Does sunscreen protect against cancer?

Sunscreen can help prevent skin cancer by protecting the skin from harmful UV rays, but it is not a guarantee against cancer and it is important to also practice other sun safety measures.

Complete answer

Sunscreen can indeed protect against skin cancer to an extent, but it is important to understand that it is not a foolproof solution. The American Academy of Dermatology recommends using a broad-spectrum sunscreen with an SPF of 30 or higher, which blocks both UVA and UVB rays, and to reapply every two hours or after swimming or sweating.

According to a report from the World Health Organization, regular sunscreen use has been shown to reduce the risk of melanoma, the deadliest form of skin cancer, by up to 50%. However, it is important to note that sunscreen alone cannot fully protect against skin cancer.

Other sun safety measures must also be taken, such as seeking shade during peak sun hours, wearing protective clothing like hats and long sleeves, and avoiding tanning beds.

In the words of dermatologist Dr. Diane Berson, “Sunscreen is one arrow in our quiver. It’s not the whole answer.”

Here are some interesting facts about sunscreen and skin health:

  • Sunscreens come in two forms: chemical (which absorb UV rays) and physical (which deflect UV rays). Both types can be effective.
  • There is some concern that certain chemicals in sunscreens may be harmful to human health or the environment. The FDA is currently evaluating the safety of several sunscreen ingredients.
  • People with darker skin tones are less likely to develop skin cancer, but they can still benefit from using sunscreen to prevent premature aging and other sun damage.
  • It is possible to get a sunburn (and increase your risk of skin cancer) on cloudy or overcast days, as UV rays can penetrate through clouds.
  • Skin cancer rates continue to rise globally, with an estimated 7,000 people dying from melanoma each year in the United States alone. Taking steps to protect your skin from the sun is crucial for maintaining good health.

When used as directed, sunscreen is proven to: Decrease your risk of skin cancers and skin precancers. Regular daily use of SPF 15 sunscreen can reduce your risk of developing squamous cell carcinoma (SCC) by about 40 percent, and lower your melanoma risk by 50 percent.

Sunscreen reduces your overall UV exposure and lowers your risk of skin cancer and sun damage.

Several well-conducted randomized controlled trials with long follow-up showed that sunscreen use reduces the risk of squamous cell and melanoma skin cancers. Commercial sunscreens protect against the skin-damaging effects of ultraviolet radiation through either chemical or physical ingredients.

The most important benefit of sunscreens is that they protect you from UV rays that can cause skin cancer. Skin cancers are the most common cancers in the U.S. Around 9,500 people are diagnosed with some form of skin cancer every day in the U.S., and two people die of skin cancer every single hour in this country. Protection from skin damage

Broad spectrum SPF is a designation that means a sunscreen protects against both UVA and UVB rays. This is the only way to adequately protect against the UV light types that cause skin aging as well as skin cancer.

Consider sunscreen as one part of your skin cancer protection plan, especially if staying in the shade and wearing protective clothing aren’t available as your first options.

Despite the mixed evidence, the American Academy of Dermatology recommends sunscreen to prevent skin cancer.

It’s important to protect your skin whenever you are outside, because of the risk for skin cancer. About 90% of non-melanoma skin cancers and 65% of melanomas are associated with exposure to UV radiation from the sun. One of the best ways to protect your skin is to apply sunscreen.

The American Cancer Society recommends the use of sunscreen as one way to protect your skin from ultraviolet (UV) rays. UV rays from the sun – and from tanning beds and lamps – damage the skin and can cause skin cancer.

Using sun protection consistently from an early age is the strongest defense against developing skin cancer. No person or method is perfect, though, and one in five Americans will develop skin cancer by the age of 70.

The sun emits three types of ultraviolet rays, namely UVA, B and C. While UVC is filtered out by the Earth’s ozone layer, UVB and UVA rays can penetrate the skin and lead to skin cancer and DNA damage. Sunscreen absorbs UV photons and transforms them into harmless heat to protect the DNA, and sunscreen with zinc oxide and titanium dioxide is considered a safe alternative to oxybenzone. Sunscreens are recommended along with other precautions like avoiding peak sun exposure hours and wearing protective clothing and hats to prevent wrinkles and skin cancer although more safety studies are being called for by the FDA.

It is interesting: Of the chemicals in the sunscreens tested for, oxybenzone was found to be absorbed within 30 minutes and reached the highest levels in blood. Oxybenzone, also listed as benzophenone-3 on labels, is a chemical that absorbs light and protects the skin from the harmful effects of UV radiation.
Interesting: The American Academy of Dermatology found that just over 40 percent of Americans tend to only reapply sunscreen when they get wet, if at all. "Sunscreen should be reapplied every two hours, or immediately after heavy sweating or swimming," Zeichner said.
