Getting the latest healthcare news for you
Online cancer misinformation is rampant — and it's hurting patients. Research shows up to 42% of top social media cancer content is inaccurate or guideline-discordant, leading to treatment regret and even dangerous self-medication. Experts are now urging clinicians to give patients an "information prescription" — a curated list of vetted, readable resources — to get ahead of the problem.
Cancer patients are turning to the internet and social media in record numbers, but the information they find is often wrong — and the consequences can be serious. Research presented at the COSMO Conference by NYU's Dr. Stacy Loeb found that 42% of the top YouTube videos about prostate cancer and 41% of Instagram and TikTok posts contained inaccurate or guideline-discordant information. Common myths include claims that masturbation causes prostate cancer or that canine dewormers can cure cancer — the latter leading to at least one documented case of severe liver toxicity.
The downstream effects go beyond misinformation. One study found that prostate cancer patients who relied primarily on the internet for information were 46 times more likely to express treatment regret and 83 times more likely to report a worse-than-expected treatment experience. Representation gaps compound the problem: Black men, who face disproportionate prostate cancer risk, were perceived as only 4–9% of individuals featured in top cancer videos.
Key Takeaways:
Why it matters: With nearly 60% of U.S. adults using the internet for health information, the quality and accessibility of online cancer content is a patient safety issue — not just a communication challenge. Clinicians who take a proactive role in guiding patients to reliable sources can reduce harm, rebuild trust, and improve outcomes.
