Li Chujun suggested that middle-aged and elderly people aged 40 to 74 with a high incidence of colorectal cancer should be checked regularly and screened in time. High-risk groups should be more vigilant, such as frequent abdominal distension, discomfort, changes in bowel habits, and repeated blood in the stool. Consider that the hospital does colorectal cancer screening.
Over 40 years old is at risk of cancer
Colorectal cancer is medically called colorectal cancer, which is a collective term for rectal cancer and colon cancer. The occurrence of colorectal cancer has a lot to do with bad eating habits. People who eat high protein and high fat often have more anaerobic bacteria in the intestine, which can decompose bile acid into unsaturated polycyclic hydrocarbons, which is a carcinogen. In addition, the intake of cellulose foods is small, the feces are stored for too long, and carcinogens accumulate, which can easily lead to colorectal cancer.
Li Chujun reminded us to pay attention to the high-risk factors of colorectal cancer: if I am over 40 years old, I have a history of cancer, intestinal polyps, or first-degree relatives (ie father, mother, siblings, children) have a history of colorectal cancer; in addition, if I have Two or more of the following conditions, such as chronic diarrhea that has lasted more than 3 months in the past two years, chronic constipation for more than two months per year; history of mucus or blood in the stool, history of chronic appendicitis or appendicitis, chronic cholecystitis or gallbladder History of resection; major trauma experience in the past 20 years, you should go to the hospital for electronic colonoscopy in time.
Colorectal cancer is often mistaken for hemorrhoids
"Many patients who have blood in the stool often think it is hemorrhoids, and there is no major problem." Yang Zuli said, this is actually a misunderstanding.
Li Junchu talked about a case that impressed him: a 50-year-old lady who has suffered from hemorrhoids for many years and has had blood in the stool repeatedly in recent years, but because of her busy work she did not go to the hospital for examination, thinking that the bleeding was caused by hemorrhoids. Later, I went to the hospital because of the unbearable pain, but the doctor found a tumor in a place close to the hemorrhoids through an anal examination, and finally diagnosed as colorectal cancer.
The common people often say "nine hemorrhoids in ten people". The most common symptom of hemorrhoids is blood in the stool, which is exactly similar to the clinical manifestations of colorectal cancer-colorectal cancer, especially rectal cancer, has no other discomfort except blood in the stool in the early stage.
Blood in the stool is one of the common symptoms of colorectal cancer in the early stage. Because the lesion is close to the anus, the blood color is mostly bright red or dark red. When the amount of bleeding is relatively large, the stool will be brown-red and jam-like. Changes in bowel habits and traits also need attention. Patients with rectal cancer may have more stools, or stools may become thin and deformed; if the cancer grows into the rectal cavity, the stool may be flat and there may be some bloodshot eyes on the stool.
Therefore, patients with blood in the stool, whether they have hemorrhoids or not, should go to the hospital regularly for rectal or colonoscopy. When you find symptoms such as bloody stools that are common with hemorrhoids, you must consider eliminating other diseases of the intestine. In the treatment of hemorrhoids, attention should also be paid to symptoms such as long-term no significant improvement in symptoms or recurring blood in the stool.
Early screening is the most valuable
Compared with other tumors, the occurrence of bowel cancer has to go through the pathological process of polyps, adenomas, and tumors. It takes a longer time to develop from preclinical lesions to tumors. Therefore, early screening is the most valuable for bowel cancer, Li Chujun said. Many malignant tumors that occur in the colon or rectum, if they can be diagnosed and treated early, the effect is very satisfactory.
Although the concept of colonoscopy health examination is gradually being accepted by the public, the situation is still not optimistic. In clinical experience, colonoscopy is performed on a regular basis, most of which are those with better economic conditions and higher social status; those with poorer economic conditions often come to see a doctor when there is obvious discomfort, but it is in the late stage and treatment is difficult The treatment effect is not good and the cost is huge. In fact, the cost of treatment for an advanced patient is enough to do hundreds of early screenings. Li Chujun said that in view of the current people's eating habits and living conditions, the concept of intestinal health inspection should be established. Regular intestinal inspections are beneficial to stay away from colorectal cancer.
Know more about colonoscopy
1. Colonoscopy: ordinary colonoscopy, painless colonoscopy (anesthesia colonoscopy).
2. Preparation before colonoscopy: Thorough intestinal cleansing, so that the examination can be carried out more smoothly and to ensure the accuracy of the examination.
3. Time to take the intestinal cleansing agent: morning examiner: take it the night before examination; afternoon examiner: take it in the morning on the day of examination Those undergoing anesthesia enteroscopy are required to take it 6 hours before the examination.
4. Those undergoing anesthesia enteroscopy must be accompanied by family members, and it is not suitable for driving and working at heights on the day.
5. Eating time after examination: For ordinary colonoscopy, you can eat after the examination; for anesthetized colonoscopy, you can eat after you are fully awake. For those who have undergone endoscopic treatment, the doctor will make an individualized explanation based on the condition.
