My dad used baby powder as deodorant because he had sensitive skin. Died of lung cancer at age 58, and never smoked. Anecdotal, but this really pisses me off.

The various facets of all transportation industries probably have as much or more asbestos grinding into the air with particulate matter from vehicular brake systems on trains and automobiles, and to a lesser extent aviation.
The soot in the NYC subway is probably ripe with asbestos. Every time I smell that acrid ceramic smell of new brakes on a subway car, I figure I'm catching a whiff of asbestos, and it's a smell I encounter more than talc.
I only know the smell for what it is from changing brake pads on my car a few times, years ago.
Did NYC somehow get a special “kill all the commuters” exemption under the radar, or something?
There are numerous places online saying that most brake pads no longer use asbestos, particularly OEM brake pads. Though I can't find any numbers to back this up. Also, I have no idea how carcinogenic the replacement materials are; I hope they are less dangerous than asbestos.

You can tell it's working because there's a U-shaped pressure gauge attached to the system showing the differential between under the slab and outside: https://www.clutchprep.com/physics/gauge-u-shaped-tube
People get lung cancer all the time having never smoked.
It's not unreasonable to think there might be a connection.
People don’t seem to realize that there isn’t a cause for every case of cancer. Sometimes you just get cancer even having never been exposed to any risk factors.
EDIT: Removed my qualifier as this directly refutes several child comments.
The size of of the particles on the average might not be small enough to matter, but over time and volume there will be more than a few small particles.
