The Sun is Out: What You Need to Know about Skin Cancer

So many of my patients think that they don’t need to worry about protecting themselves from the sun. But the sun doesn’t always respect your age, lifestyle, or skin color. Today, we look at some myths around skin cancer.

1. I have dark skin, so I don’t need protection. Unfortunately, darker skin does not guarantee you won’t get skin cancer. Yes, I (an African-American) may be less likely to get it than my white friends, but African American and Hispanics who develop the aggressive skin cancer melanoma are more likely to die from the disease than whites. Part of the difference may be delays to evaluation: So if in doubt, check it out!

2. Tans are healthy and reduce skin damage. While a base tan can delay sunburn, the ultraviolet light is still damaging away. The DNA in suntanned skin has already been damaged by ultraviolet radiation. It is DNA damage that can lead to cancer. So, if you are trying to leave your skin healthier, avoid the tanning bed, the sun lamp, and tanning in general.

3. I can’t develop skin cancer in the parts of my body that are not exposed to the sun. While sun-exposed areas are the most risky, cancer can develop in virtually any skin area.

4. Since I use sunscreen and try to spend too much time in the sun, I won’t get skin cancer. While it is true that these maneuvers lower risk, they do not drive it to zero. And many individuals don’t use sunscreen properly. Aim for an SPF 30 or higher, applied 30 minutes before sun exposure. This allows for absorption into the skin. Then remember to reapply appropriately, including after you leave the water. Try to avoid high sun times, such as between 10am and 4pm. For extra credit, remember the hat and long sleeves!

  1. Very helpful information, thank you. Living on the shore means much sun exposure. Is there a recommended frequency for reapplying sunscreen?
