Well the answer to question 2 is available online at cancer.org.  Going by their charts men have a lifetime risk of developing colorectal cancer of 1 in 21 or 4.84% and the odds of a woman catching the same disease is 4.49 or 1 in 22

So even though we know that according to the stats given we eat only 43.4% of a hot dog per day on avg let’s assume for the sake of argument that you actually eat a hotdog every single day for your entire life. what does that do to your cancer odds.
Well if you do the actual math and multiply 4.84/100 by 118/100 it mans that 18% increase makes a man’s odds of getting colorectal cancer  go to 5.7% .  For a woman that 4.49/100 multiplied by 118/100 the woman’s odds go up to 5.2%

In other words, if this study is absolutely positively spot on correct eating that hotdog every single day for your entire life raises your odds of catching colorectal cancer by nearly but not quite….1%.
