With the improvement of health awareness, more and more people are undergoing regular physical examinations, and the detection rate of intestinal polyps has also increased. Statistics show that more than 80% of colorectal cancers are transformed from colorectal polyps, and the transformation process is mostly normal mucosal development to hyperplasia, then formation of adenomas, and finally cancer. Therefore, intestinal polyps are a “time bomb” that causes colorectal cancer. The most important way to prevent and treat colorectal tumors is to detect and remove them in time before they become cancerous.
It takes 5-15 years for intestinal polyps to become cancer
Intestinal polyps are a very common gastrointestinal disease, and its incidence can increase with age. The clinical manifestations of intestinal polyps are different. There may be no symptoms in the early stage. The general clinical manifestations may include abdominal pain, diarrhea, blood in the stool, mucus in the stool, or accompanied by tenesmus. Polyps vary in size and can be pedicled or broad-based; they can be distributed in a certain segment of the colon and rectum, and can also involve the entire colon and rectum; they can be singly or scattered, or many polyps can be gathered in Together.
Intestinal polyps can be divided into non-neoplastic polyps and adenomatous polyps. Non-neoplastic polyps, especially small polyps with a diameter of less than 0.5 cm, generally do not become cancerous, such as juvenile polyps and inflammatory polyps. Adenomatous polyps are recognized as precancerous lesions and are more dangerous. But don’t worry too much. It usually takes 5-15 years for intestinal polyps to transform into colorectal cancer. This gives us plenty of time to discover and deal with it. Therefore, it is clinically recommended that people over the age of 40 should have a colonoscopy during their annual physical examination. Once a more dangerous intestinal polyp is found, it should be removed as soon as possible to cut off the path of polyp canceration.
Do 3 points to prevent polyp recurrence
According to clinical statistics, patients who have undergone bowel polypectomy have a 28% to 58% probability of recurrence within 3 to 5 years after surgery. Therefore, it cannot be taken lightly after the operation, and it is necessary to prevent it according to its pathogenic factors.
Avoid mechanical stimulation of long-term constipation, the production of intestinal toxins, or the use of irritant laxatives, which can cause intestinal mucosal damage or long-term stimulation of the intestinal mucosal epithelium, leading to localized proliferation of mucosa, glandular epithelium and submucosal tissues, and ultimately the formation of intestinal polyps. Therefore, it is necessary to keep the stool unobstructed and prevent intestinal parasite infection.
The recurrence of intestinal polyps is related to lifestyle habits. If you still eat fatty food after resection, intestinal polyps can also be induced. It is recommended that patients with intestinal polyps should have a light diet, eat less indigestible and irritating foods such as fried, fried, and spirits, and eat more fresh fruits and vegetables. Generally soft and easy to digest food, remember not to drink and smoke, and insist on proper exercise.
Avoid long-term chronic inflammation that stimulates the intestinal mucosa, such as chronic colorectitis, ulcerative colitis, Crohn’s disease, etc., which can cause mucosal erosion, ulcers, connective tissue or granulation tissue formation in the intestinal mucosa, glandular epithelium and The underlying tissue hyperplasia, pathological changes are mostly manifested as inflammatory polyps. Therefore, we must actively prevent and treat intestinal inflammatory diseases.
In addition, the formation of polyps in some people is closely related to genetic mutations and genetic factors, and it is difficult to prevent them through lifestyle. The most common is familial adenomatous polyposis, which is an autosomal dominant genetic disease that can become cancerous if it is not treated. Therefore, those with family history need to strengthen follow-up, be vigilant, and find and treat early.
When it starts to become cancerous, there will be 4 manifestations
Those who have found intestinal polyps and have not undergone surgical treatment temporarily must learn to observe their own symptoms to prevent polyps from becoming cancerous. Generally, once intestinal polyps become cancerous, the body will experience the following discomforts:
abdominal pain and bloating. After bowel cancer appears, intestinal obstruction and intestinal dysfunction will occur. Patients will inevitably feel abdominal pain and bloating, which are mainly concentrated in the middle and lower abdomen. It usually manifests as swelling pain or dull pain, and the symptoms will gradually worsen.
Blood in the stool is usually dark red or bright red because the lesion is closer to the anus, and it is usually separated from the blood in the stool. When the amount of bleeding is relatively large, jam-like or brown-red stools can be seen.
Anemia is caused by long-term chronic blood loss due to blood in the stool. When the function of hematopoiesis cannot meet the compensatory function, the patient will develop anemia.
Changes in stool habits and traits When colorectal tumors grow to a certain size, and infection or erosion occurs, there will be increased stool frequency, changes in bowel habits, unexplained diarrhea and constipation. If the cancer grows toward the rectal cavity, the intestinal cavity will become narrower, and the excreted stool will become deformed and thinner.
