I think saliva causes cancer.
I can see this as possible. I had my DNA done at MyHeritage a few years ago to see if my dad’s genealogy searches were right. They were.
A family member that I found though the DNA check pointed me to a place called Promethease. You upload your raw data, they analyze it, and tell you what diseases and conditions you are susceptible to from your DNA. Some of the results won’t apply to you unless you have Asian, etc. in your ancestry so you have to weed through it.
Mine was extremely accurate. It said I had a chance of genetic high cholesterol (I do). It also said I was at risk of being an alcoholic. I don’t drink but I have one brother that is an alcoholic. It didn’t find any cancer risks unless I had some Asian DNA (I don’t).
The point of it isn’t to say you WILL have issues but that you MIGHT have issues with some behaviors. It’s like an early warning system.
If they can do that, why can’t they find cancer through DNA?
It’s kind of interesting that we have all of the top medical technology and diagnostic$ now to “ fight cancer” - and cancer rate$ are higher than they’ve ever been.
Though it couldn’t be the ultimate goal of “saliva testing” - it just happens that it’s another pretense it will be an easy way to gather even more individual human DNA.
For that massive DNA database that the WHO - or some other global entity keeps because of ......Covid .....or something.
