Overdiagnosis is recognized as a major harm of mammography and prostate cancer screening – what about colorectal cancer screening?

Professor Michael Bretthauer was the first gastroenterologist to be teleported into a patient's colon in a shrunked version of himself, only to get a better view of the colonic polyps. The sensational event took place during the Felix Burda Award in Berlin this weekend. 


A paper published today in BMJ shows no effect of sigmoidoscopy screening in women aged 60 years and older. This new finding will have implications for a future Norwegian colorectal cancer screening program, where sigmoidoscopy is one of the recommended screening methods.

In an Op-Ed published in the Norwegian daily newspaper Dagens Næringsliv (DN) on November 29, researchers from the Clinical Effectiveness Research group criticize Norwegian private hospital Aleris' offer to women for mammography screening. Aleris actively offers mammography to women outside the recommended screening age and with shorter intervals, a service which is associated with more harm than benefit. The authors suspect Aleris of creating health anxiety in order to maximize profit.

A large portrait interview with Michael Bretthauer reveals insights about his early career in Norway, and how he had to perform a colonoscopy on a world-renowned medical researcher to convince him to join a large study on colonoscopy.   

Endoscopic screening for gastrointestinal cancers has been introduced in many countries. Precise estimates of the magnitude of benefits and harms of endoscopic screening for cancer are a prerequisite for informed decision making for or against participation in screening for individuals in the target population.
