That's Fit blogger Jonathon Morgan wrote on May 25 about five sunscreen myths. In the spirit of Skin Cancer Awareness Month, it seems appropriate to mention this thought-provoking news here on this site.

I just heard a radio commercial about a certain sunscreen, claiming the product is so good consumers need only apply the lotion one time during an eight-hour time frame. It seems, according to the following list of myths, this is not exactly true.

Myth #1: Sunscreens protect all day.
Fact: Regardless of the SPF or what the label says, sunscreens must be reapplied every two hours because active ingredients in most products break down when exposed to the sun.

It feels like summer here in Florida. Our temps topped 86 degrees last week and this kind of heat prompts my little boys to request their favorite summertime activity: swimming.

My kids don't quite understand that the temperature outside is not the same as the temperature of unheated water. And so as soon as warm weather arrives, they dash for their suits and insist we make a trip to the neighborhood pool. I oblige, convinced they'll want to head home once they submerge their piggy toes in pure ice.

But somehow, the temperature doesn't register. They plunge right in, dunk their heads and kick and flop and float. They are happy as clams, quivering lips and all. I am happy too as I watch their joyous moments from the privacy of my lounge chair, tucked away in the shade that borders my kids' perfect playland.

Thanks to chemo, I am the mommy who hides in the shadows during any sunny event. It's been two whole years since my last dose of toxic drugs, but something about the sun and the heat and the residual effects of my infused poison causes my skin to produce red, itchy, unsightly bumps. It happened last year and already this year and I'm wondering now if this will be a life-long nuisance, if I will be seeking shade for the rest of my years.

It's all OK really. Secluding myself from the sun's rays is a pretty healthy venture. And I'm not a real pool enthusiast. Any my boys are old enough to swim independently. And it's peaceful in the shade. So I'm not bitter about this unexpected side effect of chemo -- it's called UV recall -- and I'm not complaining. I'm merely marveling at the power of the drugs that hopefully killed all the cancer in my body, the drugs that seem to creep back year after year, perhaps reminding me that in the whole scheme of things, red, itchy, unsightly bumps are not such a bad life condition.

There's no mystery about how we might help prevent cancer. In fact, we don't even need to venture out of our own minds to figure it all out.

Consider this.

"We estimate that more than 50 percent of cancer incidence could be prevented if we act today on what we already know," says Graham Colditz, M.D., Dr.P.H., and associate director of Prevention and Control at the Siteman Cancer Center at Washington University School of Medicine in St. Louis and Barnes-Jewish Hospital.

And now consider these seven methods for acting on what we already know about cancer prevention.

One. Lose weight and exercise more. It is estimated that 20 to 30 percent of the most common cancers in the United States are directly attributed to being overweight or physically inactive.

Two. Eat right. Plant-based diets help prevent cancer. Eating fruits and vegetables help prevent cancer. Diets high in red meat and animal fat increase the risk of cancer. End of story.

Three. Quit smoking. We all know smoking is associated with lung cancer, but it's also linked to cancer of the colon, kidney, pancreas, cervix, and stomach. Within five years to 10 years, there is a 50 percent reduction in cancer risk for those who stop smoking.

Four. Limit alcohol intake. While a few studies claim there are health benefits to drinking wine and other alcoholic beverages, most data show overconsumption of alcohol increases the risk of oral, esophageal, and breast cancers.

Five. Increase folate intake. Epidemiological studies suggest that low folate levels promote cancer development. Experts recommend taking a multivitamin with folate every day.

Six. Stay in the shade. Limiting long-term exposure to the sun and tanning beds, booths, and lamps minimizes the risk of developing skin cancer.

Seven. Avoid sexually transmitted diseases. Human papillomavirus (HPV) can cause cervical cancer. Hepatitis B and C viruses can cause liver cancer. Helicobacter pylori causes stomach cancer. It's critical that we protect ourselves during sexual contact if we wish to protect ourselves from cancer.

If you live in the northern hemisphere, we are fully into the fall season. In the southern hemisphere, they are enjoying spring, and looking forward to the upcoming summer. To maximize daylight hours, we turn our clocks ahead one hour each spring, and turn the clocks back one hour each fall. However, this has become a bit of a debate in Australia, as Queensland Premier Peter Beattie is digging in his heels, locking his knees, and crossing his arms against his chest in refusing to follow fellow countrymen in Western Australia when it comes to considering the policy of instituting daylight saving time.

Beattie is well-intentioned but ill-informed in his concern that the extra hour of light might increase the already high risk of skin cancer in Queensland. Adding an extra hour at the end of the day -- or the beginning of the day -- depending on how you want to view it, will not increase skin cancer risks resulting from excessive exposure to sunlight. The hours of the day when the sun is most damaging, and most dangerous in increasing skin cancer risks, is the middle of the day from 10 a.m. to 4 p.m.

According to The Skin Foundation, to reduce skin cancer risks, we need to protect ourselves year-round by staying out of the sun during peak hours of 10a.m. to 4p.m., by wearing a broad-spectrum sunscreen with a sun protection factor SPF 15 or higher, wearing a broad-brimmed hat and UV-blocking sunglasses, avoiding the use of tanning parlors and artificial tanning devices, keeping newborns out of the sun, teaching children good sun-protective practices, examining skin from head-to-toe once a month, having a professional examination annually, and avoiding sunburn.

In the past year, I have had three severe skin reactions characterized by red, itchy, burning bumps that start on my chest and without fail climb over my shoulders and onto my back. They last for a few weeks, are irritated by the Florida heat, and have had no known cause -- until today when I visited my dermatologist for a skin cancer screening and briefed her on this bizarre condition that has kept me away from sunscreen and out of the swimming pool and in hiding from the sun. I have suspected that sunscreen, chlorine, the sun -- or some combination of the three -- have been my potential irritants. So I've been avoiding them altogether. But I learned today that the sunscreen and the chlorine are not to blame. That leaves the sun, which is the most likely culprit -- and only because I have received chemotherapy with one very toxic drug. Adriamycin.

My dermatologist told me about a phenomenon called UV Recall that is associated with Adriamycin. Apparently the toxicity of this drug, even though administered long ago, can be recalled, causing a reaction when the UV rays of the sun soak into my skin. Sunscreen may help, my doctor told me, but she cautioned me that it is just a screen -- it does not offer full protection. And she said the best suncreen option would include zinc oxide. I think for me, though, staying out of the sun is my best bet. It's not ideal -- it means I will remain on the fringe of the swimming pool, hiding in the shade, while my boys swim their little hearts out. And tropical vacations will be off my wish list. And I will seek outdoor fun mostly after the sun goes down. But this is okay -- I knew there were long-term side effects of chemotherapy drugs. I am just thankful for now that my heart has not been compromised -- a side effect of both Adriamycin and the drug Herceptin that I have also received. And it's also not a bad thing that the steps I must now take to prevent skin reactions are also the steps that protect me from skin cancer. So in some sort of round-about way, my inconvenient skin issues may just help me stay healthy. And that's just fine with me.

I wish I could reverse the damage I've already done to my skin after too much time spent in the scorching sun, in search of a tan. It's seems unfair that a tan is so temporary -- yet its damage is everlasting. And it seems crazy that so many people are still searching for a tan -- when it has become so clear that is it so harmful.

As many as 60,000 people a year die from too much sun -- mostly from malignant skin cancer -- according to the World Health Organization (WHO). About 48,000 deaths are caused by malignant melanomas, and 12,000 deaths are caused by other kinds of skin cancer. And 90 percent of these cancers are caused by ultraviolet light from the sun. Cancer is not the only side effect of sun exposure, though -- serious sunburn, wrinkling, eye cataracts, growths on the flesh of the eye, cold sores, and other illness can result from the sun.

We all need some sun -- the vitamin D that is produced in the body by the sun helps to prevent disease and immune disorders. But too much is dangerous and sometimes deadly. Yet almost all ill effects from the sun can be prevented. And the WHO has released a report that advises people to seek shade, to use sunscreen with an SPF of at least 15, and to stay out of tanning salons. The report operates under the premise that sunscreens be used not to prolong sun exposure but to protect the skin when exposure is unavoidable.

The bikini turns 60 this month and makes news not just for its birthday but also for its new feature -- a built-in alarm to warn wearers to get out of the sun. Not all bikinis will talk -- but those made by Canadian company Solestrom will. Solestrom has created a new bikini that goes on sale next month with a UV meter built into its belt and an alarm that sounds when it's time to seek shade. The meter on the $190 bikini displays a level of UV intensity on a scale from 0 to 20. Three to five is moderate strength, eight to 10 is very high, and anything above 11 is extreme. A person's sensitivity to UV depends mainly on skin type so this scale operates in general terms.

Despite increasing awareness of the sun's dangers, sales remain strong for the bikini. So Solestrom developed this suit to ease some of the worries about the sun's damaging rays. They have already been met with high demand from Australia and South Africa -- where skin cancer rates are highest. The United States -- now in the loop too -- has about 1 million new skin cancer cases each year.

Sunscreen products containing Mexoryl SX or ecamsule, an ingredient designed to block the sun's harmful UVA rays, have been sold in Canada and Europe for over ten years, but have not been available here.

The Food and Drug Administration (FDA) has recently approved the over-the-counter sale of L'Oreal Anthelios SX sunscreen product containing ecamsule to consumers in the US.

While UVB rays are known to cause sunburn, UVA rays penetrate deeper into the skin and are associated with an increased risk for basal and squamous cell cancers and melanoma skin cancer. Anthelios SX is made by the French cosmetics company L'Oreal. Mexoryl SX is owned by L'Oreal, and is only available in L'Oreal products.

Sunscreens might provide some protection from the harmful rays of the sun, and should be used when going out in the sun. Still your best bet is to shade yourself when spending any length of time in the sun and staying out of the sun during the peak hours of 10 AM to 4 PM when sun can cause the most skin damage.

I confess. I was once a sun worshiper. I grew up in Ohio where a really sunny day was rare -- so on the occasion when the sun was bright and hot, I was in my back yard or at a swimming pool or at a lake soaking up the warmth and comfort of the rays that mostly burned my skin but gave me a glow that eventually turned the slightest shade of tan and made me feel healthy. It's ironic really -- that I felt healthy when the act of sunbathing is so completely damaging. And I knew this at the time and for the many years that followed -- and I still basked in the sun and vacationed in Florida and sometimes actually drove in the direction of the sun on a overcast day, in search of a tan that was never fully achieved because my skin is pale and fair and was never meant for any amount of sun exposure.

Two common misconceptions teens and young adults believe about skin cancer are: “I won’t get cancer from lying in the sun or suntan salons. Why should I worry about something that only affects people over the age of 20 years old?” and "I'll just get skin cancer when I'm old." Kim Clark, 14, melanoma skin cancer survivor, and Jacky Sims, 15, melanoma skin cancer survivor want their peers to understand the factual truth about skin cancer and sun safety.

Inspired by Clark and Sims -- with the help and input of Arizona State University students -- Students Against Melanoma for Shade, SAMS, is a national initiative recently launched to help promote awareness for high school and college students on the dangers of over-exposure to the sun and the importance of sun safety. SAMS will serve as a network for student groups across the country who have an interest in promoting safe sun habits. For individuals and groups who have an interest in raising awareness about skin cancer and sun safety, but lack the financial resources, SAMS would like to hear from you. Visit SAMS for more information.

For sun worshipper Shonda Schilling, being diagnosed with Stage 2 melanoma was an unbelievable shock and a life-changing wake up call to the dangers of too much sun. As a result, Shonda and her husband Curt Schilling -- former Arizona Diamondbacks pitcher -- founded the Shade Foundation in a mission to eradicate melanoma through the education of children and the community in the prevention and detection of skin cancer and the promotion of sun safety.

The Shade Foundation provides shade structures for recreational areas on school grounds, and offers an extensive online resource of educational information and programs to raise awareness for sun safety. According to the American Academy of Dermatology and Shade Foundation, skin cancer is an unrecognized epidemic. Statistically, one in five Americans will develop skin cancer, and the diagnosis of younger adults with skin cancer has increased sharply. Half of all new cancers in the United States are skin cancers.

To be sun safe when going outdoors, they recommend sunscreen, a broad-brimmed hat and sunglasses. And stay away from tanning beds -- because occasional yet intense UVA exposure from tanning beds actually poses a greater risk of melanoma skin cancer than does spending long hours in the sun.
