The Dangers of Cancer Misinformation

Why Misinformation Spreads

Cancer misinformation thrives because it appeals to emotion. A diagnosis brings fear and uncertainty—and with it, an intense need for clarity and hope. Misinformation often offers simple, reassuring answers, while real medicine is complex, uncertain, and sometimes difficult to accept.

The commercialization of false promises is not new. What’s new is the speed and scale of its spread. As cancer surgeon and longtime pseudoscience debunker Dr. David Gorski explains, misinformation is “way more prevalent now for the same reason other misinformation and conspiracy theories are so prevalent—because they're so easily spread on social media.” False claims gain traction not because they’re true, but because they’re shareable, comforting, or sensational.

The Social Media Amplifier

Support groups and online communities can provide empowerment and connection, but they can also give misinformation a megaphone. Social platforms reward engagement, not accuracy—so misleading content can appear “credible” simply because it is popular. Influencers without medical training and unqualified practitioners further complicate the picture.

A recent analysis published in the American Cancer Society’s CA Journal found that across Instagram, YouTube, and TikTok, 60% of cancer-related content contained inaccuracies. For patients and families, this can lead to wasted time, false hope, harmful choices, and delayed treatment.
