YouTube's prostate cancer advice may be dangerous, misleading, says study - Crain's New York Business

Popular YouTube videos on prostate cancer often mislead patients seeking medical screening and treatment information, according to a new study led by researchers at NYU School of Medicine and its Perlmutter Cancer Center.

The study, published Tuesday in European Urology, found that 77% of the 150 most-viewed YouTube videos on prostate cancer contained factual errors or biased content that posed health risks to patients.

One video, for example, promoted injecting herbs into the prostate. The practice can be harmful to patients and is not backed by medical evidence. Other videos were outdated and promoted aggressive treatments not considered necessary, according to the study.

"The real shocking finding for me was this discord between the scientific quality and the user engagement," said the study's senior investigator, Dr. Stacy Loeb, an assistant professor in the urology and population health departments at NYU School of Medicine. "That's really concerning to me as a physician to think that patients and their families are actually more commonly engaging with the content that was biased or misinformative. Just because something gets a lot of thumbs-up, or likes, on a social platform doesn't necessarily mean it's the truth."

The study found that 75% of the videos adequately described benefits of various treatments for prostate cancer, while only 53% of the videos adequately described potential harms and side effects. Average total viewership of the videos studied was 45,000 people, but it ranged as high as 1.3 million people.
