Colorectal cancer is a collective term for rectal and colon cancer, also known as colorectal cancer. According to data, the number of new cases of colorectal cancer in China is increasing at an average rate of 3%-4% each year, which has seriously endangered people's health.
Many people mistakenly believe that colorectal cancer only occurs in the elderly. In fact, it is not. In recent years, the incidence of colorectal cancer among young people has also increased rapidly. We should be soberly aware that "colorectal cancer may occur at any age. This is not old age. Human diseases". Therefore, every age group should not be ignored, so what should we do to face colorectal cancer?
Last week we talked about the predisposing factors of colorectal cancer (do you know all about the predisposing factors of colorectal cancer?). In addition to eating habits and lifestyle, it also includes genetics, polyps and other factors. Therefore, the prevention of colorectal cancer is not only Including the direct prevention of improving diet and living habits, as well as the prevention and treatment of precancerous lesions.
Here are four ways to introduce common sense in preventing colorectal cancer:
Reasonable diet to prevent colorectal cancer
1. Increase high dietary fiber intake
A large-scale survey on diet and cancer conducted by 400,000 people at the University of Cambridge in the United Kingdom showed that a high-fiber diet can effectively reduce the risk of cancer by 40%, especially colon cancer and rectal cancer. High dietary fiber can increase intestinal peristalsis, promote defecation, reduce the damage of waste and toxins to intestinal wall cells, thereby preventing colorectal cancer.
2. Reduce the intake of red meat or processed meat
Processed meat products refer to meat that has been salted, air-dried, fermented, and smoked, such as hot dogs, ham, beef jerky, canned meat, etc.; red meat includes pork, beef, mutton, rabbit, and so on. The study found that people who regularly eat red meat (eating 5 ounces of red meat a day in one study) have a 24% higher risk of colorectal cancer than others.
Scientific medication to prevent colorectal cancer
1. Folic acid
A study in China found that: 1 mg/d folic acid intervention can reduce the occurrence of colorectal adenomas, and found that plasma folic acid levels increased by at least 3 times (9.22/2.49 μg/mL) can effectively prevent the occurrence of colorectal adenomas. Thereby preventing the occurrence of colorectal cancer.
Aspirin-like non-steroidal anti-inflammatory drugs can reduce the occurrence of colorectal adenomatous polyps, thereby reducing the occurrence of colon cancer; in recent years, more and more studies have shown that if aspirin is taken after the diagnosis of colorectal cancer, it can reduce tumor recurrence. Improve survival rate.
3. Vitamin D
Vitamin D deficiency is one of the risk factors for colorectal cancer. In a study published in the journal Gut, researchers found that people with higher blood vitamin D levels have a lower risk of colorectal cancer. Regularly receive sunlight, use high-quality safe sunbeds or take vitamin D3 supplements, you can maintain the vitamin D content in the optimal range of 50-70 nanograms per milliliter.
It is worth reminding that the choice of drugs should be in accordance with the doctor's advice, and do not take drugs blindly.
Good living habits prevent colorectal cancer
1. Reasonable physical exercise
Modern people’s exercise volume decreases and the intestinal peristalsis slows down, which will increase the incidence of colorectal cancer. Regular exercise can reduce the risk of colorectal cancer by 24%. Engaging in 30 minutes of aerobic exercise every day can reduce the conversion of intestinal polyps into colorectal cancer by one third.
2. Control your weight
A large number of studies have shown that being overweight or obese can more than double the probability of developing colorectal cancer. For your health, you must maintain your weight at an ideal target!
3. Avoid long-term smoking and long-term heavy drinking
Smoking and drinking are important risk factors for colorectal cancer. Smoke contains nicotine, which can stimulate the large intestine and cause colorectal cancer. Drinking a lot of alcohol is also easy to irritate the intestines. Therefore, drinking moderately can reduce the risk of colorectal cancer.
4. Develop healthy bowel habits
In daily life, maintaining healthy bowel habits every day can shorten the residence time of carcinogens in the intestine. After each bowel movement, you should also pay attention to whether the color and character of the stool are abnormal. The normal frequency of bowel movements is once a day, the best time to defecate is early in the morning every day, and the duration of bowel movements is about 3 to 5 minutes. If you read cellphones, magazines, etc. during defecation, it will prolong the time of defecation and increase the retention time of blood in the anus, thereby increasing the possibility of hemorrhoids.
Regular screening to prevent colorectal cancer
The high-risk factors for the formation of colorectal cancer are history of intestinal polyps, mucus blood in the stool, and chronic diarrhea. The formation time is relatively long. Therefore, patients with such intestinal diseases should be more vigilant and actively treat intestinal diseases. Microscopy, early detection, prevention and treatment to prevent cancer.
·For those over 50 years old and asymptomatic, it is recommended to have a soft sigmoidoscopy every 5 years and an annual stool occult blood reaction test;
·If there is a middle-risk group with polyps, family history of colorectal cancer, etc., it is recommended to undergo a colonoscopy once every 3 years;
For high-risk groups such as chronic ulcerative colitis, familial colorectal polyps, juvenile polyposis, and hereditary non-polyposis, colonoscopy is recommended for 1 to 2 years.
Finally, I will introduce some daily foods to prevent colorectal cancer:
Garlic is one of the most effective foods for preventing colorectal cancer. It contains a certain amount of volatile oil. The main component of this volatile oil is allicin, a kind of phytoncide. In addition, it also contains minerals such as selenium and sulfur. Strong anti-cancer effect.
2. Chinese cabbage
Don't underestimate Chinese cabbage, it has a strong antipyretic effect. Moreover, the crude cellulose contained in Chinese cabbage can also stimulate gastrointestinal peristalsis, allowing waste and carcinogens in the body to be discharged as soon as possible, helping prevent bowel cancer.
In addition to being rich in protein, complex carbohydrates, and dietary fiber, apples also contain a variety of vitamins and minerals. The cellulose it contains can promote gastrointestinal peristalsis, increase stool volume, and help the recovery of colorectal cancer.
4. Dragon fruit
Pitaya has the effects of lowering cholesterol and moisturizing the intestines. Its fruit and stem juice have an inhibitory effect on tumors and viral infections, so patients with colorectal cancer can often consume dragon fruit.
Bananas are rich in magnesium and potassium. These substances have certain anti-cancer and anti-cancer effects. Patients with colorectal cancer can also eat bananas regularly.
The resveratrol contained in grapes can prevent normal cells from becoming cancerous and inhibit the spread of malignant cells. Traditional Chinese medicine believes that grapes have the functions of invigorating qi and blood, eliminating troubles and quenching thirst, strengthening stomach and diuresis.
