OVERVIEW

Overview

Colorectal tumors are various kinds of tumors that occur between the cecum and the anus, as well as neoplastic lesions that are closely related to colorectal tumors and so on. Colorectal tumors can be divided into two categories: benign and malignant. Benign colorectal tumors can be divided into colorectal polyps and colorectal polyposis; malignant colorectal tumors mainly refer to colorectal cancer, colorectal smooth muscle sarcoma, colorectal fibrosarcoma, colorectal malignant lymphatic system tumors, carcinoid tumors, and so on.

Whether medical insurance

Yes

Department

Oncology, Basic Surgery

Clinical Symptoms

Changes in bowel habits and fecal character, abdominal pain, lower abdominal mass, etc.

Hazards

Malignant tumors may metastasize to distant places via lymphatic or bloodstream route, which may be life-threatening.

Complications

Intestinal obstruction, intestinal perforation, intestinal bleeding, etc.

Examination

Blood routine, blood biochemistry, stool routine, fiberoptic colonoscopy, pathology and histology.

Diagnosis

Preliminary diagnosis can be made on the basis of symptoms such as change in bowel habit and fecal character, combined with colonoscopy.

Treatment principle

Benign tumors are mainly treated by surgery; malignant tumors are treated by surgery, chemotherapy, radiotherapy, traditional Chinese medicine and other comprehensive treatments.

Curability

Most of benign tumors can be cured after active treatment; malignant tumors can be cured in early stage, but the curability is low in late stage.

Dietary advice

Diet should be diversified, with foods rich in vitamins, avoiding too rough, smoky and fried foods.

Causes

Epidemiology

The age of onset is 40 to 50 years old, and males are more common.

Diagnostic basis

The benign or malignant nature of the tumor can be clearly diagnosed according to the symptoms such as change of bowel habit and fecal character, abdominal pain, lower abdominal mass, combined with laboratory tests such as fecal routine + fecal occult blood, fibro-colonoscopy, pathological and histological examination.

Treatment

Treatment guidelines

Benign tumors are mostly treated with surgery; malignant tumors are treated with a comprehensive treatment plan based on surgical resection.

Radiotherapy

Malignant tumors are supplemented with radiotherapy after surgery to improve the prognosis of the tumor.

Surgery

Surgery is generally advocated for benign cases to remove the tumor.
