Artificial intelligence is shaking up
industries from software and law to entertainment and education.
And as physicians like Dr. Cem Aksoy are learning, it’s posing
special challenges in medicine as patients tap AI for advice.

Aksoy, a medical ​resident at a hospital in Ankara, Turkey,
says an 18-year-old patient and his family recently panicked
after the young man was diagnosed with a cancerous ‌tumor on his
left leg. They turned to OpenAI’s ChatGPT. The bot said he might
survive only five years.

It was wrong: A plastic surgeon successfully removed the
tumor ​in July. “He was essentially cured after the operation,”
Aksoy said.

But a few weeks later, the patient called Aksoy on the verge
of tears. “He said, ‘I started coughing recently, and ChatGPT
told me it could possibly be metastasis to my lungs,’” meaning
the cancer had spread, the doctor recalled. The patient said he
needed to write a will. It turned out his lungs were fine. He
was coughing because he’d recently started smoking.

“When someone is distressed and unguided,” Aksoy said, an AI
chatbot “just drags them into this forest of knowledge without
coherent context.”

A spokesperson for OpenAI said its newest models have
significantly improved how they handle health questions. ChatGPT
isn’t intended as a substitute for a medical professional’s
guidance, the company said.

The young Turkish patient’s encounter with AI-dispensed
medical wisdom comes as many patients around the world are
turning to the technology for advice. In addition to the big
ask-me-anything chatbots, consumers are turning to a slew of
new, AI-powered consumer medical apps.

‘BECOME ​YOUR OWN DOCTOR’

A growing number of mobile apps available on the Apple and
Google app stores claim to use AI to assist patients with their
medical complaints – even ⁠though they’re not supposed to offer
diagnoses.

Under U.S. Food and Drug Administration guidelines, AI-based
medical apps don’t require approval if they “are intended
generally for patient education, and are not intended for use in
the diagnosis of disease or other conditions.” Many apps have
disclaimers that they aren’t a diagnostic tool and shouldn’t be
used as a substitute for a physician. Some developers seem to be
stretching the limits.

An app called “Eureka Health: AI Doctor” touted itself as
“Your all-in-one personal health companion.” ​It stated on
Apple’s App Store that it was “FOR INFORMATIONAL PURPOSES ONLY”
and “does not diagnose ⁠or treat disease.”

But its developer, Sam Dot Co, also promoted the app on a
website, where it stated in big letters: “Become your own
doctor.”

“Ask, diagnose, treat,” the site stated. “Our AI doesn’t
just diagnose – it connects you to prescriptions, lab orders,
and real-world care.”

Apple said that after learning about Eureka Health from
Reuters, it removed it from its app store. Apple’s guidelines
for developers states that medical apps “must clearly disclose
data and methodology to support accuracy claims.”

App developer Sam Dot didn’t respond to a request for
comment. But the website changed after Reuters inquired ‌about
it. The site no longer mentions the app.

In some cases, apps have given inaccurate and potentially
dangerous advice.

“AI Dermatologist: Skin Scanner” says on its website that it
has ‌more than 940,000 users and “has the same accuracy as a
professional dermatologist.” Users can upload photos of moles
and other skin conditions, and AI provides an “instant” risk
assessment. “AI Dermatologist can save your life,” the site
claims.

Its Lithuania-based developer, Acina, says the app uses “a
proprietary neural network” that looks for patterns to make
predictions. Acina ‍says it was trained on dermatological images
to recognize specific skin conditions.

DERMATOLOGY APP CLAIMS ‘97% ACCURACY’

The app claims “over 97% accuracy.” But it has drawn
hundreds of one-star reviews on app stores, and many users
complain it’s inaccurate.

Daniel Thiberge, a tech-support analyst in New Jersey, told
Reuters that he bought the app to interpret seven pictures he
snapped of a small growth on his arm. Six results showed there
was a “75%-95%” ‍risk it was cancerous, he said. He then went to
a dermatologist. The doctor told him the growth didn’t look
problematic in any way, and it wasn’t worth doing a biopsy.

“If it’s completely, wildly off, what is the purpose of the
app?” Thiberge asked. At best it’s useless, he said. “At worst,
it’s dangerous, because you may not go see a dermatologist.”

In another review on the Apple App Store, a user wrote that
to test the app, she uploaded photos showing she had melanoma, a
serious form of skin cancer, that had been diagnosed and
surgically removed. But the app reported that the condition was
“benign,” wrote the user. She told Reuters that she fears “some
people will trust it and delay doctor visits.”

Reuters didn’t independently confirm the app users’
experiences. Acina said it couldn’t verify them. It told Reuters
that AI Dermatologist’s “purpose is not to provide a medical
diagnosis, but to offer a preliminary analysis using AI
technology to encourage users to consult a professional.”

“Our AI models are built upon dermatological literature and
carefully curated datasets that were selected and validated by
board-certified dermatologists,” it said, adding that “false
positives can happen with any AI system.”

A DOCTOR WORRIES ABOUT APPS’ ACCURACY

The company said its AI has ⁠received many positive online
reviews, including “where users thank us because the app
prompted them to check a mole or lesion early – in some cases
leading to timely medical attention.”

Apple said it removed the app from its App Store after
learning about it from Reuters, in part because of the numerous
customer complaints.

Google also removed ​AI Dermatologist from its Google Play
store after Reuters called attention to the app. “Google Play
prohibits apps from offering misleading or harmful health
functionality and requires regulatory proof or a disclaimer for
apps offering medical functionality,” ⁠the spokesman said.

But the app is back on the market. Google recently
reinstated it after Acina revised it. Google said suspended apps
can return if they’re updated with a “compliant version.”

Acina said it “clarified more explicitly that the app is not
a medical device,” doesn’t provide diagnoses, and that users
should consult healthcare professionals.

Apple also briefly reinstated it, but then removed it again
last week. According to Acina, Apple told it that “upon
re-evaluation,” it determined this: “The app provides medical
related data, health related measurements, diagnoses or
treatment advice without the appropriate regulatory clearance.”
Acina said it is appealing the removal.

Dr. Rachel Draelos, a physician, computer scientist and
consultant in AI healthcare, says AI-powered medical apps are
worrisome, particularly in dermatology. “I’m very concerned by
it ⁠because properly identifying skin things is really hard,” she
told Reuters. There are thousands of skin conditions, and
“there’s no way that all of these apps actually have a dataset
that covers all these things.”
