“Even if I eat very lightly, how can I still get bowel cancer?” Mr. Liu, 42, is a native of Guangzhou. He likes to eat morning tea, and his diet is very light. He doesn’t like spicy food. In the past two months, I have always had diarrhea, unshaped stools, and blood in the stool. I went to the hospital for examination and was diagnosed with colon cancer through colonoscopy. The results of the examination shocked Mr. Liu. He felt that only people who liked eating spicy and irritating food would get bowel cancer. However, his diet has always been light, and he could not fight bowel cancer no matter what. In recent years, more and more people have bowel cancer, and many of them are Cantonese. People in Cantonese have a light diet. It is unexpected that they are also a high-risk group of bowel cancer, especially in Guangzhou.
1. Bowel cancer is a disease of the rich and noble, and the incidence rate of Guangzhou people is the highest in the country. According to the Guangzhou Center for Disease Control and Prevention The released data shows that Guangzhou’s colorectal cancer incidence rate ranks first among 31 tumor registries in China. The incidence of colorectal cancer in Guangzhou has reached 34/100,000, and the average incidence of the three central urban areas of Yuexiu, Liwan and Haizhu has even reached 45/100,000, while the incidence of colorectal cancer in my country is only 31/100,000.
In response, Zhi Jiehua, Deputy Chief Physician of the Department of Gastroenterology, Yangzhou First People’s Hospital, Jiangsu said that the high incidence of bowel cancer and the too fine diet, love of roast meat and Often eat late-night snacks related.
A long-term diet that is too refined will lead to a significant increase in the risk of intestinal problems such as constipation and hemorrhoids; and roast pork is a high cholesterol food, and long-term consumption of large quantities will cause gastrointestinal problems. Many “old” Cantonese people also like to eat late-night snacks. Eating these foods at night will lead to excessive intake of fat and protein in the body, will increase the risk of intestinal diseases.
Cantonese people with a light diet are also “favored” by colon cancer. For ordinary people, how should they eat? Remember a principle. Second, how to eat can prevent colon cancer? Harvard Study: 4 Eat Less, 2 More Studies have shown that long-term consumption of a sulfur-containing microbial diet (low-calorie beverages, fried foods, more red/processed meat, fruit and vegetable intake small amounts), or may increase the risk of colorectal cancer.
The study was published in the American Journal of Medicine by Harvard. The researchers selected data from three large prospective cohort studies in the United States for analysis, including 214,797 participants. Among them, men accounted for 22% (46,550), with an average age of 54.3 years; women accounted for 78% (168,247), with an average age of 43 years.
At the start of the study, all subjects were free of inflammatory bowel disease, cancer, and the researchers followed the subjects for an average of 26 years, with all subjects being monitored every 2 to 4 years. The subjects were followed up once to update the colorectal cancer incidence of the subjects.
During the follow-up period, a total of 1.5% (3217) subjects were diagnosed with colorectal cancer. After adjusting for age, family medical history, exercise, weight, etc. After influencing factors, the researchers found that a sulfur-containing microbial diet was significantly associated with a higher incidence of colorectal cancer.
1. The 1/5 subjects with the highest dietary intake of sulfur-containing microorganisms compared with the 1/5 subjects with the least intake:
①Suffering from Colorectal cancer risk increased by 27%.
②The risk of distal colorectal cancer increased by 25%.
③The risk of proximal colorectal cancer increased by 13%.
2. Similar associations were also found in participants of different genders:
①Men had the highest intake of sulfur-containing microorganisms 1/5 had a 45% increased risk of colorectal cancer compared to the lowest 1/5.
②The 1/5 of women with the highest intake of sulfur-containing microorganisms increased by 18% compared to the lowest 1/5 of the subjects strong>. In contrast, the association was more pronounced in men.
In this regard, the researchers analyzed that this is related to sulfur-containing microbial diets increasing the abundance of sulfur-metabolizing bacteria in the gut, which convert dietary sulfur into Hydrogen sulfide may cause DNA damage, destroy the colorectal mucus layer, promote inflammation, and ultimately induce colorectal cancer..
Our daily intake of red meat and processed meat is rich in sulfur amino acids, inorganic sulfur, excessive intake will cause Increased risk of colorectal cancer. Frequent intake of cruciferous vegetables, fruits and other foods is associated with a decrease in the abundance of sulfur-metabolizing bacteria in the gut, and these foods are rich in glucosinolates, which can be hydrolyzed into glucosinolates. >Isothiocyanate, which has a certain anti-cancer effect.
Simply put, if you want to protect your gut health in your life, you should pay attention to drink less processed beverages, eat less French fries, red meat and processed meat, and eat more fresh fruits and vegetables , maintain a balanced diet.
When bowel cancer comes to the door, the body will have a series of abnormal manifestations. If these abnormalities can be caught in time, early detection and early treatment can be achieved, which is very helpful for subsequent treatment. 3. Before the advent of bowel cancer, these symptoms should not be ignored 1. Abnormal stools
Under normal circumstances, the number of bowel movements a day should be 1~2 times , and when the presence of tumors in the intestinal tract causes the intestinal space to be occupied, it will bring adverse stimulation to the intestinal mucosa. Cause the patient to have an abnormal increase in the number of daily bowel movements, and always feel that it is not enough. There may also be diarrhea, alternating constipation, and abnormal bowel patterns (thin strips, flat strips) and other changes, we must be vigilant.
2. Obvious blood in the stool
Intestinal lesions will induce gastrointestinal bleeding, and when the stool rubs against the lesions, it will cause ulceration and bleeding on the surface of the lesions . The blood in the stool caused by colorectal cancer is mainly viscous blood stool with blood on one side, and some patients also have the performance of black stool, which is also the cause of gastrointestinal bleeding. Signal.
3. The frequency of farting is more than usual
If the frequency of farting is abnormally increased recently, and there is a If the smell is obvious, you must be alert. Fart may be related to the location of the tumor. In some patients, the location of the lesion is close to the anus, which may easily cause rectal obstruction, which in turn leads to frequent farting.
4. Abdominal pain
When intestinal lesions cause intestinal obstruction, patients will have obvious abdominal distension, abdominal pain and other symptoms. Abdominal pain is the most common. In general, the pain is located in the middle and lower abdomen, and the pain level will become more and more obvious with the development of the disease, and will gradually evolve from intermittent to continuous.
5. Anal bulge
When the lesion is located near the anus, it will cause bulge and pain in the anus, and the body may also experience abnormal weight loss Performance.
Once you find the above symptoms in your life, you must pay attention and seek medical attention in time. And bowel cancer has a certain “favor” crowd, let’s see if you are on the list.
Fourth, people with high risk of bowel cancer, need to focus on prevention
people with these characteristics on the body , are high-risk groups of colorectal cancer, and need special attention in daily life:
①Positive fecal occult blood;
②The immediate family members have a history of colorectal cancer; He has a history of intestinal adenoma;
④I have a history of cancer and changes in bowel habits. In clinically diagnosed patients with colorectal cancer, more than 90% are evolved from adenomatous polyps. Colonoscopy can detect abnormalities in the intestine, and polyps can be removed and examined under the microscope.
For the above-mentioned high-risk groups of colorectal cancer, regular colonoscopy is recommended, which can not only prevent cancer, but also treat polyps, killing two birds with one stone. In addition, some even if not high-risk groups, but older than 40 years old, are also recommended to have regular colonoscopy.
There is a great relationship between the occurrence of bowel cancer and the daily diet. To prevent bowel cancer, you first need to make changes in your diet. Of course, regular check-ups are also essential.
