That method is not nearly as accurate, right? That's the method her uncle used.

I don't think colon cancer is a genetic/hereditary thing as much as it is you have a diet of mostly meat/processed food
ok 3% of them are inherited
colorectal cancer is caused by an inherited genetic condition called Lynch syndrome, also known as hereditary nonpolyposis colorectal cancer or HNPCC. About 3% (1 in 30) of colorectal cancer cases are due to Lynch syndrome.
