What Is The Uv Index

How Many Sunburns Can Cause Skin Cancer?

In order to address the growing concern by Canadians regarding changes in UVR resulting from ozone depletion, Environment Canada rates the UV intensity as UV Index on a scale of 0 to 11+ . It can go to the mid-teens at midday in the tropics. In Canada the UV Index is categorized into low , moderate , high , very high and extreme .

The human health effects and precautions relating to the UV Index are summarized in the following table.

Table 3
Very High
  • Extra precautions required – unprotected skin will be damaged and can burn quickly.
  • Avoid the sun between 11 a.m. and 4 p.m. and take full precautions – seek shade, cover up, wear a hat, sunglasses and sunscreen.
11+ Extreme
  • Values of 11 or more are very rare in Canada. However, the UV Index can reach 14 or more in the tropics and southern U.S.
  • Take full precautions. Unprotected skin will be damaged and can burn in minutes. Avoid the sun between 11 a.m. and 4 p.m., cover up, wear a hat, sunglasses and sunscreen.
  • White sand and other bright surfaces reflect UV radiation and increase UV exposure.

Skin Cancer: Quick Facts From The Surgeon General

Skin cancer is a serious public health concern.

Every year, there are more than 63,000 new cases of melanoma, the deadliest form of skin cancer, resulting in nearly 9,000 deaths.

Skin cancer is the most commonly diagnosed cancer in the United States, with 5 MILLION PEOPLE treated each year.

Treatment for skin cancer costs $8.1 BILLION each year in the United States.

Anyone can get skin cancer. Although those with lighter skin are at higher risk of getting skin cancer, people with darker skin may often be diagnosed with skin cancer at a later stage, making it difficult to treat.

Most skin cancers can be preventedbut we arent doing enough.

More than 1 out of every 3 Americans reports getting sunburned each year. Sunburn is a clear sign of overexposure to UV rays, a major cause of skin cancer.

More than 400,000 cases of skin cancer, about 6,000 of which are melanomas, are estimated to be related to indoor tanning in the U.S. each year.

Tanned skin is damaged skin, yet nearly 1 out of every 3 young white women engages in indoor tanning each year.

Choose sun protection strategies that work:

  • Wear a hat, sunglasses, and other protective clothing, seek shade, especially during midday hours.
  • Use broad spectrum sunscreen with SPF 15+ to protect any exposed skin. Remember that sunscreen is most effective when used in combination with other methods, and when reapplied as directed.

Only Women Who Sunbathe All The Time Get Skin Cancer

This is a big fat myth! Figures show that in 2013, almost 6,000 men were diagnosed with skin cancer compared to just under 5,000 women.

Skin cancer represents 29% of all cancers in women and 31% of all cancer cases in men, so its pretty clear it is not a female-only issue. By 2040 it is estimated that there will be 13,000 females diagnosed and over 20,000 males.

At this time of year, it is surprising if you havent seen magazine ads, commercials, social media ads marketing a sunscreen you should buy to protect you from the sun. Unfortunately, the sunscreens that you are being influenced with are not products that are good for you to use. The focus of selling these products is that you need to lather them on or else you could get skin cancer. However, recent studies have found that sunscreens could be causing more harm than good.

Sunburn And Skin Cancer Facts:

Do Sunburns Cause Skin Cancer?
  • One blistering sunburn in childhood or adolescence more than doubles a person’s chances of developing melanoma later in life.
  • A person’s risk for developing melanoma also doubles if he or she has had five ormore sunburns at any age.
  • The sun exposure pattern believed to result in melanoma is that of brief, intense exposure for example a blistering sunburn – rather than years of tanning.
  • Some people can develop sunburn after less than 15 minutes of sun exposure!

What is Sunburn and what happens to our skin?Sunburn is a reaction to over exposure of UV radiation.The superficial layers of the skin release chemicalsthat cause your blood vessels to expand and leakfluid causing swelling, pain and redness. Withoutsun protection, UV radiation penetrates deep intothe layers of the skin causing damage to the skincells. Skin turns red within 2-6 hours of beingexposed and reaches peak redness after 8-24 hours.It can take several days for the redness to subside.

What You Need To Know About Sunburn

  • Some people are more prone to sunburn: Skin type determines your susceptibility; people with fair skin run the greatest risk. But anyone can get burned.
  • Even without a burn, sun exposure raises skin cancer risk. Even if you are tan or your skin type is dark and your skin does not redden, the sun can cause cellular damage that can lead to cancer.
  • The UV index is a factor: The sun varies in intensity by season, time of day and geographic location. A high UV index means that unprotected skin will burn faster or more severely. Be careful, especially when the sun is strongest. But even when the index is low, the risk remains. Protect yourself every day of the year.
  • You can burn on an overcast day:;Be careful even when the sun isnt shining. Up to 80 percent of UV rays can penetrate clouds.
  • Light pink is still bad: No matter how mild, every burn is a sign of injury to your skin that can result in premature aging and skin cancer.

Uv Radiation And Sunburn

In addition to light and heat, the sun gives out invisible UV radiation. UV radiation can pass through light cloud. It can also be scattered in the air and reflected by surfaces such as buildings, concrete, sand and snow.;The 3 types of UV radiation are UVA, UVB and UVC. The earth’s atmosphere absorbs nearly all UVC radiation before it reaches the ground.;UVA and UVB radiation are both involved in sunburn, but skin reacts differently to each type of radiation:;

  • UVA penetrates into the deeper skin layers and damages the sites where new skin cells are generated. Too much UVA radiation leads to roughening, dryness, blotchiness, wrinkling and sagging of the skin. High doses of UVA radiation can also cause sunburn, damage to genes in skin cells and skin cancer.;
  • UVB is even more dangerous than UVA radiation, causing tanning, burning, ageing, skin damage and significantly promoting the development of skin cancer. It affects the surface skin layer. The skin responds by releasing chemicals that dilate blood vessels. This causes fluid leakage and inflammation better known as sunburn.;

Tanning Facts And Risks

Skin damage starts with your very first tan. Each time you tan, the damage builds up, creating more genetic mutations and greater risk.

Indoor tanning is dangerous: Tanning beds dont offer a safe alternative to sunlight; they raise the risk for skin cancers. One study observing 63 women diagnosed with melanoma before age 30 found that 61 of them thats 97 percent used tanning beds.

Tanning damages all types of skin: Even if your skin type is not fair, tanning causes DNA injury that can lead to premature aging and skin cancer.

You can easily reduce your likelihood of developing skin cancer by practicing sun safety.

Sunburn hurts you in more ways than one. The danger goes far beyond any short-term pain, redness and discomfort, because after the sunburn fades, lasting damage remains.

Sunburn accelerates skin aging and is a leading cause in the majority of cases of;basal cell carcinoma,;squamous cell carcinoma;and;melanoma, the deadliest form of;skin cancer.

Sunburn is bad news, but the good news is that its totally preventable. And the best time to start is today.

How Can Uv Cause Skin Cancer

Too much UV radiation from the sun or sunbeds can damage the DNA in our skin cells. DNA tells our cells how to function. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.

Anyone can develop skin cancer, but some people can have a higher risk, including people who burn more easily.

Staying In The Sun Safely

In order to maintain adequate levels of Vitamin D, it is recommended to stay in the sun 15-30 minutes per day without sunscreen. Start for a few minutes and work up to 30. If your staying out in the sun for longer;wearing a hat and light clothes;would be a good idea to protect the skin from burning. If you are planning to be in the hot sun for longer than 30 minutes, it is a good to have some form a sun protection. If using a sunscreen make sure to use a non-toxic one. I recommend reading the ingredients to see the bottle lists any ones mentioned above.

The EWGs first choice for;sun protection is Zinc Oxide.;It provides full spectrum protection of UVA and UVB rays. Sunscreens like;Earthie Mamas Sunscreen;, are the best choice in sunscreens. There are other reasons why you might want to switch over to a mineral based sunscreen,;You can read more about that HERE.

Eating a;healthy diet;is also important to protect your skin from the sun. A diet high in antioxidant rich foods protects the skin from a sunburn as they act as a protective layer screening the sun from burning the skin. Antioxidants include berries, dark leafy greens, artichokes, green tea, dark chocolate and more.

What Causes Skin Cancer

Skin cancer is the most prevalent form of all cancers in the U.S. and the number of cases continues to rise. It is the uncontrolled growth of abnormal skin cells. This rapid growth results in tumors, which are either benign or malignant .

There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma and melanoma. Basal cell and squamous cell cancers are less serious types and make up 95% of all skin cancers. Also referred to as non-melanoma skin cancers, they are highly curable when treated early. Melanoma, made up of abnormal skin pigment cells called melanocytes, is the most serious form of skin cancer and causes 75% of all skin cancer deaths. Left untreated, it can spread to other organs and is difficult to control.


Ultraviolet radiation from the sun is the number-one cause of skin cancer, but UV light from tanning beds is just as harmful. Exposure to sunlight during the winter months puts you at the same risk as exposure during the summertime, because UVA rays are present in daylight.

Cumulative sun exposure causes mainly basal cell and squamous cell skin cancer, while episodes of severe sunburns, usually before age 18, can raise the risk of developing melanoma. Other less common causes are repeated X-ray exposure and occupational exposure to certain chemicals.

What Can I Do To Reduce My Risk Of Skin Cancer

How Does a Sunburn Cause Skin Cancer?

Protection from ultraviolet radiation is important all year, not just during the summer.

Most skin cancers are caused by too much exposure to ultraviolet rays. UV rays come from the sun, tanning beds, and sunlamps. UV rays can damage skin cells.

To lower your risk of getting skin cancer, you can protect your skin from UV rays from the sun and from artificial sources like tanning beds and sunlamps.

Any time your skin is tanned or burned by the sun, its a sign of damage. Thats why theres no such thing as a safe tan.

The more intense the sun exposure, and the more often you’re exposed, the greater the risk of developing skin cancer.

Skin cancer is the most common form of cancer, affecting 1 in 5 Americans, according to the American Cancer Society. There are several forms of the disease basal cell carcinoma and squamous cell carcinoma, which generally turn up on sun exposed areas of the skin and are the easiest to cure.

Melanoma is the deadliest and most aggressive form. Not all melanomas are related to sun exposure, but most are.

How many sunburns does it take to increase your risk of skin cancer? Is just ONE a danger?

Watch the Ask a Doctor video with Dr. Natalie Azar for the answer.

And dont forget to give yourself a thorough body check, looking for the ABCDEs of skin cancer:

  • A ASYMMETRY One half unlike the other half.
  • B BORDER Irregular, scalloped or poorly defined border.
  • C COLOR Varied from one area to another.
  • D DIAMETER While melanomas are usually greater than 6 mm, they can be smaller.
  • E EVOLVING A mole or skin lesion that looks different from the rest.

Increased Rate Of Aging Of The Skin

Repeated exposure to the sun’s ultraviolet radiation eventually causes skin damage similar to the aging process. Patches of skin become thin and less elastic, and develop blemishes, sun freckles, and wrinkles. These changes may take many years of exposure but when they occur, the damage is irreversible.

Sun Protection/skin Cancer Prevention Tips

Protecting yourself;against the suns damage is the best prevention for skin cancer. You can check the UV index for your area through the;US Environmental Protection Agency.

  • Avoid exposure when the suns rays are the strongest, from 10 am to 4 pm.
  • Wear protective clothing such as a wide-brimmed hat, long sleeves, and sunglasses. These can block out some of the suns harmful rays.
  • Seek out shade whenever possible.
  • Do not use tanning booths or sun lamps these are not a safe alternative to the sun. These emit both UVA & UVB light and;greatly increase risk;for all types of skin cancer.

Prevent Skin Cancer With Sunscreen

So, basically, SPF numbers come from a math equation. Dont worry, I wont ask you to do any math here! Really, what these numbers tell you is how much longer you can soak up the rays before your skin turns red! Its important not to ignore that red glow! Sun damaged skin can show up years later as splotchy spots or even the C word!

Whether its sea or sweat, you should ask about water resistance. This means that your sunscreen keeps protecting after 40 minutes of being in the water. Very water resistant would call for 80 minutes.

In other words, an SPF of 10 would take 10 times the baseline to make your skin red; SPF 20 would take 20 times, SPF 30 would take 30 times and so on.

Did you know, that broad spectrum is the most recommended? What makes it broad is based on the amount of time it takes to darken the skin. Definitely, choose a broad-spectrum sunscreen and apply it frequently.
