In daily life, people's daily living habits and the environment are the main factors causing colorectal cancer. People must have regular colonoscopy to understand the health of their colon. Understanding the types and carcinogenicity of intestinal polyps can help to properly remove intestinal polyps and effectively prevent colorectal cancer caused by intestinal polyps . In fact, the precancerous lesions of colorectal cancer are tumor polyps (also known as colorectal adenomas). Statistics show that 80% of colorectal cancers evolve from colorectal adenomas. However, colorectal polyps and colorectal adenomas are two concepts that are not exactly the same. Colorectal polyps refer to raised lesions that protrude from the mucosal surface into the intestinal cavity, which may or may not be pedunculated. Among colorectal polyps, some are tumor polyps and some are non-tumor polyps. Among them, tumor polyps account for 70% to 80% and are closely related to colorectal cancer, while non-tumor polyps, such as inflammatory polyps, hyperplastic polyps, and hamartoma polyps, have little to do with colorectal cancer in terms of their occurrence and development. There are three types of neoplastic polyps: tubular adenomas, mixed adenomas, and villous adenomas. These three types of adenomas are pathologically classified. Generally speaking, most small polyps are tubular adenomas, larger polyps are mixed adenomas, and larger polyps are villous adenomas. Different types of adenomas have different chances of becoming cancerous. Tubular adenomas are lower, mixed adenomas are slightly higher, and villous adenomas are the highest. In addition, the rate of adenoma canceration is also related to size. The rate for adenoma canceration is 1% to 2% for a 1 cm size, 10% for a 1 to 2 cm size, and 40% for a 2 cm size. Generally speaking, the villous adenoma in adenomatous polyps has a high probability of becoming cancerous. If it is not treated, it will 100% become cancerous. Therefore, once the pathological examination finds that the polyp is a villous adenoma, it must be removed as soon as possible. Familial polyposis is a disease that is closely related to genetics and is a precancerous lesion. If no treatment is given, the risk of developing colorectal cancer is very high and must also be actively removed. The above is an analysis of the types and characteristics of intestinal polyps. We hope that readers can improve their understanding of intestinal polyps, pay active attention to colon health on the premise of regular examinations, and eliminate all adverse factors that may cause colorectal cancer.
