Using new technology, the CRCbiome project have examined the feces of over 1000 Norwegians and detected almost 20,000 different viruses, of which two-thirds of the viruses were completely unknown. It turned out that each person had at least 200 different types of viruses in their gut. Many of these viruses were only found in one or two people. Suprisingly we saw a correlation between some of the most common viruses and the participants' lifestyles.
Norway has unfortunately witnessed a high incidence of colorectal cancer, raising concerns about its prevalence. What factors contribute to this situation, and why is this cancer colloquially referred to as 'oil cancer'?
Scientists in the CRCbiome project analyze all the genes in the intestinal contents of thousands of people. The goal is to find new ways to detect early stages of colorectal cancer by using the bacterial flora and machine learning methods.

This Norwegian study (part of the CRCbiome) found no association between moderate amounts of processed meat and colorectal cancer. However, a high intake of red and processed meat was associated with findings of advanced colorectal lesions in FIT-positive colorectal cancer screening participants.
