Whether a 0.8cm subtypical polyp of the colon is serious or not depends on the nature of the polyp lesion, if the polyp pathology suggests that it is benign, then it is not serious, and if the pathology result is malignant, then the lesion is more serious. The best way to clarify the nature of the lesion is pathologic biopsy.
Colon 0.8cm subtypical polyp itself generally does not cause special discomfort, but the polyp has the possibility of malignant transformation, you can perform colonoscopic polypectomy, and then the polyp will be sent to the pathology. If the pathology suggests malignant lesions, it is necessary to further improve other tests to determine whether there is metastasis, and then develop a treatment plan. If the lesion is benign, there is no special treatment after the polyp is removed, and regular follow-up colonoscopy is sufficient.
Common pathological findings of polyps include inflammatory polyps, tubular adenomas, choriocarpous adenomas, tubular choriocarpous adenomas, etc. If the lesions are adenomas, it is best to review colonoscopy every six months to determine whether there are new polyps.
