Skin Cancer Facts

Skin Cancer Facts – provided by The Skin Cancer Foundation

GENERAL

• Skin cancer is the most common form of cancer in the United States. More than 3.5 million cases in two million people are diagnosed annually.³⁷
• Each year there are more new cases of skin cancer than the combined incidence of cancers of the breast, prostate, lung and colon.³
• One in five Americans will develop skin cancer in the course of a lifetime.²⁶
• Basal cell carcinoma (BCC) is the most common form of skin cancer; an estimated 2.8 million BCCs are diagnosed annually in the US.³⁸ BCCs are rarely fatal, but can be highly disfiguring if allowed to grow.
• Squamous cell carcinoma (SCC) is the second most common form of skin cancer. An estimated 700,000 cases are diagnosed each year in the US,³⁹resulting in approximately 2,500 deaths.²
• Basal cell carcinoma and squamous cell carcinoma are the two major forms of non-melanoma skin cancer. Between 40 and 50 percent of Americans who live to age 65 will have either skin cancer at least once.⁷
• In 2004, the total direct cost associated with the treatment for non-melanoma skin cancers was more than $1 billion.¹⁴
• About 90 percent of non-melanoma skin cancers are associated with exposure to ultraviolet (UV) radiation from the sun.³⁰
• Up to 90 percent of the visible changes commonly attributed to aging are caused by the sun.¹⁶
• Contrary to popular belief, 80 percent of a person's lifetime sun exposure is not acquired before age 18; only about 23 percent of lifetime exposure occurs by age 18.⁸

Lifetime UV Exposure in the United States
Ages	Average Accumulated Exposure*
1-18	22.73 percent
19-40	46.53 percent
41-59	73.7 percent
60-78	100 percent

*Based on a 78 year lifespan

MELANOMA

• The vast majority of mutations found in melanoma are caused by ultraviolet radiation.³⁶
• The incidence of many common cancers is falling, but the incidence of melanoma continues to rise significantly, at a rate faster than that of any of the seven most common cancers.²¹
• Approximately 68,720 melanomas will be diagnosed this year, with nearly 8,650 resulting in death.³
• Melanoma accounts for about three percent of skin cancer cases,³¹ but it causes more than 75 percent of skin cancer deaths.³²
• Melanoma mortality increased by about 33 percent from 1975-90, but has remained relatively stable since 1990.²¹
• Survival with melanoma increased from 49 percent between 1950 and 1954 to 92 percent between 1996 and 2003.²¹
• More than 20 Americans die each day from skin cancer, primarily melanoma. One person dies of melanoma almost every hour (every 62 minutes).³
• The survival rate for patients whose melanoma is detected early, before the tumor has penetrated the epidermis, is about 99 percent.³⁴ The survival rate falls to 15 percent for those with advanced disease.³
• Melanoma is the fifth most common cancer for males and sixth most common for females.³
• Women aged 39 and under have a higher probability of developing melanoma than any other cancer except breast cancer.³
• Melanoma is the most common form of cancer for young adults 25-29 years old and the second most common form of cancer for adolescents and young adults 15-29 years old.¹⁸
• About 65 percent of melanoma cases can be attributed to ultraviolet (UV) radiation from the sun.³⁰
• One in 55 people will be diagnosed with melanoma during their lifetime.¹⁹
• One blistering sunburn in childhood or adolescence more than doubles a person's chances of developing melanoma later in life.⁴
• A person's risk for melanoma doubles if he or she has had five or more sunburns at any age.⁵

MEN / WOMEN

• The majority of people diagnosed with melanoma are white men over age 50.¹⁹
• Five percent of all cancers in men are melanomas; Four percent of all cancers in women are melanomas.³
• Contrary to popular belief, recent studies show that people receive a fairly consistent dose of ultraviolet radiation over their entire lifetime. Adults over age 40, especially men, have the highest annual exposure to UV.⁸
• Between 1980 and 2004, the annual incidence of melanoma among young women increased by 50 percent, from 9.4 cases to 13.9 cases per 100,000 women.³⁵
• The number of women under age 40 diagnosed with basal cell carcinoma has more than doubled in the last 30 years; the squamous cell carcinoma rate for women has also increased significantly.⁹
• Until age 39, women are almost twice as likely to develop melanoma as men. Starting at age 40, melanoma incidence in men exceeds incidence in women, and this trend becomes more pronounced with each decade.¹⁷
• One in 39 men and one in 58 women will develop melanoma in their lifetime.³
• Melanoma is one of only three cancers with an increasing mortality rate for men.¹⁷

INDOOR TANNING

• Ultraviolet radiation (UVR) is a proven human carcinogen, according to the U.S. Department of Health and Human Services.¹⁰
• Frequent tanners using new high-pressure sunlamps may receive as much as 12 times the annual UVA dose compared to the dose they receive from sun exposure.¹⁰
• Nearly 30 million people tan indoors in the U.S. every year¹²; 2.3 million of them are teens.¹⁵
• On an average day, more than one million Americans use tanning salons.²²
• Seventy one percent of tanning salon patrons are girls and women aged 16-29.¹³
• First exposure to tanning beds in youth increases melanoma risk by 75 percent.¹¹
• People who use tanning beds are 2.5 times more likely to develop squamous cell carcinoma and 1.5 times more likely to develop basal cell carcinoma.²⁰
• The indoor tanning industry has an annual estimated revenue of $5 billion.¹⁵

PEDIATRICS

• Melanoma accounts for up to three percent of all pediatric cancers.²⁴
• Between 1973 and 2001, melanoma incidence in those under 20 rose 2.9 percent.²⁸
• Melanoma is seven times more common between the ages of 10 and 20 than it is between 0 and 10 years.²³
• Diagnoses - and treatment - are delayed in 40 percent of childhood melanoma cases.²⁴
• Ninety percent of pediatric melanoma cases occur in girls aged 10-19.²³

ETHNICITY

• Asian American and African American melanoma patients have a greater tendency than Caucasians to present with advanced disease at time of diagnosis.⁶
• The average annual melanoma rate among Caucasians is about 22 cases per 100,000 people. In comparison, African Americans have an incidence of one case per 100,000 people. However, the overall melanoma survival rate for African Americans is only 77 percent, versus 91 percent for Caucasians.²¹
• While melanoma is uncommon in African Americans, Latinos, and Asians, it is frequently fatal for these populations.⁶
• Melanomas in African Americans, Asians, Filipinos, Indonesians, and native Hawaiians most often occur on non-exposed skin with less pigment, with up to 60-75 percent of tumors arising on the palms, soles, mucous membranes and nail regions.²⁵
• Basal cell carcinoma (BCC) is the most common cancer in Caucasians, Hispanics, Chinese, and Japanese, and other Asian populations.²⁵
• Squamous cell carcinoma (SCC) is the most common skin cancer among African Americans and Asian Indians. ²⁵
• Among non-Caucasians, melanoma is a higher risk for children than adults: 6.5 percent of pediatric melanomas occur in non-Caucasians.²³

"The Effect of Smoking on The Skin" via quitsmokingsupport.com

The Effect of Smoking on The Skin

In 1985, a Dr. Douglas Model added the term "smoker’s face" to the medical dictionary after conducting a study (published in the British Medical Journal) where he found he was able to identify smokers (who had smoked for ten years or more) by their facial features alone. The distinctive characteristics of a smoker’s face which tend to make people look older than they are were called "smoker’s face" and were present in roughly half of the smokers he surveyed, irrespective of the patient’s age, social class, exposure to sunlight, recent change in weight and estimated lifetime consumption of cigarettes.

"Smoker’s Face" was defined as one or more of the following:

a. lines or wrinkles on the face, typically radiating at right angles from the upper and lower lips or corners of the eyes, deeplines on the cheeks, or numerous shallow lines on the cheeks and lower jaw.

b. A subtle gauntness of the facial features with prominence of the underlying bony contours. Fully developed this change gives the face and ‘atherosclerotic’ (sic. A bit like choked up blood vessels) look; lesser changes show as slight sinking of the cheeks. In some cases these changes are associated with a leathery, worn, or rugged appearance.

c. An atrophic, slightly pigmented grey appearance of the skin

d. A plethoric, slightly orange, purple and red complexion different from the purply blue colour of cyanosis or the bloated appearance associated with the pseudo-Cushing’s changes of alcoholism"

"The fact that so many of the people with smoker’s face were fairly young indicate that smoker’s face is not simply a symptom of age. The changes in the colour and quality of the skin suggest a toxic process… In my experience, many people notice the ravages of smoking for the first time when it is pointed out to them that they can be identified as smokers by their faces alone." Dr Douglas Model, British Medical Journal (1985)

What the toxins in cigarette smoke are doing to your skin now!

Cigarette smoke contains more than 4000 toxins many of which are absorbed directly into the bloodstream and are taken by the blood right into the structure of your skin.

Smoking cigarettes reduces the efficiency with which the skin can regenerate itself – smoking causes the constriction (narrowing) of the blood vessels at the top layers of the skin which in turn reduces blood supply (to the skin). It is the reduced blood supply which causes a reduction in the availability of oxygen (which is necessary for all living cells) and the removal of waste products, dead cell fragments etc… which provide the necessary environment for regeneration.

Cigarette smoking causes the blood vessels at the top layers of the skin to constrict and so reducing the oxygen level in the blood there. This thickens the blood and reduces the levels of collagen in the skin (it is actually because of this that smoking is also associated with slow or incomplete healing of wounds).

In fact, smoking a single cigarette can produce cutaneous (pertaining to the skin) vasoconstriction (decrease in the calibre of blood vessels) for up to 90 minutes. One study suggests that blood flow in the thumb decreases about 24% after smoking one cigarette and by 29% after two cigarettes. Another study suggested that digital (finger) blood flow fell by an average of 42% after smoking one cigarette. A further study found that smoking for 10 minutes decreases tissue oxygen tension for almost an hour and concluded that the typical pack-a-day smoker would remain hypoxic* for most of each day. (Smith and Fenske, Journal of the American Academy of Dermatol)

*hypoxic – a reduction of oxygen supply to a tissue below physiological levels despite adequate perfusion of the tissue by blood.

Smoking makes your skin thinner

A recent British study took 25 pairs of identical twins where one twin was a lifelong smoker and the other had never smoked. The doctors used an ultrasound technique to gauge inner arm skin thickness. The smoker’s skin was a quarter thinner than that of the non-smokers and in a few cases there were differences of up to 40 per cent. (Twins study, St Thomas's Hospital)

Facts about Sunscreen!

What is an SPF?
The Sun Protection Factor (SPF) displayed on the sunscreen label ranges from 2 to as high as 50 and refers to the product's ability to screen or block out the sun's harmful rays. For example, if you use a sunscreen with an SPF 15, you can be in the sun 15 times longer that you can without sunscreen before burning. Consumers need to be aware that SPF protection does not increase proportionally with an increased SPF number. While an SPF of 2 will absorb 50% of ultraviolet radiation, an SPF of 15 absorbs 93% and an SPF of 34 absorbs 97%.

How do you select a sunscreen?
With so many brands of sunscreen available, selecting the right sunscreen can be difficult. These tips may help you in making your selection:

Dermatologists strongly recommend using a sunscreen with an SPF 15 or greater year-round for all skin types. If you are fair-skinned and sunburn easily, you may want to select a sunscreen with a higher SPF to provide additional protection. Using a cream, oil or lotion is a matter of personal choice, but keep in mind that most oils do not contain sufficient amounts of sunscreen and usually have an SPF of less than 2. All sunscreens need to be reapplied, so follow the guidelines written on the sunscreen bottle. Gel sunscreens tend to sweat off and, therefore, need to be reapplied more frequently. Remember, expensive sunscreens are not necessarily of better quality.
Choose a "broad-spectrum" sunscreen that protects against UVB and UVA radiation. PABA, or para-aminobenzoic acid, was one of the original ultraviolet B (UVB) protecting ingredients in sunscreens. However, some people's skin is sensitive to PABA, and it also can cause staining of clothing. Today, PABA has been refined and newer ingredients called PABA esters (such as glycerol PABA, padimate A and padimate O) can be found in sunscreens. PABA and PABA esters only protect against UVB radiation, the sun's burning rays that are the primary cause of sunburn and skin cancer. Also look for other UVB absorbers listed in the ingredients such as salicylates and cinnamates.
You should look for a sunscreen that also protects against ultraviolet A (UVA) radiation, those rays that penetrate deeper into the skin and are the culprits in premature aging and wrinkling of the skin. UVA-screening chemicals include oxybensone, sulisobenzone and Parsol 1789, also called avobenzone. NOTE: The SPF number on sunscreens only reflects the product's ability to screen UVB rays. At present there is no FDA-approved rating system that measures UVA protection levels.

Look for a sunscreen that is "waterproof" or "water-resistant," especially if you participate in outdoor physical activity.

Is there a difference between "waterproof" and "water-resistant?"
How well the sunscreen stays on the skin after swimming, bathing or perspiring is just as important as the SPF level. The FDA considers a product "water-resistant" if it maintains its SPF level after 40 minutes of water exposure. A product is considered "waterproof" if it maintains its SPF level following 80 minutes of exposure to water. If you participate in outdoor recreational activities including swimming, you may want to choose a waterproof sunscreen.

What is the difference between sunscreen and sunblock?
Sunscreens can be classified into two major types: chemical and physical. Chemical sunscreens contain special ingredients that act as filters and reduce ultraviolet radiation penetration to the skin. These sunscreens often are colorless and maintain a thin visible film on the skin. These sunscreens usually contain UVB absorbing chemicals and more recently contain UVA absorbers as well.

Physical Sunscreens, most often referred to as sunblocks, are products containing ingredients such a titanium dioxide and zinc oxide which physically block ultraviolet radiation (UVR). Sunblocks provide broad protection against both UVB and UVA light. They can be cosmetically unacceptable to many people, because they are often messy, visible and do not easily wash off. However, some new zinc oxide products are available in brightly colored preparations which are popular with young people. The amount of sun protection these sunblocks provide, while potentially high, cannot be quantified in the same manner as sunscreen SPFs. Physical sunscreen is recommended for individuals who have unusual sensitivity to UVR. Most recently on the sun protection scene is sun-protective clothing designed to block UVA and UVB radiation. The effective SPF is greater that 30.

When should you use a sunscreen?
Sunscreens should be used daily if you are going to be in the sun for more than 20 minutes. Most people will receive this amount of sun exposure while performing routine activities. They can be applied under makeup. There are many cosmetic products available today that contain sunscreens for daily use because sun protection is the principal means of preventing premature aging and skin cancer. Sunscreen used on a regular basis actually allows some repair of damaged skin. Because the sun's reflective powers are great - 17 percent on sand and 80 percent on snow - don't reserve the use of these products for only sunny summer days. Even on a cloudy day 80 percent of the sun's ultraviolet rays pass through the clouds. Skiers beware, ultraviolet radiation increases 4 percent for every 1,000-foot increase in altitude.How much sunscreen should you use and how often should you apply it? You should apply sunscreen to your dry skin 30 minutes BEFORE going outdoors. Pay particular attention to your face, ears, hands and arms. Apply sunscreen liberally using one ounce to completely cover your body. Be careful to cover exposed areas, a missed spot could mean a patchy, painful sunburn. Lips get sunburned too, so apply a lip balm that contains sunscreen with SPF 15 or higher. Sunscreens should be applied in the morning and reapplied after swimming or perspiring heavily. Remember, waterproof sunscreen begins losing effectiveness after 80 minutes in the water, so reapply sunscreen before this time, especially if you have towel-dried for maximum protection.

Client Review!

Check out what one of my clients had to say about Dermaspace and the Iderm Treatment.

THANKS LEILA!!!

http://lbdproject.com/2010/04/08/good-bye-dull-via-iderm/

Did you know....

Did you know that Vitamin C in general is thought an antioxidant that can help refresh skin and reduce the look of aging by promoting new skin growth and destroying free radicals? It's also the main ingredient in the Iderm Treatment process and is Ionized directly through the dermal layer of the skin via a low level of Galvanic electrical current.To learn more - visit www.dermaspace.com.

What is Iontophoresis?

It's the process of introducing water-soluble products into the skin with an electric current. This process allows me to penetrate ions of an applied solution of Vitamin C & Zinc into the deeper layers of the skin with galvanic current.
Ions are atoms or molecules that carry an electrical charge. Current flows through conductive solutions from the positive and negative polarities. This is known as ionization, the separating of a substance into ions. To learn more about how I use this scientific method to give you awesome & flawless skin, visit my website at www.dermaspace.com.
