Some false claims are dangerous because they are plausible. This one earns its place by being the opposite. At a Republican fundraiser in April 2019, President Donald Trump warned that living near a wind turbine was hazardous in a specific way: "They say the noise causes cancer." [1] There is no "they." There is no study. There is, as best anyone has been able to find, no mechanism by which a turbine's hum could do any such thing.
What the cancer experts say
Go straight to the people whose whole job is cancer. The American Cancer Society, asked directly, said it was "unaware of any credible evidence linking the noise from windmills to cancer." [1][2] When fact-checkers searched the biomedical literature for any study investigating a turbine-noise-cancer link, they came back empty. [1] A 2014 critical review of the scientific literature on wind turbines and health, published in a peer-reviewed medical journal, found no basis for the alarms. [3] PolitiFact rated the claim Pants on Fire, the lowest grade it gives. [4]
Why noise cannot do this
The claim collapses on basic biology. Cancer is, at its root, damage to DNA. Sound is pressure waves moving through air; it does not mutate genes or carry the kind of energy that does. [3] If anything, the relationship runs the other way: certain sound waves are used to image tumors, and researchers are studying whether focused ultrasound can help destroy them. [1] The thing this claim treats as a carcinogen is, in medicine, closer to a tool.
Why a nonsense claim still matters
It is tempting to laugh this one off, and the laugh is earned. The reason to take it seriously anyway is the pattern it belongs to: a public figure inventing a health scare to attack a technology he dislikes, and a slice of the audience carrying it home as fact. Manufactured doubt does not need to be plausible to work. It needs to be repeated. The honest sentence is short: wind turbines do not cause cancer, the people who study cancer say so, and the only noise worth worrying about is the claim itself.
