Choroidal adenomas are more serious and usually require surgery. Chorionic adenoma is a common pathological type of colorectal adenomatous polyp, which is a benign tumor, but belongs to a kind of precancerous lesion with high cancer rate. Once the diagnosis of choriocarcinoma is confirmed, it is recommended to have timely surgical treatment, and further biopsy after surgery to exclude the possibility of cancer can be done without other treatments for the time being. Regular colonoscopy is needed to avoid recurrence of polyps, and once recurrence occurs, surgery should be continued so as to avoid the occurrence of choriocarcinoma. If choriocapillary adenoma is left untreated, some patients may develop cancer, with the cancer rate greatly exceeding that of patients who do not have colorectal polyps. Early detection and treatment of choriocapillary adenoma in the clinic is key, and once detected a doctor will need to develop a treatment plan.
