Summer Skin Safety Tips to Reduce Skin Cancer


In December of 2010 the results of a landmark study conducted by Adele C. Green, MD were published in the Journal of Clinical Oncology. Dr. Green’s study demonstrated that use of sunscreen cuts the risk of melanoma in half.

This landmark study is the first to use a randomized clinical trial to measure whether sunscreen use was effective in protecting against melanoma. Prior studies had been lab studies or retrospective studies that relied on people’s memory of sunscreen use.


Challenges in conducting a study involving daily defense sunscreen included:


  • The research involved actively working with the subjects (most case-controlled research is done by observing behavior and gathering existing data rather than actively intervening in people’s lives)
  • A placebo could not be used on the control group as this would subject the participants to dangerous levels of radiation.

The first test group was given broad-spectrum sunscreen.


Participants in the first test group were trained how to use daily defense sunscreen.


The second test group (control) was asked to not change their existing habits.


The control group of infrequent sunscreen users was asked not to change their existing habits.

The study was conducted in northern Australia, which is an area of high UV radiation and also boasts the world’s highest rate of melanoma skin cancer. This study allowed the researchers to gather information with minimal intervention, as environmental conditions were already in place. The study included 1600 participants; from 1992 to 1996 subjects used sunscreen as directed by the study, and in 1997 a ten-year follow-up study was conducted. There were 11 cases of melanoma skin cancer in the test group (people who used sunscreen regularly, as directed) and 22 cases of melanoma skin cancer in the control group (people who did not change their sunscreen use habits). This is the first research to provide strong direct evidence that sunscreen helps prevent melanoma.

Summer skin safety tips also include to avoid sun during the peak hours of 10 am to 2 pm, reapplying broad-spectrum sunscreen every 90 minutes or after being in the water, and wearing UV protective clothing for prolonged exposure to UV rays.

Summer vacation can be a fun time for the entire family, but taking precautions will reduce risks of skin cancer for a lifetime.
