AI Overviews medical advice is facing renewed scrutiny after Google’s AI-powered search summaries were found to give dangerously misleading health guidance, including on cancer care.
AI Overviews under intense scrutiny
Google’s AI Overviews feature, which surfaces AI-generated summaries at the top of Search results, has been accused of offering incorrect and potentially harmful responses to specific medical queries. An investigation by The Guardian found that when asked about diet recommendations for a person with pancreatic cancer, the tool advised avoiding high-fat food, contradicting professional guidance that stresses regular high-fat intake to prevent serious complications.
The probe also highlighted AI Overviews medical advice on liver blood test ranges that ignored critical factors such as nationality, gender, age and ethnicity, risking false reassurance for patients who might actually be outside healthy ranges. Separate queries on women’s cancer tests reportedly produced misleading information that “dismissed genuine symptoms,” raising fears that vulnerable users could delay seeking care.
Google’s response and quiet rollback
According to the report, Google removed the highlighted AI Overviews medical advice responses once the errors became public, and similar summaries no longer appear for some health-related searches tested by journalists. A Google spokesperson said the cited examples came from incomplete screenshots, insisting that AI Overviews links point to well-known, reputable sources.
Critics argue that the prominence of AI Overviews at the top of Google Search means many people will read only the AI-generated text, not the underlying sources, amplifying the impact of any mistake. The true scale of incorrect health information within the system remains unclear, fuelling wider concern among regulators and clinicians.
Healthcare AI race raises stakes
The controversy over AI Overviews medical advice comes as rivals OpenAI and Anthropic aggressively promote healthcare-focused AI products built on customised medical models. These systems are pitched as tools to support clinicians and patients, yet experts warn that even small errors in automated medical guidance can have “dire consequences”.
As powerful models move deeper into healthcare, the AI Overviews episode underlines a stark conclusion: search giants and AI labs alike will be judged not by how fast they deploy medical AI, but by how safely they handle the lives that depend on it.
