New saliva test will tell you in 10 mins. if you have cancer

Interesting. I would be too freaked out to try this probably though.

I would almost rather get a doctor's diagnoses and recommendation, if I did have to get bad results, instead of winging it on my own for the results. The doctors would probably want to run all the tests again anyway.

I suppose if you were waiting for results and didn't want to wait, this would be an easy answer though.
