Say what you will about medicine or alternative therapies -- but I say research, research, research -- and look at everything with a critical eye and cynical perspective. Be determined but never allow yourself to become desparate about any situation you are faced with in life. Because it will keep you more safe than sorry. Here's a cautionary tale I want you to remember.

Thai authorities have arrested an Austrian man, claiming to be a doctor, accused of injecting terminally ill Australians, a New Zealander and other foreigners with bogus chemical cancer cures. Hellfried Sartori, 67, the quack of a doctor who was stripped of his medical license in the 90's and jailed several times in the states, is now being charged with fraud and practicing medicine without a license overseas.

How did the people who came to him to be injected with potentially lethal substances in hopes of curing cancer find him? On the internet! He advertised his ozone treatments on the internet. Not only did he advertise he could cure cancer, but according to investigators, the man said he could cure AIDS, allergies and hardening of the arteries.

According to a news report in the Bangkok Nation, one Australian cancer patient, Kathleen Preston, died last summer in a Thai hospital. An autopsy report found an excessive amount of potassium in her blood. Her death is under investigation.

Celebrities can bring awareness to cancer causes. Celebrities can attract money to cancer fundraisers. Celebrities influence our society in fashion and lifestyle trends. Whether you are one who thinks celebrities have too much influence, and wondering why there seems a global obsession with celebrity -- or you are someone who applauds the efforts of those who have risen to success in fame and fortune and take time to give back, there is no doubting celebrities have power. And even when celebrities aren't trying to make a difference, they do, by the simple fact they are a celebrity.

A news story out of Canada is reporting that young girls, inspired by fair-skinned celebrities like Australian actress Nicole Kidman, are rejecting the fashion standard that a tan makes you attractive and embracing what they are calling the pale and proud of it attitude. When it comes to reducing the rising incidence of skin cancer, this couldn't come as better news. Really good news since it is in the young where a shocking number of new skin cancer cases are being diagnosed, a trend that is fairly recent to our times.

If you don't think staying out in the sun for long periods of time puts you at greater risk for skin cancer -- or that a wide-brimmed hat and sunscreen are all you need to be safe from the damaging rays of the sun -- you might be interested in what MoleMap, a melanoma surveillance program in Australia, discovered during a study of New Zealand farmers and skin cancer rates. I was surprised -- and not in a good way -- by the results of the study.

According to the study, these farmers take sun safety very seriously and observe most of the advised sun safety practices of wearing wide-brimmed hats, sunglasses, protective clothing and sunscreen. Yet, with all those preventive measures, half of the New Zealand farmers, or close family members, have been diagnosed with skin cancer. The unavoidable truth is that the work they do requires them to be out in the sun for as long as eight hours a day.

MoleMap general manager Gavin Foulsham is quoted as saying, "We are getting absolutely hammered with ultraviolet rays from the hole in the ozone layer, and our skies are very clean, so we don't get the protective benefits of pollution either, which ironically caused the hole in the first place." The farmers are being asked to pay close attention to any changes to the skin that could indicate skin cancer and to get it checked right away. For all of us who are not required to work outdoors, this is a cautionary tale of why it is essential to take sun safety seriously and to stay out of the sun for long periods of time.

Admittedly, for years I was a sun worshipper in quest of the perfect golden tan. But I noticed as the years went by the sun was changing, the effects were different, it did not feel as good to be out in the sun for long periods of time. I burned too quickly, tanned far less. I thought it was my imagination, or my age, but I have since learned that the ozone is thinning and the result is an altering in the intensity of the sun's rays. I practice sun safety these days.

When I was telling you about Olay's Bring a Buddy free skin cancer screening campaign, I read a heartbreaking personal story about Dr. Maribeth Bambino Chitkara losing Melissa, her sister, to melanoma at an early age. Who worries about the sun when they are young? I didn't, and most young adults don't. A mole on Melissa's right shoulder had become cancerous, and the cancer had spread to many of the lymph nodes under her arm. Despite treatment, between the two years of skin cancer diagnosis and death, the cancer continued to spread throughout Melissa's body, including her brain. The story, although a very sad one in the loss of a cherished and beloved sister and best friend, I recommend it for reading. The full story can be found here.

May is National Skin Cancer Awareness Month. Become aware and educated about the risks of skin cancer and sun safety. The sun is changing -- the damaging rays increasing in intensity. Even the very young need to be protected, and no one today can afford the risks from a golden tan.

Florida is a sunshine state and dermatologists are concerned about the misconceptions people have about sun safety that are putting them at greater risk for skin cancer. For sun worshippers everywhere, here is the truth about some of the myths:

• Skin cancer is not serious. Skin cancer is very serious and skin cancer diagnosis is reaching epidemic levels in this country. More than one million new cases of skin cancer are diagnosed each year.
• A base tan shields you from sun damage during the summer. Any darkening of skin from the sun is due to sun damage to the skin. Dermatologists state there is no such thing as a safe tan.
• Sunscreen is all the protection needed. According to dermatologists, while sunscreen does offer some protection from the sun, UV rays can defeat the strongest lotion and damage skin.
• Dark-skinned people are safe from sun damage and skin cancer risks. Brown skin with lots of melanin protects better against UV rays, but at the same time, dark-skinned people are more prone than others to have moles, and moles that become abnormal are a major risk factor for melanoma.
• Skin cancer is an age-related disease of the middle-aged and elderly. Yes, the chances of being diagnosed with cancer does increase as we age. But dermatologists say the number of young adults and even children with skin cancer appear to be rising faster than it is for adults now. The depletion of ozone in the atmosphere is letting in more UV rays.
• Tanning salons are safer than the sun. Tanning booths can be more damaging to the skin because they use pure ultraviolet light.
  

For information on how to practice sun safety, read skin cancer prevention kits for kids, shading kids from the sun, global warming skin cancer warning, and pediatricians need to educate parents about sun exposure risks.

The Environmental Protection Agency has created the SunWise School Program and SunWise Kids, as an environmental and health education program offering teaching tools for schools, communities and kids in learning about sun safety. From building shade structures to sun protection advice, the program is designed to appeal to kids.

The SunWise Kids website lets kids know the skin cancer risks caused by too much sun exposure and how to protect themselves from sun damage. Kids will find a trivia game and action steps to take to be sun safe. There is the Survivor's Challenge and SunWise Action Steps. In addition, there is a UV Index scale that allows kids to learn more about each UV level. The SunWise Kids website resource includes an educational area on the ozone layer that explains how we got to where we are in the increased dangers of sun exposure.

If a school joins the SunWise Program and orders a UV meter, they will receive the SunWise toolkit that includes activities and a UV sensitive Frisbee that changes color when exposed to the sun. With the meter kids can measure how much UV radiation reaches their town. Kids can enter the UV information on the SunWise web site. Then they can look at the data and compare UV numbers with the National Weather Service's UV Index. For more information, go to SunWise Kids.

Environment Canada meteorologists are warning people who enjoy spending time in the sun to do less so this year. As the ozone layer continues to thin, the danger for sunburn, cataracts and skin cancer continues to increase. The ozone layer is not protecting us from the sun's harmful ultraviolet radiation as much as it once did.

According to Environment Canada, the ozone layer across Canada has decreased by four to eight per cent over winter and spring, and the more sunny days there during the summer season, the more skin cancer risk to those who spend time outdoors.

Counting on sunscreen lotion to protect from the damaging rays of the bright day sun is no longer sufficient. Skin cancer experts insist, to be safe, stay out of the sun from 10 a.m. to 4 p.m. -- if you must be outside -- stay in the shade. Wear a wide-brimmed hat and quality sunglasses that offer protection from UVA and UVB radiation, and a long-sleeved shirt. Gone are the care-free days of walking out the door in shorts and a summer top, to spend the day enjoying the warmth and brightness of a summer day. Or, for sun worshippers, a day basking in the sun to achieve the golden tan.
