Graham said the policy is designed to preserve “the important balance of removing egregiously harmful content while ensuring space for debate and discussion.”

Cancer treatment fits YouTube’s updated medical misinformation framework because the disease poses a high public health risk and is a topic prone to frequent misinformation, and because there is “stable consensus about safe cancer treatments from local and global health authorities,” Graham said.

As with many social media policies, however, the challenge often isn’t introducing it but enforcing it. YouTube says its restrictions on cancer treatment misinformation will go into effect on Tuesday and enforcement will ramp up in the coming weeks. The company has previously said it uses both human and automated moderation to review videos and their context.

YouTube also plans to promote cancer-related content from the Mayo Clinic and other authoritative sources.
