Would a sun safety app on your phone make you more likely to check your moles or reapply sunscreen every two hours? Developers and the medical community are certainly hoping they will. With the pervasiveness of technology in our everyday lives, it’s not surprising that the battle against skin cancer would take advantage of our dependence on cell phones.
A number of smartphone apps currently available focus on assessing moles for skin cancer and providing guidance on how to check for signs of melanoma. By uploading photos, these apps analyze the moles to calculate the risk of skin cancer depending on the characteristics of the lesions. Several studies, however, have noted that as accuracy can vary, there is a danger that a misdiagnosis may delay medical attention. All apps do specify that they are not intended to replace in-person consultation with a dermatologist or health care professional. The ultimate goal for all, however, is to offer a convenient means for early detection which is key to successful treatment.
Other apps have taken the prevention road for sun safety. In Australia, where sunny climates, outdoor lifestyle, and a beach culture have all contributed to the highest melanoma rates in the world, Cancer Australia funded a trial involving an app which sent text messages to a target group of 18-24 year olds promoting sun protection and reminding receivers to wear sunscreen and encourage them to perform skin self-examinations for early detection. The results of this 12-month study were promising, supporting researchers’ perception that most young adults in that age bracket use cell phones without exception, and electronic communication is second nature. SMS and text messages may just be the natural evolution of Australia’s brilliant “Slip, Slap, Slop” campaign.
Closer to home, a 2012 smartphone app trial in the US involving 600+ participants showed only a slight improvement in sun protection behaviour such as seeking shade, wearing hats and using sunscreen with women more inclined to modify habits than men. Despite availability, the study also pinpointed the biggest obstacle: motivating people to actually use the application.
The real question is whether these apps will be effective in the long-run or be seen as electronic nagging. Will you be tapping download or dismiss?
