Colon cancer identification
The main points of clinical identification is the length of the disease period, the parasite was detected in the stool, and the morphology and range of lesions seen in the barium enema. One of the most reliable is still through the colonoscopy biopsy.
1、Idiopathic ulcerative colitis
Accounting for 15% of misdiagnosed cases.

5. Schistosomiasis granuloma
Patients with endemic schistosomiasis who have lived in endemic or previously endemic areas have been previously diagnosed with a clear need for colorectal cancer or their own cancers. In addition to line X-ray and fiber colonoscopy and biopsy, combined with the history of schistosomiasis, egg examination in the feces, are helpful colon cancer and schistosomiasis caused by the identification of intestinal
