Not yet investigated
What we have so far
Seven cancers, no safe threshold, and a 2025 US Surgeon General advisory calling for a warning label. Public awareness of the link sits under half.
This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
