https://pmc.ncbi.nlm.nih.gov/articles/PMC5946918/ oh hey here’s a study that goes into the cases when cancer has transferred.
In humans, a lot of things have to go wrong for transmission to happen.
Cancer cells have a parasitic propensity in the primary host but their capacity to transit between individuals is severely restrained by two factors: a lack of a route for viable cell transfer and immune recognition in allogeneic, secondary recipients. Several examples of transmissible animal cancers are now recognised. In humans, the only natural route for transmission is via the haemochorial placenta which is permissive for cell traffic. There are three special examples of this occurring in utero: maternal to foetus, intraplacental twin to twin leukaemias and choriocarcinoma-extra-embryonic cells to mother.
It can also happen in organ transplants, since the recipient has to be on immunosuppressants.

It doesn’t seem like there are case studies about transferring the cancer cells through the air. People can also get diseases that can lead to cancer from each other, but that’s not the same thing.

Possibly it doesn’t bother them when other people do it, but my theory is a very mild sadism.
Probably the rapid pace of eating it plus bad luck. A relative almost died last year because of an intestinal blockage. Don’t know the specific cause of his just one day he couldn’t keep anything down. He went to the doctor thinking it was a bad stomach bug and was immediately shipped off to the hospital for emergency surgery. He lived, but it’s a thing that can very rapidly kill you if you’re unlucky.
Like, people die from stuff that didn’t kill lots of other people all the time. Only one lady died from this:

but dying from drinking too much water, like bowel obstruction, is a known cause of death. Or like when “healthy” athletes randomly die from heart attacks - sometimes the body just goes “nope” and fucks something up. There might have been a flaw in the heart that was just chilling until some slight extra push made it cause a whole system failure.
Maybe the kid had a slightly swollen section of his intestines before he started, or a different flaw in the area, where it was easier for food to get caught. Or he ate it way faster than a normal raw pasta enjoyer would, because it was a challenge and not for the love of raw noodles.
So, I don’t see any reason to doubt it.
