Coincidentally, “Big Stomach Witch” Hatsuyo Sugawara also died of colorectal cancer on March 9 this year at the age of 59.
Others include: Brazilian football champion Billy, and senior stunt director Zhu Kefeng who won the Golden Horse Award, all died of colorectal cancer last (2022). Successive deaths of several celebrities due to colorectal cancer have made people pay more attention to the prevention and treatment of rectal cancer while regretting it.
Colorectal Cancer Symptoms
Rectal cancer can be subdivided into colon cancer, rectal cancer or colorectal cancer because of its different location of lesions. Because they are all part of the large intestine, they are collectively called colorectal cancer.
Colorectal cancer is a cancer that occurs in the large intestine (colon and rectum). The large intestine is part of the digestive system and is connected to the anus. Most of the large intestine is made up of the colon, a muscular tube about 1.5 meters long. After the colon absorbs water and salt from leftover food, it passes the waste left over into the rectum, the last 15 centimeters of the digestive system. Stored there and expelled through the anus.
In the early stage of colorectal cancer, there are few subjective symptoms. As the disease progresses, hematochezia, melena, and sticky stools will appear; and then symptoms such as anemia, dizziness, constipation or diarrhea, loose stools, and abdominal distension will appear. Severe cases can cause intestinal obstruction.
High risk factors:
1. Colorectal cancer is mainly concentrated in people over 50 years old, but now there is a trend of younger people.
2. People with a family history of colon cancer are more likely to develop colorectal cancer.
3. The risk of colorectal cancer is higher in people who consume a low-fiber, high-fat diet.
4. People who are sedentary and do not exercise are more likely to develop colorectal cancer.
In addition, people with diabetes, obesity, smoking and heavy drinking are at higher risk of developing colorectal cancer.
caused by living habits
In an interview with The Epoch Times on March 21, Dr. Junko Tokunaga, formerly of the Institute of Medical Sciences at the University of Tokyo, said, “The genetic factors of colorectal cancer are less than 10%, and acquired factors are the main cause. Colorectal polyps are the result of evolution. It is one of the main causes of colorectal cancer. Therefore, if adenomatous polyps can be detected early and removed, the incidence of colorectal cancer can be reduced.”
Dr. Tokunaga said that colorectal cancer is mainly caused by bad living habits. Especially in terms of diet, such as eating foods containing a lot of animal fat and taking less dietary fiber will increase the incidence of colorectal cancer. Obesity, long-term lack of exercise, and bad habits such as smoking and alcoholism are also the main causes of colorectal cancer. But paying attention to diet and exercise in daily life can effectively prevent colorectal cancer.
How to prevent and treat it?
1. rememberTwo more and one less
The Ministry of Health and Welfare emphasizes that “two more and one less” in diet and exercise, that is, more exercise, more fruits and vegetables, and less red meat are the health secrets to prevent colorectal cancer.
exercise more:The risk of colorectal cancer for obese people is 1-2 times higher than that of ordinary people, and 21-25% of colorectal cancers can be attributed to insufficient physical activity, so good exercise habits should be developed.
Many fruits and vegetables:It is recommended to eat 3 servings of vegetables and 2 servings of fruit every day. One serving of vegetables is about half a rice bowl after cooking; one serving of fruit is equivalent to the size of a fist. All kinds of vegetables contain vitamin A, vitamin C, iron, calcium, phytochemicals and other nutrients; the dietary fiber in them can maintain the health of the intestinal tract and enhance the resistance to germs that are waiting for an opportunity to invade.
In 2021, researchers from Harvard School of Public Health and other institutions published a research report on JAMA Network. The researchers followed up 210,000 participants for 26 years and found that those who consumed low-calorie beverages (such as diet cola), French fries, red meat and processed meat, and low intake of fruits, yellow vegetables, whole grains People who eat vegetables, legumes, leafy vegetables, and cruciferous vegetables have a higher risk of colorectal cancer. This type of diet is characterized by an increase in hydrogen sulfide-producing bacteria in the gut. Hydrogen sulfide is a gas that smells like rotten eggs and is one of the main sources of fart smell. Compared with people who ate a diet low in sulfur-friendly microbes, people who ate a diet high in these types of bacteria had a 27 percent increased risk of colorectal cancer.
Less red meat:According to the International Agency for Research on Cancer (IARC), which is part of the World Health Organization, eating 50 grams of processed meat a day can increase the risk of colorectal cancer by 18%. The more you eat, the greater the risk. However, the International Agency for Research on Cancer has not established a safe edible standard range.
2. sun exposure, vitamin intakeD
Liu Chun, a doctor of medicine from the University of Tokyo in Japan, told The Epoch Times that colorectal cancer is a relatively common cancer. In recent years, with the increase of people’s work pressure, the age of colorectal cancer has been declining year by year, and the incidence rate has also increased. risen.
Liu Chun believes that colorectal cancer can be prevented and cured. The key to prevention lies in diet and exercise, and the key to cure lies in early detection. If detected early, the 5-year survival rate of colorectal cancer patients can reach more than 90%.
A Harvard University study found an association between vitamin D and colorectal cancer mortality. Studies have found that vitamin D has anti-colorectal cancer activity. Vitamin D, which is usually obtained from foods such as fish, mushrooms, eggs and milk, can reduce the risk of colorectal cancer in young people.
Liu Chun also said that sunbathing is the most convenient and safest way to supplement vitamin D. 15 minutes of sun exposure, 3 times a week, is sufficient for most people. If sunlight and food cannot meet the needs, dietary supplements should be taken appropriately.
Early colorectal cancer is easy to cure
The National Health Administration of the Ministry of Health and Welfare stated that early colorectal cancer is easy to cure, and the 5-year survival rate is over 90%, but the survival rate of stage 4 colorectal cancer is less than 20%. Since early colorectal cancer is asymptomatic, it can be detected early through regular screening. Therefore, regular screening is necessary to achieve long-term “intestinal” health and safety, so as to achieve the purpose of early detection and early treatment. ◇
