60% of patients are diagnosed at an advanced stage
Colorectal cancer is the second most deadly cancer in Hong Kong, and it has become younger in recent years. Some doctors cited studies that in recent years, the number of young patients diagnosed with colorectal cancer has increased, and 60% of the patients were diagnosed at an advanced stage and the condition was serious. Colorectal cancer is related to eating habits. There is one type of diet that increases the risk, among which refined grains, such as white rice, are one of the high-risk factors for colorectal cancer.
60% of colorectal cancer patients are diagnosed at an advanced stage
Taiwanese retired cardiologist Xie AnminFacebook pagePublished an analysis of two studies on colorectal cancer. According to a study published by the American Cancer Society last week, among newly diagnosed patients with colorectal cancer in recent years, from 1995 to 2019, the number of people under the age of 55 nearly doubled, from 11% to 20%. In 2019, 60% of patients with colorectal cancer were diagnosed at an advanced stage.
In 1995, when cancer screening was not popularized, only 57% of patients were diagnosed with advanced cancer. After screening became more popular around 2005, the rate of late diagnosis dropped to 52%. However, the researchers still have not found the reason for the younger patients and the increase in the number of advanced patients.

1 way of eating increases the risk of colorectal cancer
Dr. Xie Anmin quoted another study that Western diet can easily lead to colorectal cancer. The researchers invited 130,000 people to participate in the study. Participants came from two large studies of health workers (Health Professionals Follow-up Study and Nurses’ Health Study; Nurses’ Health Study).
After analyzing their health status, the researchers found that 1,175 of them had colorectal cancer, and 111 of them had a special type of Escherichia coli (E. Coli) in their colorectal cancer cells, which increases the risk of colorectal cancer .
The researchers also analyzed their eating habits and found that most people who followed a Western-style diet were more likely to have this bacteria in their intestines. The researchers pointed out that the Western-style diet may change the bacterial ecology in the large intestine, resulting in the production of special bacteria that stimulate intestinal inflammation and eventually lead to cancer.
4 types of food are easy to cause colorectal cancer, and eating white rice is also high risk?
Dr. Xie Anmin quoted the above research and pointed out that this Western-style diet can cause inflammation in the whole body and gastrointestinal tract (inflammation). The Western-style diet mainly includes the following 4 types of food:
The researchers list the main foods on the Western-style diet:
Refined grains (eg: rice)
Red meat (beef, pork)
Processed meats (bacon, ham, sausage, bacon, etc.)
Western-style diet less vegetables, beans may increase cancer risk
Xie Anmin said that the above studies prove that diet is related to colorectal cancer, and Western diet is more likely to increase the risk of colorectal cancer. He also reminded that although most Chinese diets are mainly Chinese or a mixture of Chinese and Western foods, there are still a lot of red meat, processed meat, sugar and refined grains in their daily food that are similar to Western diets. Eat less vegetables and beans, so pay more attention to the prevention of colorectal cancer.

According to the Hong Kong Department of Health, most colorectal cancers start from a small polyp. Polyps are usually benign, but some can slowly turn into cancer, which can take 10 years or more. If not treated early, cancer cells can invade and destroy nearby organs, and can spread to other parts of the body through the blood and lymphatic system.
Colorectal cancer may not have any symptoms in the early stage of the disease, but the symptoms are often similar to other intestinal diseases. Common symptoms are as follows:
5 common symptoms of colorectal cancer
An unexplained change in bowel habits (diarrhoea or constipation) that persists for more than two weeks
bloody stools or a lot of mucus
Still want to have a bowel movement after defecating
Abdominal discomfort (persistent pain, fullness, or cramping)
Unexplained weight loss and tiredness

Qian Zhenghong, a gastrointestinal hepatobiliary doctor, said that the cause of colorectal cancer is closely related to diet and living habits. Among the 16 risk factors, 3 are related to diet. Dr. Qian pointed out that the following 8 factors are more likely to cause cancer risk:
People with a large abdominal circumference (fat belly) are especially at risk. Men with a waist circumference greater than 100 cm/ women with a waist circumference greater than 95 cm have a 53% increased risk of colorectal cancer, and a 45% increased risk for people with a BMI over 29.
2. Eat processed or red meat a lot
Processed food contains nitroso compounds, while meat cooked at high temperature will produce carcinogens such as isocyclic amines and polycyclic aromatic carbon compounds.
Eating an extra 50 grams of processed meat (about one hot dog) per day increases the risk of colorectal cancer by about 18%, and eating an extra 100 grams of red meat increases the risk of colorectal cancer by 17%.
The World Health Organization International Cancer Research Center listed it as a primary carcinogen in 2015 and should be avoided.
Red meat is also considered to “possibly” increase the risk of colorectal cancer, and is currently listed as a secondary carcinogen, because the blood matrix iron in red meat can increase the toxicity of nitrogen-nitro compounds. You can still continue to eat it, just avoid high-temperature cooking and excessive intake.
3. Insufficient intake of dietary fiber
Insufficient dietary fiber intake is prone to insulin resistance and increases the risk of colorectal cancer.
The carcinogens in cigarettes will circulate through the blood to the large intestine to cause cancer, and will also increase the occurrence of large intestinal polyps. Long-term smoking or intermittent smoking will increase the risk of colorectal cancer, and two packs a day will increase the mortality rate by 40%.
5. Drink alcohol
Alcohol can affect the metabolism of folic acid, vitamins A and B, and acetaldehyde, the metabolite of alcohol, is also toxic to the cells of the large intestine.Drinking more than three drinks a day increases the risk of death by 1.4 times
People with diabetes who have long-term insulin resistance (rising insulin) have a 30% increased risk of developing cancer.
7. Inflammatory colitis
Inflammatory colitis refers to Crohn’s disease and ulcerative colitis. Long-term inflammation of the large intestine, altered immunity, and an imbalance of gut bacteria increase the risk of cancer.
8. Lack of exercise
Being active in daily life can reduce the risk of colorectal cancer by 24%, because weight loss and fat loss can reduce insulin concentrations and inflammation. Studies have pointed out that if you sit and watch TV for more than 14 hours a week, you will increase the risk of colorectal cancer.
Drinking pearl milk tea late at night can easily cause colorectal cancer?
People who drink pearl milk tea, stay up late, and go to night shifts also have a higher risk of colorectal cancer? According to Dr. Qian Zhenghong, the following seven factors may also increase the risk of colorectal cancer:
1. Sugary foods and drinks
Eating more sweets will increase the incidence of colorectal adenomas, especially rectal line tumors. High blood sugar will also accelerate chronic inflammation, increase inflammatory factors, and induce colorectal cancer.
2. Receive antibiotic treatment
Commonly used antibiotics can change the intestinal flora, and the risk increases by about 8% when used for 15 to 30 days; the risk increases by using antibiotics for 30 days or more
3. Proliferation of pathogenic bacteria
Periodontal disease, Fusobacterium congruentum, human papillomavirus, and pylori infection have all been shown to be related to the occurrence of colorectal cancer.
4. Night shift
Regular night work and lack of sunlight will change the concentration of melatonin in the body. This hormone will change due to light. Some studies have pointed out that working night shifts will increase the risk of colorectal cancer.
5. Receive cancer treatment
Early radiation therapy was not as precise as it is now, and it may irradiate the rectum and cause normal cell lesions.
Patients who underwent cholecystectomy had a slightly increased risk of right-sided colorectal cancer, with a 1.16-fold greater risk
7. Endometrial cancer
Women with endometrial cancer before the age of 50 have a 4-5 times higher chance of developing colorectal cancer.
