There does not seem to be an effect on overall mortality and colon cancer screening. Generally disease specific markers can be misleading. You really have to wonder what would happen in a well done study of low risk persons being aggressively screened and a control group of low risk persons not being screened at all and followed for 30 years or so and keeping in mind that hospitalizations are a major cause of death.

From the article above:

" This argument does not show that disease specific mortality is better than all cause mortality; indeed, it seems to concede the opposite point. It also assumes that huge trials would show a reduction in all cause mortality, whereas this is precisely what is in question. And it ignores the existing data that strongly support an absence of any effect of screening on all cause mortality, as, for example, in the case of bowel cancer screening."

The japanese in the 80's and 90's achieved a very successfull screaning for the colorectal cancer, and diagnosed many cancers right in the beginning. The screening means early diagbnosis, and early diagnosis for colorectal cancer now (2017) is not see your DNA, but go for coloscopy. For some reason DNA still is not a sure criterion for that cancer.

 

By the way, the japanese have the highest average length of life.

I seriously doubt the Japanese have the highest average life expectancy because they are getting cancer screening.

They have the highest life expectancy (in my oppinion) because of their medicine as general.

 

It is focused on early diagnostics and early treatment. And the society and the politics in Japan go towards profilactics.

 

The early diagnostics of the colorectal cancer there is only one of the reasons for their maximal average lifespan.
