Ultraviolet (UV) Radiation and Skin Cancer

  • The Surgeon General calls skin cancer a major public health problem. While fair skin and family history of skin cancer contribute to risk, the most common types of skin cancer are strongly associated with exposure to ultraviolet (UV) radiation1.
  • Two of the world’s most trusted voices on the causes of cancer, the World Health Organization and the National Toxicology Program, agree that UV radiation is carcinogenic to skin. (Wikipedia defines “carcinogen” as “directly involved in causing cancer.”)
  • Tanning beds and UV radiation from the sun are ranked “Group-1 carcinogens” by the World Health Organization, based on broad science3. The National Toxicology Program also rates tanning bed exposure as “known to be a human carcinogen.” Other carcinogens in this highest risk category include radon, tobacco and asbestos.

  • Indoor tanning is linked to more skin cancers than cigarettes to lung cancers. A University of California San Francisco study5 attributed over 388,000 new cases of skin cancer in the United States to indoor tanning each year, compared to just over 203,500 cases of lung cancer attributed to cigarettes. Lung cancer and tobacco-related illnesses cause many times more deaths than skin cancer. However, because of 1) the tremendous rise in new skin cancer cases in the U.S.,  2) the link of indoor tanning to skin cancer, and 3) the popularity of indoor tanning despite risk, indoor tanning is associated with a far higher number of cancers. 

  • Tanning bed use is linked to higher rates of all three major forms of skin cancer. These include deadly melanoma6 and the less deadly but often disfiguring non-melanoma7 skin cancers (basal cell and squamous cell carcinoma).

  • The number of non-melanoma skin cancers in the U.S. is estimated to be higher than that of all other cancers combined8.

  • Young people who tan indoors have higher rates at younger ages of basal cell carcinoma, the most common skin cancer9.
  • Both burns and gradual accumulation of UV damage10 in skin cells are associated with skin cancers, according to the Skin Cancer Foundation. Burns, however, are worse.
  • UVB and UVA are carcinogenic to skin cells in different ways3. UVB directly damages skin cell DNA. UVA causes indirect damage.
  • There is no such thing as a “SAFE TAN.” Any color the skin develops is a direct result of DNA damage to the skin cells11. This DNA damage accumulates and increases the risk of skin cancer.
  • Spray tanning and self-tanning lotions have not been shown to be carcinogenic.

Malignant Melanomatanningfact-60percent-pledge

  • Tanning indoors before age 35 increases your risk of melanoma by nearly 60%. An international study12 found that indoor tanning before age 35 raised the risk of getting melanoma by 59%13. Not only that, the risk was 1.8% higher with EACH additional tanning session12 in a given year.
  • One person dies of melanoma every hour in the U.S. The American Cancer Society Facts and Figures14 predicts one person will die about every 54 minutes in the United States from malignant melanoma in 2014. 
  • New cases of melanoma continue to climb in the U.S., even while most other serious cancers are leveling off or declining.  According to the American Cancer Society15, the annual percent increase for melanoma between 1992 and 2009 exceeded that of breast, lung, and colorectal cancers. 
  • Malignant melanoma is the single most common cancer of young adults, and one of the most common cancers in teenagers. A recent National Cancer Institute report16 ranked melanoma the number one cancer of adults aged 25-29 years, and the second highest in adolescents and young adults aged 15-25 years.

  • Nebraska had the highest mortality from melanoma in the nation per capita in women in 2007-2008, and the second highest in men 17.

  • Melanomas are developing earlier and more often in young women than in young men18. Is it a coincidence that 70% of the one million people who tan in the U.S. each day are young women19?
  • A Minnesota study20 showed an astounding 24-fold melanoma increase in women aged 40-60, compared to only a 4.5-fold increase in men of the same age.
  • The most common location of melanomas on young women has changed from the legs to the trunk. This may be related to exposure trends, including exposure in tanning beds21.
  • Invasive melanoma in young people is linked to indoor tanning at earlier ages, and to repeated tanning. A 2010 multi-center study22 of young adults found that, in persons aged 18-29 years with invasive melanoma who had ever used a tanning bed, “76 percent of melanomas were attributable to sunbed use.” 
  • In addition, they reported that “the association was stronger for those who [started tanning] at an earlier age22.” Finally, they concluded that “those who reported more than 10 lifetime sessions appeared some six times more likely to be diagnosed with melanoma before 30 years of age compared with never-users22.”
  • The stronger the tanning bed, the higher the risk. Another Minnesota study23 showed that so-called “high speed” or “high intensity” machines (that boost UVB) led to nearly a 3-fold rise in melanoma. “High pressure” devices that intensify UVA caused over a 4-fold increase.

UV Radiation and Skin Aging

  • As if higher cancer risk wasn’t bad enough, there is more bad news.  Tanning makes your skin age faster30. Professional models know this and use self-tanners or spray tans.  And more and more they embrace their own natural skin tone.
  • You can’t see or feel UV. UV radiation from the sun and tanning beds is emitted in waves longer than X-rays and shorter than visible light. UV is invisible and you can’t feel it (until later!)  So your senses can’t tell you how large a dose of UV your skin is getting.
  • UVA (think A for Aging) penetrates deeply into both layers of skin and damages collagen and elastin. This is how UVA exposure leads to premature aging, including sags, bags, wrinkles and lines where you don’t want them.
  • UVB (think B for Burning) is higher energy but only penetrates into the top layer of skin. Besides burns, UVB causes blotches and pigment irregularities.
  • Sunscreen decreases aging changes31 caused by UV radiation exposure.

UV Radiation and Seasonal Affective Disorder

Indoor Tanning Devices

  • Still, tanning beds are minimally regulated.  A warning sign on the device is the only FDA requirement that is enforced.  The FDA publishes upper limits of exposure, but does not enforce them, so the limits are often ignored33.
  • Tanning units account for over 1,800 Emergency Room visits a year for BURNS37. This underestimates the true number of burns handled in doctor’s offices, urgent care facilities, or treated at home. Nearly 60% of patrons of tanning facilities report having been burned38.
  • Your skin remembers EACH tanning session. Just one indoor tanning session before age 35 increases risk of melanoma by 59%, and each additional use during the same year boosts risk6 by another 1.8%.
  • The beds in most facilities appear to be sanitary, but what you can’t see may amaze you. A medical team in New York City swabbed the center of 10 upscale “Best of New York” Manhattan tanning beds, where skin contact typically occurs.  All 10 beds harbored bacteria39 (including staphylococcus, enterococcus, klebsiella, enterobacter, pseudomonas, and bacillus).  All of these bacteria can cause skin infections.
  • Warts40, even genital warts41 have also been linked to tanning beds.
