Skin Cancer Myths and Facts

Myth: Skin Cancer is not a deadly disease.
Fact: More than 12,000 people are expected to lose their lives from melanoma and other nonepithelial skin cancers this year in the United States. Most deaths are due to melanoma, the most dangerous form of skin cancer.
Myth: Skin cancer only affects Caucasian men and women and those with lighter skin.
Fact: Everyone is at risk for skin cancer, though cases are most prevalent in those with lighter skin. People with fair skin are at a higher risk of developing skin cancer, especially fair-skinned individuals with freckles and/or blue eyes and red hair. However, because everyone is at risk of developing skin cancer, everyone should take precautions. In fact, though melanoma is less frequently diagnosed among African Americans, Latinos, and Asians than Caucasians, it is more frequently found in late stages and is often fatal for these populations. Everyone should seek annual skin cancer screenings with a dermatologist.
Myth: Tanning salons are a safe alternative to sun tanning without the risk of skin cancer.
Fact: A tanning bed produces UVA and UVB rays just like the sun. UVA (long-wave) rays damage the cell’s DNA and age cells, causing long-term damage such as wrinkles. UVB (shortwave) rays are stronger and cause sunburns and direct damage to the cell’s DNA. At times, the ultraviolet rays in a tanning bed may even be stronger than those emitted by the sun. UV radiation can cause skin damage, and in recent studies, has been linked to melanoma.
Myth: Skin cancer is diagnosed only in people who have considerable exposure to the sun’s rays.
Fact: Skin cancer can affect anyone, regardless of sun exposure, though it is more prevalent among those who have significant contact with the sun’s rays. Other risk factors include a family history of skin cancer and medical conditions and medications that suppress the immune system or increase your skin’s sensitivity to the sun. It is important to apply sunscreen every day you may be outside, even on hazy days or days with light or broken cloud cover, because UV light still permeates.
Myth: If the sun is not out or it is cold, there is no risk from the sun’s damaging rays.
Fact: The sun constantly produces ultraviolet rays, which can penetrate clouds and affect your skin even on overcast days or during cold weather. Snow, water, and sand reflect the sun’s rays making it important to wear sunscreen when you are around these. Remember that UV light is strongest between 10 a.m. and 4 p.m.
Myth: You only need to apply sunscreen once a day for proper protection.
Fact: Sunscreen works for a limited time. You should reapply sunscreen every two hours or according to the directions on the product label. Sunscreen should always be reapplied after swimming or participating in any activity that causes perspiration. Water-resistant sunscreens need to be reapplied every 40 or 80 minutes, according to the product label.
Myth: All sunscreens and tanning oils provide proper protection from the sun.
Fact: Experts recommend the use of a broad-spectrum (protects against both UVA and UVB rays), water-resistant sunscreen with a sun protection factor (SPF) of at least 30. Reapply every two hours or according to the product label. Water-resistant sunscreens need to be reapplied every 40 or 80 minutes, according to the product label. Recent FDA rules on product labeling prohibit sunscreen being labeled as “waterproof,” “sweat proof,” or “sunblock.” Wearing hats, sunglasses, and other clothing to cover body areas exposed to the sun is encouraged.
