Having intestinal polyps makes you more likely to get colorectal cancer. How to eat to prevent colorectal cancer?

Colorectal cancer mainly includes colon cancer and rectal cancer. There are often no symptoms in the early stage. When non-specific symptoms such as blood in the stool, abdominal pain, and diarrhea appear, the patient is usually in the middle or late stage. The high-risk groups for colorectal cancer mainly include: symptomatic people over 40 years old in areas with high incidence of colorectal cancer; people who have received surgical treatment for colorectal cancer or colorectal polyps; people whose direct relatives have suffered from colorectal cancer or colorectal polyps.

Who is more likely to develop colon cancer?

1. Patients with colorectal polyps: Polyps are mainly divided into two categories: adenomatous and hyperplastic (inflammatory). It is known that adenomatous polyps, especially multiple polyps, are prone to canceration. The incidence of colorectal cancer in patients with adenomatous polyps is 5 times higher than that in patients without adenomas! In particular, large adenomas with a diameter greater than 1 cm are more dangerous. Therefore, adenomatous polyps are called "precancerous lesions of colorectal cancer" and must be removed completely to prevent future problems. Even after removal (including surgical resection), we should still be vigilant against recurrence. Inflammatory polyps have a lower chance of becoming cancerous.

2. Patients with ulcerative colitis: The risk of cancer in patients with ulcerative colitis is 5 to 10 times higher than that in normal people. If the disease occurs before adulthood, the lesions are always active and widespread, and the disease lasts for more than 5 years, the risk of cancer is even greater.

3. Those who have received pelvic radiotherapy: Most of them are patients with ovarian and uterine cancer. Their incidence of rectal cancer is 4 times higher than that of the general population. Rectal cancer usually occurs 10 years after radiotherapy, especially in patients with a large dose of radiotherapy.

4. Those with a family history of colorectal cancer: The incidence of colorectal cancer in those with a family history is three times higher than that in those without a family history, which may be related to the same eating habits.

5. Patients who have undergone cholecystectomy: After cholecystectomy and proximal and distal small intestine anastomosis, the toxic secondary bile acid directly enters the colon and stimulates the intestinal mucosa, increasing the risk of developing colon adenomatous polyps and cancer.

6. Those engaged in certain occupations: such as asbestos processing industry and textile industry workers.

How to eat to prevent colorectal cancer?

Intake of more dietary fiber, preferably more than 30 grams per day, can be achieved by eating more foods rich in dietary fiber, such as konjac, soybeans and their products, fresh vegetables and fruits, algae, etc.; on the premise of maintaining the same amount of staple food, use some coarse grains to replace fine grains. Increasing the intake of dietary fiber can reduce the incidence of colorectal cancer. Dietary fiber has strong water absorption, which can help the formation of feces, facilitate defecation, and reduce the concentration of carcinogens in the intestines, thereby reducing the risk of colorectal cancer. The role of vitamins and trace elements cannot be underestimated. Scientific research shows that vitamin A, vitamin B, vitamin C, vitamin E, trace element selenium, etc. have potential roles in preventing malignant tumors.

Diet to prevent colorectal cancer

1. Choose foods rich in crude fiber

Such as coarse grains, vegetables, fruits, etc. Crude fiber can increase food residues, stimulate the intestinal wall, promote intestinal peristalsis, and make feces easier to discharge.

2. Eat more gas-producing foods

Foods such as beans, yams, potatoes, radishes, onions, bean sprouts, leeks, etc. can stimulate intestinal peristalsis, shorten the time for food to pass through the intestines, and promote defecation.

3. Choose foods that moisturize the intestines and promote bowel movements

Foods such as honey, sesame seeds, walnuts, yogurt, and agar-agar can soften stool and facilitate excretion.

4. Choose foods rich in vitamin B

Foods such as cereals, beans, peanuts, nuts, lean meat, and offal can promote intestinal peristalsis and help defecation.

5. Vegetable oils such as sesame oil, peanut oil, corn oil, rapeseed oil, soybean oil, etc.

It not only has the effect of moisturizing the intestines, but can also break down and produce fatty acids, which can stimulate intestinal peristalsis and facilitate defecation.

6. Drink enough water every day

At least 8-10 cups. Drinking a cup of light salt water or cold boiled water in the morning can stimulate intestinal peristalsis and soften the stool.

7. Avoid strong condiments and beverages

Such as chili, mustard, pepper, strong tea, coffee and other foods.

Patients should go to the hospital in time. Do not underestimate constipation, it can be confusing sometimes. Elderly people at home do not want to trouble their children, so they bear the discomfort by themselves. This phenomenon is very common. Therefore, elderly friends with constipation must go to the hospital in time. If it is not a tumor, it is better. If you have cancer, it is not terrible. For colorectal cancer, early detection and treatment will have a good effect.
