4 Shocking Things You Probably Don't Know About Skin Cancer

It's warming up out there, and as always, the annual media drumbeat about the importance of sunscreen gets louder as the sun climbs higher in the sky.

But slathering on the SPF isn't just about keeping sunburn at bay—the threat of skin cancer is actually higher than you probably thought. How much to you really know about your skin's health, and what you can do to protect it? Read on to find out.

1. Scientists just discovered a groundbreaking new treatment.

Let's start with the good news: On Monday, researchers found an even more effective way to treat skin cancer.

Two clinical trials published in the New England Journal of Medicine found that combining two cancer drugs to treat advanced cases of melanoma was incredibly effective. For a few patients, these two drugs worked even better than the current leading treatment for melanoma.

Doctors and skin cancer patients are especially thrilled with this discovery because melanoma is so deadly. As many as 80 percent of patients die from the disease, according to the Cleveland Clinic.

2. Skin cancer is the most common cancer.

Nearly 5 million people are treated for skin cancer every year, according to the Skin Cancer Foundation. That's more new cases of skin caner each year than breast cancer, prostate cancer, lung cancer, and colon cancer combined.

Older adults are most likely to be diagnosed with skin cancer, but all age groups are really at risk.

3. Going to the tanning salon isn't any safer than tanning outdoors.

Listen up, tan-a-holics: More people get skin cancer from indoor tanning than get lung cancer from smoking.

Health officials consider indoor tanning so dangerous that a few countries have actually outlawed it. Good luck finding a tanning salon in Brazil or most of Australia.

4. Sunburns are more dangerous than you might think.

Your risk of melanoma—the deadliest variety of skin cancer—doubles if you've been sunburned more than five times.

In fact, 90 percent of all skin cancers (excluding melanoma) can be linked to exposure to UV rays.

And if you need even more convincing that the sun is not your friend, how about this: Sunlight is also responsible for fine lines, wrinkles and age spots. As much as 90 percent of the changes you see in the mirror can be linked back to the sun.

But you can fight back. Using a sunscreen with at least 15 SPF daily lowers your risk of developing skin cancer by 40 to 50 percent, depending on the cancer. Plus, sunscreens and moisturizers also keep your skin looking young and healthy—you can't beat that.

A Basic Guide to Cow-Free Milk

  • Dean

    With the beginning of the sunny season, a frequent question that comes up is what sunscreen we recommend. When I answer ‘a good tan’, I get many surprised looks. While I’m not suggesting that we all slather on the suntan oil and sit with reflectors, the paranoia about getting sun exposure and tans is not well backed in the research literature.

    The first thing to recognize is that there are 3 main types of skin cancers; basal cell carcinoma, squamous cell carcinoma, and malignant melanoma. Basal and squamous cell carcinomas, known as the nonmelanoma skin cancers, account for well over 90% of all skin cancers, and are easily treated with over a 95% cure rate. Malignant melanoma is far less frequent, but responsible for 75% of all deaths from skin cancer. Almost all resources that you look at will tell you that avoiding the sun and using sunscreen is the way to prevent skin cancer, and they are correct; If you’re referring to the nonmelanoma skin cancers.

    The problem is that the relationship between sun exposure and melanoma is unclear at best. In fact, a recent meta analysis, a large study where they look at all the previous good studies in the area, concluded that, “No association was seen between melanoma and sunscreen use”, meaning that the use of sunscreen is not protective against melanoma. Even more surprising is a finding from the Journal of the National Cancer Institute that, “Sun exposure is associated with increased survival from melanoma.” You might need to read that again, but it’s exactly the opposite of what most people believe - if you do get melanoma, having gotten plenty of sun exposure actually increases your chance of surviving it.

    Add to that the knowledge that many sunscreen ingredients are hormone disruptors, are themselves capable of causing damage to skin cells, one of the initiating events in skin cancer. So, sunscreen itself can cause skin cancer, doesn’t protect against melanoma, and actual exposure to the sun can save you if you do have melanoma; sounds like a whole lot of confusion. Also, there are studies showing that good sun exposure lowers rates of Multiple Sclerosis, and several cancers, even cutting the rate of advanced breast cancer in half! Remember that the only natural way to get your vitamin D is to be exposed to the sun. In Northern latitudes it’s unlikely that even long days in the sun is enough to get you sufficient levels of vitamin D, which is why you need to test levels and supplement, but it’s a good start.

    There are several studies that point to intermittent, intense sun exposure being the real culprit for sun damage, so I generally recommend that people go out in the early spring when the sun is still weak, and begin to build a good base tan to protect them. Once May comes, my family is outside in shorts and tank tops as often as possible. Start early, start slow and be ready for the summer when the rays are much stronger. If you do want to use sunscreen, there are two FDA approved sunscreens that are widely available that don’t have the chemical toxicity issues – Zinc Oxide and Titanium Dioxide. These are both mineral-based sunscreens that physically block the UV rays from contacting the skin, as opposed to trying to chemically alter the rays. In my days as a lifeguard, the Zinc Oxide was a thick white paste we used to wear on our noses.

    Today the technology allows them to micronize it, so that it doesn’t look like you have anything on. There is some concern with the micronization process that it may allow the molecules to penetrate deeper into the body. My preference is therefore the Zinc Oxide because it’s a necessary trace element, so any that may be absorbed through the skin shouldn’t cause any problems. These physical sunscreens will protect the skin better than the chemical sunscreens, without the dangers. They will however, decrease your sun exposure and the benefits of the vitamin D synthesis.

    Finally, there are studies showing a protective effect against skin cancer from multiple foods and nutrients, including the omega-3 fatty acids and green tea. So take your Cod Liver oil or EPAs, take a lounge chair outside, sit down to a nice cup of green tea, and enjoy the warmth and healing of the sun.
