    In the past few decades, with changes in diet and longer life span, the incidence and mortality of colorectal cancer (CRC) have been rising sharply, and CRC has now become the second most common cancer in the world

    In healthy adults, the colon contains the densest metabolically active microbial community


    However, it is difficult to integrate and compare different published data because residential areas, medical treatment and technical solutions will strongly affect the changes of human gut microbiota

    Therefore, in order to better understand the mechanism of colorectal cancer and develop more effective CRC screening methods, it is necessary to clarify which of the intestinal bacteria that increase or decrease in colorectal cancer patients are actually involved in CRC.

    Recently, researchers found in two independent cohort studies that 12 taxa of fecal bacteria were enriched in CRC patients

    It is worth noting that the invasion of these bacteria was observed in CRC tissue, which is consistent with the increase in butyrate levels and the signs of aging-related inflammation


    Therefore, these results collectively indicate that there is a causal relationship between the overgrowth of Porphyromonas and the occurrence of colorectal tumors, which may be due to butyrate-induced senescence
