According to Assoc. Prof. Dr. P Pham Duc Huan, Director of the Center for Gastroenterology, Hepatobiliary Medicine, Vinmec Times City General Hospital, said colon polyps are common and are called precancerous. So which polyps need to be removed?

Classify polyps by size as follows:
Polyps less than 1cm: No possibility of cancer; Polyp 1-2cm: 30% chance of cancer; Polyps over 4cm: 80% cancerous. Assoc. Prof. TS.BS Pham Duc Huan said that polyps should be removed as soon as possible to prevent cancer. To identify cancerous polyps, it is necessary to perform histopathological examination of the entire polyp. However, there are also some signs to identify cancerous polyps based on the size and shape of the polyp. What to do after polyp removal?
With benign polyps, patients need to be re-examined by endoscopy 1, 3 and 5 years. For polyps that have been cancerous, check to see if the polyp has been removed from all cancerous tissue, if it is cancerous, the patient will be assigned surgery to remove the entire cancer. New polyps invading the mucosa: Patients check every 3, 6 months and once a year after removal To prevent colorectal cancer, measures should be taken early such as:
Detect, treat precancerous diseases; Hereditary cancer; Ulcerative colitis bleeding; Specific colitis. Patients with the above signs should be screened for early detection in order to promptly treat and prevent cancer. According to Assoc. Prof. Dr. Pham Duc Huan, the direction of colon polyp treatment depends on the stage of the disease and the location of the tumor in the rectum:
It is possible to cut cancer early by colonoscopy. For cancer still confined to the rectal wall, surgical treatment is the most radical method. For advanced cancer, which has metastasized, it is necessary to combine multimodal treatment: chemotherapy - radiotherapy - surgery.
