The “primary culprit” of colorectal cancer: Find out this polyp and remove it as soon as possible!
Colorectal cancer: Find out this polyp and remove it as soon as possible!. Colorectal polyps can be roughly divided into two clinically, namely adenoma and non-adenomatous polyps.
Colorectal polyps can be roughly divided into two clinically, namely adenoma and non-adenomatous polyps. Under normal circumstances, non-adenomatous polyps do not need to be overly vigilant, such as inflammatory polyps, hyperplastic polyps, etc., their cancer rate is extremely low, or even negligible, but adenomatous polyps are completely different!
According to clinical statistics, nearly 80% of all colorectal cancer patients in some countries develop from adenomatous polyps!
There are three main types of colorectal adenomatous polyps clinically:
1. Tubular adenoma:
This is the most common type of all intestinal adenomas. It is a type of benign polyp, but it has a certain possibility of canceration. Data shows that the canceration rate of tubular adenomas is about 5% within 10 years. The more tubular adenomas with a diameter of more than 1cm, the greater the chance of later canceration;
2. Villiform adenoma:
Compared with the former, this adenoma has a low incidence rate, but its malignant transformation rate cannot be ignored. It is clinically believed that the more the colorectal adenoma contains the more villous components, the higher the cancer rate. For people suffering from villous adenoma, the cancer rate can reach 30~70% within 10 years;
3. Mixed adenoma:
The so-called mixed adenoma is a polyp that has the characteristics of the above two types of adenoma at the same time. Its cancer rate is between the two, and it can reach about 23% within ten years!
In general, the larger the diameter growth, multiple adenomas, and adenomas containing more villous components, the higher the later cancer rate. In addition to the above three types, there is another type of adenoma that needs to be vigilant. It is: hereditary adenomatous polyposis!
Hereditary adenoma, as the name suggests, is a benign disease related to genetic genes, which is an autosomal dominant genetic disease. When the next generation carries this gene, they may develop the disease in their adolescence. Multiple polyps may appear in the colon and rectum. The number of polyps can even reach hundreds, which is extremely dangerous;
Relevant data shows that if patients with hereditary adenomas have been unable to find the disease or have not undergone scientific treatment, the probability of developing colorectal cancer in the later stage is basically 100%. Hereditary adenomatous polyposis is also the most important factor in the clustering of colorectal cancer families.
According to the current clinical information, people over the age of 45, long-term maintenance of a high-fat, low-fiber diet, a family history of adenoma, and a family history of bowel cancer are at high risk of colorectal polyps. Since colorectal polyps often have no typical symptoms in the early stage, and the patients do not even have any abnormal manifestations, for high-risk groups, colonoscopy screening should be performed regularly!
Once diagnosed as an adenomatous polyp, regardless of its diameter or whether it is multiple, it needs to be removed and treated in time according to the doctor’s recommendation. However, what needs to be emphasized here is that the recurrence rate of intestinal adenomatous polyps is high, so surgical resection is not a one-time-and-for-all operation, and patients need to be reviewed regularly after surgery.
