Let’s say, for instance, someone with lung cancer coughs, and a few cancer cells are present in the aerosol, and is breathed in. Or, if someone has a cut, and lives with a family member who has cancer, and cancer cells end up in the cut.
Cancer cells are a bit like HIV in that they evade the immune system by releasing some chemical to trick it. Hence why in an infamous unethical experiment after the war, people injected with another person’s cancer developed cancer. So even if it is another person’s cancer cells, the cancer will metastasize in the body.
This would make cancer the most overlooked infectious pandemic in all of human history.
You say that like it wouldn’t be considered unethical to prove it by today’s standards. The shower thought is that could it be this is at least part of the reason why cancer rates are increasing.
It wasn’t considered ethical in Southam’s day either. He was found guilty of fraud, deceit, and unprofessional conduct related to the experiment you’re citing.
Those experiments didn’t prove anything. There is a 0.00% chance that cancer rates are increasing because cancer is actually airborne and contagious. It’s not just stupid for you to be saying something like that, it’s irresponsible.
A few decades ago op would be going on about how they’re so sure that aids can be contracted from a toilet seat. That nonsense badly set back research.
This kind of disinformation can cause discrimination against those battling cancer and cancer survivors.
The likely cause if increased cancer rate is the increased consumption of ultra processed foods.

And better detection methods.
Very true!
