It can be determined whether there is any lesion and the nature of the lesion in the rectum 7- 10 cm away from the anal margin. Many clinical studies have confirmed that 70%-80% of rectal cancer can be found by anal finger examination.
3, fecal occult blood test
Patients with positive fecal occult blood test need further colonography or colonoscopy to reduce missed diagnosis or misdiagnosis of colorectal cancer patients.
4.X-rays
X-rays will show different images after passing through organs and tissues, and some relatively hidden tumors can be shown in X-rays.
5.b-ultrasound
