A recent U.S. government publication reports that the incidence rate of melanoma has doubled in the last 30 years. The incidence rates for melanoma, which is a deadly form of skin cancer, are expected to continue to rise with a tripling by 2030

( The report went on to say that in 2011 there were 65,647 reported cases of invasive melanomas of the skin in the United States with a corresponding 9,128 melanoma deaths.


The rise in melanoma incidence rates can apparently be prevented by adopting a national program similar to the successful one in Australia labeled “SunSmart” ( Apparently, much of the success of Sunsmart was and is the result of a successful marketing campaign (that includes a Smartphone app) aimed at changing personal behavior patterns with regard to the sun through public education. The free SunSmart app specifies the times of the day that you need sun protection. In addition to education, the observed desired changes in personal behavior that were achieved were apparently aided significantly by the following clever Sunsmart pneumonic:

  1. Slip on long sleeved clothing,
  2. Slap on a hat,
  3. Slop on sunscreen
    • Sunsmart recommends use of a SPF30 or higher, broad-spectrum, water-resistant sunscreen and lip balm at least 20 minutes before going outside to protect any part of the body that is exposed. Reapplication every two hours is recommended and facilitated by putting a small tube of sunscreen in your jacket pocket or bag. The SunSmart app has a reapplication alert function you can set so you don’t forget to reapply.
  4. Slide on sunglasses and
  5. Seek shade
    • An important part of the Sunsmart program is to take from breaks by going to shaded areas during the middle part of the day.


Two following two important S’s should be added to the five on the Sunsmart skin cancer prevention list above:


  1. Stop trying to get a tan
    • Tanning from UV light, whether it comes naturally from the sun or artificially from indoor tanning salons, not only increases your risk for skin cancer, but also causes skin wrinkles and unattractive skin spots that make you look older. So sunbathing and trips to the tanning salon to get UV treatments should be crossed off your personal behavior list.
  2. Sunburns are deadly
    • Insofar as the relationship between melanoma and sun exposure is concerned the biggest risk factor for melanoma is the number of sunburns one has had – sunburn prevention should be the number priority.
