings at an experienced medical provider’s office, countless lives can be saved. Here are just some of the helpful prevention tips issued by the Skin Cancer Foundation, important reminders of the steps you and your loved ones can take to help protect yourselves from skin cancer:

  1. Shake the bake. Getting a sunburn five or more times in your lifetime doubles a person’s risk of getting skin cancer.  Avoid baking in the sun during its strongest hours, from 10 a.m. – 4 p.m. You can use your own shadow as a guide. If your shadow appears shorter than you, it means that the sun’s harmful radiation is still too strong. Time to seek shade or other protection.
  2. Dress for protection and help block UV rays by wearing hats, large wraparound sunglasses and loose-fitting clothes long enough to cover your arms and legs. And though you may have heard dark colors attract more heat, the fact of the matter is they offer far better sun protection, because those UV rays can’t penetrate them and get to your skin as easily.
  3. Wear and reapply  Choose a broad-spectrum sunscreen that has an SPF of 30 or higher (or a light moisturizer with SPF 30+ in it), and apply every morning. If you’re going to be outside for an extended period, apply 30+ sunscreen a short while before getting out under the sun, reapply every 75 or 80 minutes without fail or after any time in water, or after perspiring heavily.
  4. Do monthly self-examinations. Although not a substitute for a doctor’s exam, checking your skin each month and knowing what to look for in the way of new or changing moles or other skin lesions can help detect early warning signs of cancer. Early detection is a key component to beating cancer.
  5. Get an annual skin cancer screening from an experienced dermatological provider. Every year, without fail.
