As we dive into the hot summer months, it’s important to understand how we can stay safe and enjoy the sun, as well as the consequences of unprotected sun exposure.
One in five Americans will develop skin cancer by age 70, making it the most common type of cancer in the United States. Skin cancer is the abnormal growth of cells, the outermost layer of the skin. It appears differently on everyone depending on skin tone, size and location on the body, and type of skin cancer. If not detected and treated early, skin cancer can be fatal.
Fortunately, there are actions you can take to reduce your risk of skin cancer. Below, we’ve outlined four important facts about skin cancer that de-bunk common myths. Additionally, you’ll find preventive tips to help you protect your skin.
Artificial light sources can cause skin cancer.
The sun releases powerful ultraviolet (UV) radiation that can cause damage to the skin, early aging, and an increased risk of skin cancer. In addition to sun exposure, artificial light sources, such as tanning beds and sun lamps, also emit UV radiation. People who use indoor tanning devices have an increased risk of developing the two most common types of skin cancer – squamous cell carcinoma by 58% and basal cell carcinoma by 24%.
Vitamin D is available in natural food sources and supplements.
Vitamin D is an important nutrient that helps to keep your bones, muscles, and heart healthy. While sun exposure can be a good (and convenient) source of vitamin D, you can also obtain it through specific dietary choices or supplements.
According to the National Institute of Health (NIH), the best natural sources of vitamin D include fatty fish, like salmon, trout, tuna, mackerel, or fish liver oils. Dietary supplements or multivitamins are another way to ensure you get enough vitamin D. Reach out to your primary care doctor or advanced practice provider* (APP) to learn more about supplement dosage and average daily recommendations.
Another misconception is that regular application of sunscreen leads to decreases in vitamin D. According to the Skin Cancer Foundation, “clinical studies have never found that everyday sunscreen use leads to vitamin D insufficiency.”
Sunscreen should be applied and reapplied often, regardless of the time of day.
While the sun’s strongest hours are from 10 a.m. to 4 p.m., it’s important to protect yourself any time of day. Staying in the shade or wearing wide-brimmed hats, sunglasses, and protective clothing can help avoid sun damage. Since sunscreen’s protection lasts an average of two hours, remember to reapply often.
All skin tones are at risk of sun damage.
While people of color experience lower rates of skin cancer than white people, when diagnosed, it is unfortunately typically at a later stage and worse prognosis. Because of that, it is important for everyone to take steps to protect their skin.
According to the Skin Cancer Foundation, “skin tone is not the only risk factor: genetics, gender, age, certain medications and medical conditions play a role in determining your individual risk for developing skin cancer, too.”
Talk with your primary care doctor to learn more.
Spending time outside is a great way to enjoy the warmer months, and it can be done safely. At your next appointment, talk to your primary care doctor or APP to discuss more ways you can protect your skin from UV rays.
