People over 50 years old who have no family history of colorectal cancer should have enteroscopy every five years; People with a family history of colorectal cancer in their families should have an enteroscopy every three years in order to detect possible precancerous lesions as soon as possible.
Can colorectal polyps cause colorectal cancer? Yesterday, this issue became the focus of the public’s attention in the free diagnosis of colorectal cancer held by the Affiliated Cancer Hospital of Fudan University. Authoritative experts answered this: the precancerous lesions of colorectal cancer are neoplastic polyps. As for general proliferative polyps and inflammatory polyps, they have little relationship with colorectal cancer.
Professor Cai sanjun, director of colorectal surgery at the cancer hospital, pointed out: neoplastic polyps are also known as colorectal adenomas. Statistics show that 80% of colorectal cancers evolve from colorectal adenomas; Among all kinds of colorectal polyps, neoplastic polyps account for 70% to 80%. Judging from the time of canceration, it is a long process for colorectal adenoma to evolve into colorectal cancer, which takes an average of 5 to 10 years. For example, when patients find precancerous lesions, that is, when they find colorectal adenomas, they undergo surgical removal, which not only has little trauma, but also has a very high cure rate.
Experts suggest that people over 50 years old who have no family history of colorectal cancer should have an enteroscopy every five years; People with a family history of colorectal cancer in their families should have an enteroscopy every three years in order to detect possible precancerous lesions as soon as possible.
