In the sea of medicine, there is such a shocking case: 14 patients underwent colonoscopy, and the results were jaw-dropping - 13 were diagnosed with precancerous lesions, and 1 was diagnosed with bowel cancer!This is not an exaggeration, but a living reality.
These patients, aged between 52 and 76 years, are all seemingly healthy ordinary people who do not have any abnormal symptoms. However, the results of the examination dealt them a heavy blow.
They were all diagnosed with polyps, which make 90% of colorectal cancers evolve, and Dr. Wang, an experienced endoscopist, recalls the day with a solemn expression.
He said that if these adenomas are removed in time, they will not develop into bowel cancer;But if left unchecked, they will become cancerous one day, only a matter of time.
In this case, we can see the importance of colonoscopy, which is like a mirror that allows us to see what is going on in the intestines and detect and treat possible lesions in time.
Without this mirror, we may miss these lesions, and by the time they develop into cancer, it will already be too late, so the role of colonoscopy is indispensable.
Fear and restlessness
Many people are fearful and uneasy about having a colonoscopy, and they may worry about pain, discomfort or complications during the procedure, or worry that the results may reveal an underlying health problem.
Time and effort
Colonoscopy usually requires a certain amount of time and effort, and patients may need to make an appointment in advance and have bowel preparation before the test, which may require changes in diet and medication use. In addition, the examination process can take a long time and may affect the patient's work and life.
Fees
Colonoscopy usually requires a certain cost, which can be a burden for some people, who may be concerned that the test will be too expensive or that they will not be able to afford other medical expenses that may arise.
Privacy and dignity
Colonoscopy involves the privacy and dignity of the patient, and some people may be concerned about exposing their private parts during the exam, or about being seen or heard by others.
Colorectal cancer, also known as colorectal cancer, is one of the common malignant tumors in China, this cancer often has no obvious symptoms in the early stage, so many patients are already in the middle and advanced stages when they are found, which is difficult and may even lose their lives.
So, are there some ways we can avoid bowel cancer?The answer is yes, that is, early detection, early **.
To achieve early detection and early detection, colonoscopy screening is a very effective method, colonoscopy can directly observe small polyps on the intestinal wall, these polyps are likely to become cancerous if left unchecked.
If polyps are found during colonoscopy and removed in time, polyps can be avoided from deteriorating and thus bowel cancer can occur.
Therefore, it is very important to do a good colonoscopy, through colonoscopy screening, we can detect and ** intestinal diseases early, avoid the occurrence of intestinal cancer, and protect our health. 
Colonoscopy is a very important examination method and is regarded as the gold standard for colorectal cancer screening, through colonoscopy, more than 95% of polyps and cancers can be found, which makes it a very effective means of prevention and prevention.
What's more, 95% of bowel cancers develop from polyps, which means that if polyps can be detected and removed before they become cancer, they can help prevent cancer from occurring.
Li Zhaoshen, an academician of the Chinese Academy of Engineering, once stressed that if a person has not had a colonoscopy before the age of 45, then he should have a colonoscopy as soon as possible.
Because even if you already feel well, you can't know if you have polyps or cancer in your intestines, and a colonoscopy can guarantee that you won't get rectal cancer for the next 5 or 10 years, which is not an exaggeration, but a conclusion based on scientific research and clinical practice.
A recent study in The Lancet, a journal of clinical medicine, revealed the important role of colonoscopy in the prevention of bowel cancer.
The study, funded by multiple UK research institutions for almost 20 years, successfully prevented 35% of colon cancers and saved 41% of patients by examining the lower part of the large intestine, with researchers following 170,000 people for an average of more than 17 years, of whom more than 40,000 underwent colonoscopies.
Colonoscopy is a test method that examines the inside of the large intestine by inserting a tube with a camera, and the results of this study show that colonoscopy can detect and ** lesions in the intestine early, thereby reducing the risk of bowel cancer.
This was also confirmed by a large study in the 2019 Annals of Internal Medicine, which found that the risk of right cancer was reduced by 46% and the risk of left cancer by 72% by reviewing the data of colonoscopy over the past 20 years, so colonoscopy can undoubtedly save the patient's life.
For asymptomatic patients, a colonoscopy should be done when they are over 45 years old, and the most common age for cancer is after the age of 50, so if you want to detect cancer and precancerous lesions early, you must find the trigger before it becomes cancerous.
That is, a colonoscopy before the age of 40, or even before the age of 35, so that we have enough time to eliminate the lesion and prevent and ** cancer.
The relevant content in the "Recommendations for Screening and Prevention of Common Malignant Tumors in Residents" issued by the Shanghai Anti-Cancer Association has sounded the alarm for us, and both men and women should take the initiative to consider colorectal cancer screening once they enter the threshold of 45 years old.
This is not only responsible for one's own health, but also care for one's family and the future, annual fecal occult blood test, and colonoscopy every ten years are important means of early detection of bowel cancer.
Analysis of the disease burden of colorectal cancer in the Chinese population reveals a fact for us: after the age of 50, the risk of colorectal cancer increases significantly, and this cancer is very insidious, and it is difficult to have obvious physical symptoms in the early stage, so it is more necessary to detect it in time through examination.
As we all know, colorectal cancer often evolves from intestinal adenoma, and this process takes 5 to 10 years, so it is important to detect and stifle the germination of cancer early.
Colon polyps are also difficult to detect by symptoms, and in many cases they are detected by surgery or colonoscopy, so it is necessary and critical to have a correct colonoscopy after the age of 45.
Before a bowel exam, you usually need to take a laxative because laxatives can help remove residue and water from the intestines to ensure a clean bowel.
A clean bowel allows for a better view of lesions in the intestine and improves the accuracy of diagnosis, and laxatives are usually taken a few hours before the bowel exam, depending on the doctor's recommendations.
After taking laxatives, patients need to have multiple bowel movements until they pass watery stools, which ensures that the residue and water in the intestines are completely removed.
*Colonoscopy is a kind of intestinal examination that is performed under anesthesia, and the patient does not feel any pain or discomfort during the examination, so it is called "**This type of examination is suitable for those patients who are sensitive to pain or afraid of routine colonoscopy.
Ordinary colonoscopy is a kind of intestinal examination performed in a conscious state, and patients may feel some discomfort during the examination, such as bloating, abdominal pain, etc., but most people can tolerate it.
So, which way is better?There is no absolute answer.
*The advantage of colonoscopy is that the patient does not feel pain or discomfort, but the disadvantage is that it requires anesthesia, there may be certain risks, and ** is relatively high;Although there will be some discomfort in ordinary colonoscopy, it is relatively low and suitable for most people.
Therefore, when choosing, patients should decide according to their specific situation and the doctor's advice, if they are sensitive to pain or afraid of routine colonoscopy, they can choose **colonoscopy;If you are in good physical condition and can tolerate some discomfort, you can choose a general colonoscopy.
Irregular diet
Irregular diet is one of the important factors leading to bowel cancer, and long-term irregular diet, such as overeating and skipping breakfast, will cause adverse effects on the intestines and increase the risk of bowel cancer.
Therefore, we should maintain a regular diet Xi habits, avoid overeating, eat more vegetables and fruits, and reduce the intake of high-fat and high-calorie foods.
Lack of exercise
Long-term lack of exercise can lead to a slowdown in the body's metabolism, slowing down intestinal peristalsis, and increasing the accumulation of toxins and harmful substances in the intestines, thereby increasing the risk of bowel cancer.
Therefore, we should maintain an appropriate amount of exercise, such as at least 150 minutes of moderate-intensity exercise per week, such as brisk walking, swimming, etc.
Long-term constipation
Long-term constipation is also one of the important factors leading to bowel cancer, which can lead to the accumulation of toxins and harmful substances in the intestines, increasing the risk of bowel cancer.
Therefore, we should keep our stools smooth, drink plenty of water, eat more fiber-rich foods such as vegetables, fruits, etc., and seek medical attention in time if constipation symptoms persist for a long time.
