Intestinal polyps are not graded, so intestinal polyps 0.7 cm do not belong to any grade. Intestinal polyps is the intestinal mucosal surface protrudes into the intestinal lumen of the abnormal growth of the class of bulging lesions, divided into non-neoplastic and neoplastic, not to determine the nature of the pathology collectively referred to as polyps; the severity of the polyps according to the size and shape of the polyp, pathology results of the comprehensive judgment, 0.7cm is a larger, need for surgical resection, pathology examination and follow-up treatment. 1. non-neoplastic polyps are: ① hyperplastic polyps, common colorectal polyps, often multiple, the diameter of more than less than 5mm; ② inflammatory polyps, mostly caused by inflammatory stimuli; ③ misshapen polyps and mucosal hypertrophy. 2. Tumor polyps are: ① tubular adenoma, the most common and low cancer rate; ② choriocarcinoma, rare but high cancer rate; ③ tubular choriocarcinoma, also known as mixed type, which has both of the above two types of manifestations, and the cancer rate is between the two. Non-tumor polyps generally have no malignant tendency; adult intestinal polyps are mostly tumor polyps, the diameter of which is larger than 2cm has about half of the cancer rate, and those with a diameter larger than 0.5cm usually need endoscopic treatment and pathological examination. The discovery of intestinal polyps need to be actively examined to clarify the nature of the treatment according to the doctor’s advice, and pay attention to the need for regular review in the future, early detection, early treatment, to avoid the recurrence of adverse effects on the body.
