Bowel cancer screening

Bowel (colorectal) cancer accounted for some 10% of all cancer deaths over 2011 (England and Wales).  

 

Bowel cancer survival is much higher the earlier it is diagnosed.

Yet with this backdrop, a relativley low proportion of these cancers are diagnosed in the earliest stage.

As such, a national screening programme which is aimed almost purely at increasing early detection of such cancers is anticipated to reduce mortality attributable to this cause over the next two decades.

 

It is also worth noting that ultimately this will also depend upon the actual screening uptakeas well as the efficacy of cancer detection at the earliest stage.
