The app saves a photographic baseline of their skin and photograph suspicious moles or other skin lesions and helps the user to apply a skin self-exam step-by-step. The app, UMSkinCheck, sends automatic reminders so users can monitor changes to a skin lesion over time, and provides pictures of various types of skin cancers for comparisons. The app is designed for iPhone and iPad and is available to download on iTunes.

“Whole body photography is a well-established resource for following patients at risk for melanoma. However, it requires a professional photographer, is not always covered by insurance, and can be an inconvenience. Now that many people have digital cameras on their phones, it’s more feasible to do this at home,” says Michael Sabel, M.D., associate professor of surgery at the U-M Medical School, who was the lead physician involved in developing the app.

Every year, nearly two million cases of skin cancer are diagnosed in the United States alone, and about 50,000 will be diagnosed with melanoma, the most serious kind. Regular skin checks can help people discover melanoma in its earliest stages.

The app guides users through a series of 23 photos, covering the body from head to toe. Photos are stored within the app and serve as a baseline for future comparisons. The app will create a reminder to repeat a skin self-exam on a regular basis. If the user notices a change or a growth in a mole, the photos can then be shared with a dermatologist to help determine whether a biopsy is necessary.

“We recommend skin self-exams for everyone in order to detect skin cancer at the earliest stages, when treatment is less invasive and more successful. If you have fair skin or burn easily, have had sunburns in the past or used tanning beds, or have a family history of melanoma, you are considered high-risk, and so it’s even more important,” Sabel says.
