Nearly 9,500 Americans are diagnosed withskin cancerevery day and about 1 in 5 people in the United States will have it in their lifetime.

In April 2023, the U.S. Preventive Services Task Force (USPSTF)updated its 2016 recommendationon skin cancer screening to state that there’s still not enough evidence to be definitely “yay” or “nay” when it comes to having healthcare providers do visual skin checks on teens and adults who do not have symptoms or risk factors.

However, since many skin cancers go undetected (and therefore undiagnosed), it’s important to be proactive about learning the signs and knowing your risk.If you have a smartphone, there are some digital tools you can get started with on your own.

For example:

While many apps claim to spot skin conditions—including cancer—here’s what experts want you to know about skin cancer and whether you should use these apps to screen yourself.

How Can You Tell If It’s a Mole or Skin Cancer?

How Do Skin Cancer Apps Work?

Most skin detection apps have a user take a picture of their skin or upload pictures,Vamsi Varra, MD, a resident physician in the Department of Dermatology at The Ohio State University College of Medicine, told Verywell.

Varra said that some of the apps also ask questions about the user’s skin problem, such as how long it has been there, whether it has grown, and if they are having other symptoms.

Many of the apps then refer to a database of images and use an algorithm to identify the most likely diagnosis,Melanie Palm, MD, a board-certified dermatologist atArt of Skin MD, told Verywell.

It’s important to note, however, that skin-detecting apps can vary in how they work. Some require more information from users than others and have different ways of analyzing and detecting skin issues.

Are Skin Cancer Apps Reliable?

Although some developers of skin cancer apps claim the tech can identify problematic skin lesions and issues, experts say these apps may not always be accurate.

“There are definitely uncertainties and improper diagnosis that arise from various apps,” Palm said. “I would not rely solely on an app to diagnose and reassure myself that a spot isbenign.”

Palm has seen many cases where a skin lesion may look completely benign (that is, not cancerous), but after a biopsy and microscopic evaluation, it turns out to be something unusual like amelanoticmelanomaorMerkel cell carcinoma.

Research also seems to back up the questionable accuracy of the apps:

Varra said that since these apps have not been studied much in medical settings, it is hard to tell if they are reliable.

“Just like any other medical device, they should undergo appropriate testing and receive FDA approval before being used regularly for medical purposes,” he said. “At this point, they haven’t been sufficiently validated and have the potential to harm patients if they miss skin cancer diagnosis.”

Do Dermatologists Recommend Apps?

While apps can be a first step in figuring out what might be going on with your skin, experts do not necessarily recommend using them because they can provide a false sense of security or even an incorrect diagnosis.

For now, Varra would not recommend that people use apps to decide whether to see a dermatologist or to screen for skin cancer. If you have a lot of skin lesions, turning to an app could be especially unhelpful.

“There is a high chance [an app] will mistake a benign lesion for a dangerous lesion, causing unnecessary worry,” he said.

Palm said that if you decide to try out the apps, understand that the tech should not replace seeing a specialist (like a dermatologist) for an evaluation.

How Deadly Is Skin Cancer?

When Should You See a Dermatologist?

Varra added that patients with lesions that are new, changing quickly, growing, or painful should also see a dermatologist.

“While many benign skin lesions can have these features, they are possible indicators of a dangerous skin lesion,” he said.

Palm added that if you notice skin lesions that follow any of the ABCDEs of melanomas—changes in asymmetry, border, color, diameter, or evolution—you need to see a board-certified dermatologist.

What This Means For YouWhile skin apps can be a rough screening tool, experts say that the tech is not perfect and should not be used to diagnose a skin lesion that’s concerning to you. It is always best to see a board-certified dermatologist if you are worried about your skin health.
