The American Cancer Society Cancer Action Network (ACS CAN) is the nation's leading cancer advocacy organization. ACS CAN works with federal, state, and local government bodies to support evidence-based policy and legislative solutions designed to eliminate cancer as a major health problem. Skin cancer is the most prevalent type of cancer in the United States, and melanoma is the third most common form of cancer for individuals aged 25-29 years. Ultraviolet (UV) radiation exposure from the sun is a known cause of skin cancer and excessive UV exposure, particularly during childhood and adolescence, is an important predictor of future health consequences. The link between UV exposure from indoor tanning devices and melanoma is consistent with what we already know about the association between UV exposure from the sun and skin cancer. This is why the International Agency for Research on Cancer (IARC) in 2009 elevated tanning devices to its highest cancer risk category – “carcinogenic to humans.”1 While sun exposure and tanning beds both produce potentially harmful UV radiation, powerful tanning devices may emit UV radiation 10 to 15 times higher than that of the 1 Ghissassi, et al.

  • Indoor Tanning
    INDOOR TANNING What is INDOOR TANNING? Using a tanning bed, booth, or sunlamp to get tan is called "indoor tanning." Indoor tanning is linked to skin cancers including melanoma (the deadliest type of skin cancer), squamous cell carcinoma, and cancers of the eye (ocular melanoma). What are the dangers of indoor tanning? Indoor tanning exposes users to both UV-A and UV-B rays, which damage the skin and can lead to cancer. Using a tanning bed is particularly dangerous for younger users; people who begin tanning younger than age 35 have a 75% higher risk of melanoma. Using tanning beds also increases the risk of wrinkles and eye damage, and changes skin texture. Is tanning indoors safer than tanning in the sun? Indoor tanning and tanning outside are both dangerous. Although tanning beds operate on a timer, the exposure to ultraviolet (UV) rays can vary based on the age and type of light bulbs. You can still get a burn from tanning indoors. A tan indicates damage to your skin. Can using a tanning bed to get a base tan, protect me from getting a sunburn? A tan is a response to injury: skin cells respond to damage from UV rays by producing more pigment. Prevent skin cancer by following these CDC tips: • Seek shade, especially during midday hours. • Wear clothing to protect exposed skin. • Wear a hat with a wide brim to shade the face, head, ears, and neck. • Wear sunglasses that wrap around and block as close to 100% of both UVA and UVB rays as possible.

  • Replacement of Tanning Lamps with Red Light Therapy Lamps in Tanning Salons

Subject Replacement of Tanning Lamps with Red Light Therapy Lamps in Tanning Salons To Conference of Radiation Control Program Directors (CRCPD) The Food and Drug Administration is aware that some tanning salon owners are removing the original ultraviolet (UV)-emitting tanning lamps from their tanning beds/booths and replacing them with lamps that emit red light. These salon owners are then selling sessions in the red light units with a range of indications and promotional claims, including ones pertaining to: • Reversal of sun or UV damage to skin, • wound healing, • increased blood flOW/Circulation, • reduced pain and/or inflammation, • treatment of acne, • reduction of appearance of wrinkles, pigmentation spots, stretch marks, and/or scarring, • skin rejuvenation, restoration, oxygenation, and/or hydration, • collagen/elastin production/reorganization, and • skin structure, elasticity, and/or metabolism. Ultraviolet tanning beds/booths/lamps meet FDA's definition of "device" and "electronic product" at sections 201(h) and 531 of the Federal Food, Drug, and Cosmetic Act (FD&C Act). Tanning lamps are subject to an electronic product performance standard, and are generally 510{k)-exempt. See 21 CFR 878.4635, part 1010, and 1040.20, Replacing the original ultraviolet lamps with lamps that emit red light and are intended for uses such as those listed above creates a new type of product that is also a "device" and an "electronic product" under the FD&C Act. Exposure to red light has been scientifically shown and is understood by consumers to affect skin structure, for example by reducing wrinkles for months after treatment, which may be the result of new collagen formation or reorganization, or repair of elastin damage.

  • ACTINIC KERATOSIS Signs and Symptoms: Diagnosis: Types of Treatment: Treatment Outcome
    ACTINIC KERATOSIS Actinic keratosis (AKs) are rough, scaly patches or growths that form on skin that has been damaged by ultraviolet (UV) rays from the sun or indoor tanning. AKs are thought to be precancerous, and can progress to become a squamous cell carcinoma. The prevalence of this condition increases with age. According to the Skin Cancer Foundation, actinic keratosis is the most common precancerous lesion, affecting more than 58 million Americans (http://www.skincancer.org/skin-cancer-information/Actinic-Keratosis). Signs and Symptoms: • Most people with AKs will only notice changes to their skin. Symptoms include a rough-feeling patch on the skin that cannot be seen; a similar crusty patch or growth that feels painful when rubbed; and/or an itchy or burning area of skin. • An AK can appear on the skin, remain for months, and then flake off and disappear from the skin’s surface. While the skin may suddenly feel smooth, many AKs re-appear in a few days to a few weeks. Even if an AK does not re-appear, you need to be under a dermatologist’s care. Diagnosis: • An AK is diagnosed following close examination of the skin. If a growth is found that is thick or looks like skin cancer during the examination, a skin biopsy will be performed as an in-office procedure. Types of Treatment: • The decision to treat is based on symptom relief or, most importantly, the prevention of malignancy. Treatment options include ablative (destructive) therapies such as cryosurgery, curettage with electrosurgery, and photodynamic therapy. For patients with multiple lesions, topical therapies can be used, including Fluorouracil, Imiquimod 5% cream and Diclofenac 3% gel.

  • The Darker Side of Tanning
    The Darker Side of Tanning Public health experts and medical professionals are continuing to warn people about the dangers of ultraviolet (UV) radiation from the sun, tanning beds, and sun lamps. Two types of ultraviolet radiation are Ultraviolet A (UVA) and Ultraviolet B (UVB). UVB has long been associated with sunburn while UVA has been recognized as a deeper penetrating radiation. Although it's been known for some time that too much UV radiation can be harmful, new information may now make these warnings even more important. Some scientists have suggested recently that there may be an association between UVA radiation and malignant melanoma, the most serious type of skin cancer. What are the dangers of tanning? UV radiation from the sun, tanning beds, or from sun lamps may cause skin cancer. While skin cancer has been associated with sunburn, moderate tanning may also produce the same effect. UV radiation can also have a damaging effect on the immune system and cause premature aging of the skin, giving it a wrinkled, leathery appearance. But isn't getting some sun good for your health? People sometimes associate a suntan with good health and vitality. In fact, just a small amount of sunlight is needed for the body to manufacture vitamin D. It doesn't take much sunlight to make all the vitamin D you can use certainly far less than it takes to get a suntan! Are people actually being harmed by sunlight? Yes. The number of skin cancer cases has been rising over the years, and experts say that this is due to increasing exposure to UV radiation from the sun, tanning beds, and sun lamps.

  • Tanning Salons Fact Sheet
    Fact Sheet Adopted: January 2010 Health Physics Society Specialists in Radiation Safety Tanning Salons General Tanning is the skin’s response to ultraviolet* (UV) radiation, a type of light exposure. As skin cells are exposed to UV radiation, they produce brown pigment to protect themselves from further UV exposure. This results in a darkening of the skin (tanning), which is the body’s natural defense mechanism and attempt to prevent further damage from UV radiation. Sunlight and artificial tanning methods, such as tanning booths or salons, are sources of UV exposure. Sufficient amounts of UV exposure are known to cause adverse health effects in humans and are a public health concern.
