How to prevent bowel cancer How to prevent bowel cancer?

The exact cause of bowel cancer has not yet been determined, but it is believed that it is related to lifestyle, especially dietary habits. At present, most scholars agree that high fat, high calorie, low fiber and some trace element deficiencies may increase the risk of bowel cancer, and changing the dietary structure may reduce the incidence of bowel cancer. �

According to epidemiological surveys, more than 100,000 new patients with colorectal cancer were diagnosed in the United States in 1988, and more than 80% of them were affected by factors such as environment, lifestyle and diet. Although bowel cancer is a common tumor, its incidence is significantly higher in North America and Europe than in some Asian countries, and less common in Africa. This regional time difference may be related to the fact that western developed countries consume a lot of meat and have the least consumption of coarse grains and vegetables.

However, in Finland, especially in rural Finland, people also consume a high amount of total fat, but the incidence and mortality of bowel cancer are not high. After further analysis, it was found that the high fat in the Finn diet mainly comes from dairy products, which are not only rich in saturated fat, but also rich in calcium. Some scholars have proposed that calcium and vitamin butyl can reduce the incidence of bowel cancer.

In addition, a lack of fiber in the diet is also a risk factor for bowel cancer. Dietary fibre is said to have an inhibitory effect on the development of tumors, which may be due to the fact that dietary fibre increases the bulk of the stool and dilutes the potential carcinogens in the intestinal lumen by allowing the absorbed water. In addition, ingestion of fiber can not only inhibit the secretion of carcinogens into the intestine through the mouth or bile, but also have a protective effect on carcinogens that circulate into the colon epithelium after injection.

If the human body is deficient in trace elements, it can also increase the incidence of bowel cancer. In recent years, some laboratory studies have judged that trace elements have the effect of preventing, inhibiting and reversing tumor processes. For example, selenium, a trace element that is essential for normal cellular metabolism, inhibits tumor induction.

These trace elements, which have the ability to prevent or inhibit tumors, are often referred to as "chemopreventive agents". In fact, a variety of "chemopreventive agents" are abundant in many foods. Citrus fruits and some vegetables, for example, contain high amounts of vitamin C and vitamin E, which block the formation of nitrosamines, which are pain killers.

Removal of the intestines. Guaranteed to be free of bowel cancer.

Develop good habits in your life to prevent bowel cancer. If men want to prevent bowel cancer, they should start by improving their eating habits. Scientifically arrange three meals a day, pay attention to eat more fresh fruits and vegetables, so as to promote gastrointestinal peristalsis.

In particular, the intake of crude fiber foods helps to empty and excrete the stomach and intestines. At ordinary times, the proportion of coarse grains and miscellaneous grains in the staple food can be appropriately increased, and it should not be too fine and too refined; It is necessary to change the habit of eating a diet high in meat and fat; Eat less sweet and greasy foods, especially to control the intake of animal fats, such as lard and fatty meat. Eating large amounts of these foods can promote the occurrence of bowel cancer.

Insist on exercising and paying attention to maintaining a standard weight. People who exercise all year round not only have better physical fitness, but are also less prone to tumors, including bowel cancer.

For bowel cancer, surgery should be considered once the diagnosis is confirmed**. According to the latest technology, if the lesion is small, such as a few tenths of a centimeter, it can be removed endoscopically. For large lesions, most patients still need to undergo first-class surgery.

Depending on the location of the lesion, such as right hemicolectomy, left hemicolectomy, sigmoid resection, etc. In principle, it is necessary to dissect at least 5 cm from the edge of the tumor, plus the surrounding lymph nodes.

Bowel cancer is a very serious disease, and bowel cancer can be achieved through surgery, chemotherapy, and targeted drugs in the early stage, but it is necessary to choose the best way according to the individual's situation, and pay attention to relaxation in the process.

The prevention of bowel cancer is mainly based on diet and exercise. In terms of diet, it is necessary to control the intake of fat and high carbohydrates, and then increase vegetables and fruits, because vegetables and fruits not only increase vitamins, but also increase this dietary fiber, which is conducive to this bowel movement. It is best to have a stool once a day, so that the stool can be excreted from the body in a timely manner, which is not conducive to the accumulation of toxins.

Theoretically, there is no means to prevent bowel cancer, but we say that there is no means to prevent it, and it must not be that there is no bowel cancer, but we still have some means to reduce the incidence of bowel cancer from the perspective of the population. For individuals, it can be said that making this tumor possible may eliminate some high-risk factors. We often use this kind of primary prevention for bowel cancer, and we have some of these terms.

The first one is a low-fat diet. A diet rich in fiber can reduce the incidence of bowel cancer. Second, obesity is a high-risk factor, so proper weight control can reduce the incidence of bowel cancer.

Third, some patients are prone to finding various polyps in the large intestine. If the polyp is found in the colonoscopy, it is also a means to avoid the malignant transformation of the polyp. The fourth is to say that for high-risk groups, such as those with family history, obesity, and one is the high-risk age of about 40 years old, 40 years old or even between 30 and 50 years old, in the high-risk age stage, there are some symptoms such as blood in the stool, irregular stool and some patients, timely regular colonoscopy is an early detection of precancerous lesions, or early detection of bowel cancer, so as to achieve the role of early **, which is also a secondary prevention measure.

Colon cancer belongs to colorectal cancer, and studies have found that there are many risk factors that can lead to colorectal cancer, and the prevention of colorectal cancer can be carried out from the following aspects:

1. From the perspective of diet: some studies believe that fatty diet may lead to the occurrence of colorectal cancer by changing the concentration of bile acid in the stool; In addition, fried and pickled foods are positively correlated with the occurrence of colorectal cancer, and dietary cellulose can protect the colon mucosa by diluting the concentration of carcinogens in the stool, thereby reducing the incidence of colorectal cancer.

2. Patients with colorectal adenoma should be resected in time to avoid the occurrence of colorectal cancer in the future.

3. For patients with digestive tract symptoms, such as abdominal pain, increased frequency of stool, blood in the stool, mucus stool, etc., patients should not easily self-diagnose enteritis, hemorrhoids, etc., and should go to the hospital for timely colonoscopy, and if problems are found, they should be dealt with in time to avoid turning into cancer.

4. Patients who have had a history of colorectal cancer in the past should be re-examined in time, and when the re-examination is found, the problems found should be dealt with in time to avoid the occurrence of new colorectal cancer.

5. Patients with a family history of colorectal cancer should go to the hospital regularly for colonoscopy, in order to detect and deal with the problem in time to avoid colorectal cancer.

6. For patients with ulcerative colitis and Crohn's disease, these two diseases may evolve into cancer if they develop in the long run, so during colonoscopy, if there is a problem, it should be dealt with in time, or even surgically removed, so as not to evolve into cancer.

1. Surgery: Bowel cancer lesions can be removed;

2. Radiotherapy: It has significant efficacy for advanced rectal cancer;

3. Chemotherapy: adjuvant chemotherapy and palliative chemotherapy, adjuvant chemotherapy refers to postoperative chemotherapy, and the chemotherapy time usually starts about 1 month after surgery and lasts for about half a year. Palliative chemotherapy refers to chemotherapy given to patients when they are unable to do so;

4. Molecular targeting**: can be combined with chemotherapy or used alone;

5. Drugs**: such as cetuximab, bevacizumab, etc.;

6. Immunization**;

7. Traditional Chinese Medicine**.

Colorectal cancer is mainly based on surgery, but patients can also choose conservative methods such as radiotherapy and chemotherapy, biology and other conservative methods to control, and also take some anti-tumor drugs for relief, and should also eat more anti-cancer foods such as cabbage and winter melon in the diet, and at the same time pay attention to rest, can not often stay up late and tired, and avoid some strenuous exercise.

If bowel cancer is in the early stage of cancer, it is generally controlled by chemotherapy and drugs, and the chance of survival will be greater if surgery is performed.

Can't regular hospitals? Or is it God, stronger than it?

In general, the prevention methods of colon cancer can be from the following aspects:

First, it is necessary to develop good living habits, which include a balanced diet. Second, don't stay up late often, do some physical exercise, and maintain a healthy and good attitude. Staying up late because of excessive exhaustion and depressed mood may lead to a decrease in immune function, resulting in easy tumors.

Between life and death, it may be the distance of a colonoscopy! Please revisit Professor Jiang Bo's voice at Tsinghua University in June 2017.

It is recommended that the landlord go to the regular, although many of them are now general, but it is still necessary to pay attention to some. Guangzhou Fuda Hospital is good, with rich experience in technology and doctors.

Such a condition is often constipation, which should be surgery**, and postoperative chemotherapy and radiotherapy, which is very painful for the patient.
