The invention relates to the technical field of 
medical treatment, in particular to a colon 
cancer intestinal 
microecology accurate detection, evaluation and intervention 
system and method. The 
system comprises an acquisition unit and a 
cancer evaluation unit, and the 
cancer evaluation unit comprises a 
processing unit and an evaluation establishment unit. The method comprises the following steps: screening and extracting, by the acquisition unit intestinal 
flora of colon cancer patients at different stages and healthy people, and sending extracted 
pathological data to an initial integration unit of the 
processing unit for integration; obtaining biomarkers related to colon cancer in a colon cancer group according to an analysis unit, and obtaining 
flora imaging pictures of the colon cancer group and a 
healthy control group through an imaging unit; and constructing, by a model establishment unit, an accurate evaluation model of colon cancer intestinal 
flora imbalance according to the flora imaging pictures. The method solves the problems that an early colon cancer symptom is not obvious, diagnosis and treatment are easy to cause deviation, and accurate corresponding treatment and prevention cannot be carried out.
