How to prevent rectal cancer in white collars
Although the cause of rectal cancer is not yet fully understood, it is believed that dietary factors, genetic factors, polyps and chronic inflammatory irritation are all closely related to causing rectal cancer to occur. Since rectal cancer is closely related to diet and exercise, we will have a revolution in these two aspects to block the enemy’s attack and turn the danger into success. To remind white-collar workers: rectal cancer is a cunning enemy, which is not easy to be detected. When busy white-collar workers find blood in the stool, they often mistake it for hemorrhoids, which is easy to think about in general, and it is hard to think that it may be rectal cancer or stomach bleeding, etc.
The initial symptom of rectal cancer is blood in the stool. The blood in the stool, however, is a complex clinical symptom that originates from a variety of diseases. If white collar workers find blood in the stool, they should have the following common sense: blood from hemorrhoids is usually bright red, while blood from rectal cancer is usually darker than hemorrhoids; blood from hemorrhoids is often drop by drop, while blood from rectal cancer is sometimes large; although blood from hemorrhoids and rectal cancer is first blood and then stool (while most stomach bleeding is first stool and then blood), rectal cancer is often a mixture of blood and stool. The above are only general cases, and special cases are often more complicated. Anyway, it is easy to seek medical attention in time when you find the symptoms of blood and stool. It is better to do rectal finger examination and barium enema imaging to further confirm the diagnosis.
Because the cause of rectal cancer is not completely clear, there is no special prevention method so far, the following preventive measures are listed below, mainly to reduce the chance of cancer and early detection and early treatment of patients.
1.Actively prevent and treat rectal polyps. Anal fistula anal fissure ulcerative colitis and chronic inflammatory bowel stimulation, multiple polyps papillary polyps once the diagnosis is clear, should be early surgical removal to reduce the chance of cancer.
2, diet should be diversified. Develop good dietary habits, do not be partial or picky, do not consume high-fat and high-protein diet for a long time, and eat fresh vegetables containing vitamins and fiber regularly, which may play an important role in cancer prevention.
3. Prevent constipation. Keep the bowels open.
4. Pay high attention to regular cancer prevention screening. Pay attention to self-examination at any time, improve vigilance and timely diagnosis and treatment after discovering “warning signals”, so as to improve the survival rate of rectal cancer by early detection and early treatment.
Especially for white-collar workers, don’t ignore the changes of your body and don’t neglect to go to the hospital for treatment because you are busy and don’t have time, which is likely to bring more hidden dangers to your body.
How to prevent rectal cancer because the cause of rectal cancer? s etiology is not completely clear, so there is no special prevention method so far. The preventive measures listed below are mainly to reduce the chance of cancer and to detect patients early and treat them early.
(1) Actively prevent and treat rectal polyps, anal fistula, anal fissures, ulcerative colitis and chronic intestinal inflammation; for multiple polyps and papillary polyps, once the diagnosis is clear, they should be surgically removed early to reduce the chance of cancer.
(2) Diet should be diversified, develop good eating habits, do not be partial or picky, do not consume high-fat and high-protein diet for a long time, and eat fresh vegetables containing vitamins and fiber frequently, which may play an important role in cancer prevention.
(3) Prevent constipation and keep the bowel movement smooth.
(4) Pay great attention to regular cancer screening, pay attention to self-examination at all times, improve vigilance, and promptly carry out diagnosis and treatment after discovering “warning signals” to achieve early detection and early treatment in order to improve the survival rate of rectal cancer.
Proper sunlight can help prevent rectal cancer
At present, rectal cancer is the second most common cancer in the list. has jumped to the second place in the cancer list. The occurrence of rectal cancer is mainly related to high-fat and low-fiber diet and inactivity, which is also especially common among white-collar workers. Many white-collar workers do not care about not having bowel movement for one or two days and think it is no big deal. However, when the stool is knotted in the intestine, it becomes more and more dry and difficult, which damages the intestinal wall over time and leads to the accumulation of toxins and cellular lesions, causing rectal cancer.
Early diagnosis of rectal cancer is of great significance. If you find the symptom of bloody stool in daily life, it is easy to seek medical attention in time. It is better to do rectal finger examination and barium enema angiography to further confirm the diagnosis. With early detection, the cure rate of rectal cancer is quite high. Because rectal cancer is an adenoma, early surgery to remove it is usually not a big problem!
How can rectal cancer be prevented? A study in the United States suggests that sunlight is closely related to the incidence of rectal cancer. The incidence of rectal cancer is also low in the southern United States with long sunshine hours. This indicates: vitamin D has a positive effect on the prevention of rectal cancer. The amount of vitamin D in the body of white-collar workers who do not see sunlight in office buildings and go out by car is definitely limited. Since there is a lack of vitamin D synthesized by sunlight, is it effective to take in sufficient amount of vitamin D from the diet?
There is an opinion that vitamin D in the diet works just as well in the body. However, there is another opinion that no matter how much vitamin D is taken in the diet, it is necessary to have the participation of vitamin D from sunlight in order to play its proper biochemical role. Many bedridden elderly people take vitamin D orally to prevent osteoporosis, but studies have shown that vitamin D is not absorbed without the involvement of ultraviolet light and without the stimulation of exercise.
Dietary fiber can fight cancer
The University of Cambridge has published a large study on diet and cancer, with 400,000 people surveyed, the largest ever study on diet and cancer. The results showed that a high-fiber diet was effective in reducing the risk of developing deadly cancers by up to 40%, especially colon and rectal cancers.
In the past, the French medical profession has also found that 30% of cancer cases are directly related to the patient’s diet. The French Academy of Medical Sciences has pointed out in the “Diet and Cancer” survey report that high-fat foods and saturated fatty acid foods such as full-fat milk and meat are not only prone to many types of cancer, especially colon and rectal cancer, but also easy to cause cardiovascular disease.
Dietary fiber can stimulate intestinal peristalsis and shorten the time for food to pass through the intestinal tract, reducing the chance for carcinogenic substances in stool to come into contact with intestinal mucosa and expelling stools and toxins out of the body as soon as possible.
Warm tip: Dietary fiber mainly comes from natural vegetables, fruits, cereals and legumes. Among vegetables, cruciferous vegetables are rich in antioxidant vitamin C and carotene, which can inhibit the synthesis of carcinogenic substances such as nitrosamines, including cauliflower, mustard, cabbage and so on. Most of the yellow and green fruits and vegetables are rich in flavonoids, and other foods such as onions and apple peels also contain flavonoids, which can also help prevent cancer.
Behind hemorrhoids is hidden rectal cancer
Rectal cancer, in its early stages, is easily confused with hemorrhoids, so it is important to distinguish them.
First of all, hemorrhoids often do not cause difficulty in defecation, especially when the stool becomes thin. Even if the nucleus of the hemorrhoid is prolapsed and embedded, it only shows a short-term reluctance to force to relieve stool due to painful defecation; once the edema and inflammation subsides, it immediately returns to normal. In contrast, patients with rectal cancer have difficulty in defecation and thin stool, accompanied by abdominal distension and paroxysmal abdominal pain, and sometimes they can feel bowel sounds. The symptoms usually do not relieve on their own and often worsen progressively.
Secondly, the lump of rectal cancer patients will not shrink, but only grow gradually, cauliflower-like, light red, and easy to bleed when touched: while the lump of hemorrhoid edema is often smooth, dark red or dark purple, and not easy to bleed when touched.
In addition, rectal cancer in late stage may sometimes show corresponding symptoms because the tumor invades the surrounding tissues, such as invasion of bladder may cause painful urination and frequent urination, invasion of presacral nerve will cause severe and continuous pain, metastasis to liver may cause hepatomegaly, jaundice, and anemia, etc.
Therefore, patients with bleeding stools, even with hemorrhoids, should be highly alert to the possibility of rectal cancer and must be further examined to exclude the possibility of cancer. The application of examination methods such as rectal finger examination, proctoscopy or sigmoidoscopy must be emphasized.
Risk group of rectal cancer Colorectal cancer refers to cancerous tumors occurring in the cecum, ascending colon, transverse colon, descending colon, sigmoid colon and rectum, which is one of the most common malignant tumors and ranks third among various malignant tumors. In recent years, the incidence of colorectal cancer in China has been on a significant rise, and the incidence rate in Shanghai alone has increased by 2 to 3 times in 20 years. Especially, it is worth noting that the proportion of young people suffering from colorectal cancer is increasing. Although doctors are convinced that the increase in colorectal cancer is related to the increased fat content in the diet, however, its exact cause is still unclear. Currently, what is known to the medical community is that certain diseases are closely related to colorectal cancer, and people who suffer from these diseases are known as a high-risk group for colorectal cancer. Therefore, it is beneficial to understand these diseases and susceptible groups from the perspective of prevention and early diagnosis.
Colorectal polyp: Polyp is a kind of superfluous organism growing out from the intestinal mucosa, which varies in size, shape, number and location. There are more middle-aged and elderly patients over 40 years old, and polyps are increasing with age, and the disease can be diagnosed by colonoscopy. The origin of polyps is divided into two main categories: adenomatous and hyperplastic (inflammatory). Adenomatous polyps are known to have a higher risk of cancer, especially multiple adenomatous polyps larger than 1 cm in diameter, which are known as precancerous lesions of the colon and must be removed; even patients who have been treated for adenomatous polyps should be reviewed regularly to see if they recur.
Ulcerative colitis: It is not colitis in general, but colitis with recurrent episodes of pus and blood in the stool as the main symptom and “mouth sore”-like ulcers visible on colonoscopy. The chance of cancer in ulcerative colitis is 5 to 10 times higher than in normal people, especially in people who develop the disease when they are underage and whose lesions have been active, extensive and have been in progress for more than 5 years, the risk of cancer is greater. It is worth noting that in recent years, there has been a significant increase in the number of patients with ulcerative colitis in China, and the number of patients with cancer caused by this is also increasing.
Schistosomiasis japonica: The disease is endemic in the southern part of China south of the Yangtze River. The eggs of schistosomes exist in the mucosa of the large intestine for a long time to stimulate the intestinal mucosa and cause cancer. The detection rate of colorectal cancer is 12.3 times higher in areas heavily affected by schistosomiasis compared to areas without this disease.
Those who have received radiation therapy to the pelvis: Patients with uterine and ovarian cancer often have to receive radiotherapy, and their incidence of rectal cancer is 4 times higher than normal, especially after 10 years of radiotherapy and with higher doses of radiotherapy.
Those who have previously suffered from colorectal cancer: about 2% to 11% of colorectal cancer patients have a second primary colorectal cancer lesion (not recurrence) after the first one has been treated, which is called heterochronous multiple occurrence. Therefore, patients should not rest on their laurels just because they have been treated, but should be reviewed regularly. People who have previously undergone surgery for ovarian cancer or breast cancer, or had ureterosigmoid anastomosis are also at high risk of colorectal cancer.
Family members of colorectal cancer patients: The incidence of colorectal cancer is three times higher in those with family history of colorectal cancer than those without family history, which may be related to the same dietary habits in addition to genetic factors.
Others: Patients after cholecystectomy, patients after small bowel anastomosis, workers in asbestos processing industry and textile industry are also high-risk groups.
Dietary principles for rectal cancer patients
The diet of rectal cancer patients should be diversified, not partial and picky, do not consume high-fat and high-protein diet for a long time, and often eat fresh vegetables rich in vitamins and cancer prevention foods. Such as tomatoes, dark green and cruciferous vegetables (celery, guanxi, kale, mustard, radish, etc.), soy products, citrus fruits, malt and cereals, onion, garlic, ginger, yogurt, etc.
Dietary principles for rectal cancer patients
(1) Patients with colon and rectal cancer mostly have recurrent and persistent diarrhea and weak digestive ability, so they should be given food that is easy to digest and absorb.
(2) Patients with colorectal cancer mostly have blood in stool, and advanced patients often have a lot of blood in stool, so they should take less or no stimulating and spicy food.
(3) Patients with prolonged diarrhea or advanced patients with long-term fever, sweating, and damage to fluid, so it is appropriate to drink more water or soup, and the main food can be mainly semi-liquid diet such as porridge and noodles.
(4) Patients mostly have symptoms such as loss of appetite, nausea and even vomiting, so it is appropriate to take a light diet and avoid greasy food.
(5) Patients with advanced colorectal cancer have prolonged diarrhea, blood in stool, fever, loss of nutrients and water, loss of body weight, weight loss, and deficiency of both qi and blood, so it is appropriate to take nutritious tonic juice diet.
Women who smoke are prone to rectal cancer
A new study shows that the risk of developing rectal cancer in women who smoke is nearly twice that of non-smoking women, especially those who smoke heavily every day, smoke for a long time and quit in old age, and have a higher risk of developing rectal cancer. This supports the findings of earlier studies on this topic.
The study, published in the recent issue of the Journal of the National Cancer Institute, said that smoking cessation and prevention remained researchers at The Ohio State University conducted a long-term observational study of 14,000 women, aged 50 to 79 years, on their incidence of rectal cancer. Of these women, 51 percent had never smoked, 42 percent had smoked, and 7 percent were current smokers. The researchers found that of the women who had smoked for an average of 7.8 years or more, 1,242 developed invasive colorectal cancer, including 176 who developed rectal cancer.
Women who were currently smoking had a 95 percent chance of developing rectal cancer, but not an increased probability of colon cancer, compared with those who had never smoked.
These findings held true after the researchers took into account the effects of other factors on the development of colorectal cancer. These factors included, age, race, family history, physical activity, non-steroidal anti-inflammatory drugs, hormone therapy; alcohol consumption, calcium intake, fiber, fat and red meat intake, waist circumference and family history of diabetes in women.
The researchers concluded that the study provides yet another reason to encourage women to prevent smoking and quit. It is a way to prevent the development of rectal cancer, and women who still continue to smoke should receive normal colorectal cancer screenings in a timely manner.
Rectal cancer, eat less smoked food, fried food, too spicy, too stimulating, and not well digested food.
(1) The more animal fat you consume from the diet, the greater the risk of dissolving and absorbing carcinogenic substances.
(2) High-fat diet can increase the secretion of bile acids in the intestine, which is potentially irritating and damaging to the intestinal mucosa. If in such irritation and damage for a long time, it may induce the production of tumor cells and lead to colorectal cancer.
Dietary advice I
(1) Eat less or no food rich in saturated fat and cholesterol. These include: lard, butter, chicken fat, mutton fat, fatty meat, animal offal, fish roe, squid, cuttlefish, egg yolk, as well as palm oil and coconut oil.
(2) Vegetable oils [peanut oil, soybean oil, sesame oil, canola oil, etc.] are limited to about 20-30 grams per person per day [about 2 to 3 tablespoons].
(3) Do not eat or reduce fried foods.
(4) Moderate consumption of foods containing monounsaturated fatty acids, such as olive oil, tuna, etc.
(5) Avoid overheating animal foods and vegetable oils during cooking.
(6) Intake of dietary fiber. The raw power to prevent colorectal cancer increases the intake of dietary fiber, which can reduce the incidence of colorectal cancer. The reason for this may be that dietary cellulose has strong water absorption, which can increase the volume of feces, make feces form, facilitate defecation and reduce the concentration of carcinogenic substances in the intestine, thus reducing the risk of colorectal cancer.
Dietary advice II
(1) Supplement with more than 30 grams of dietary fiber daily.
(2) Eat more foods rich in dietary fiber. For example: konjac, soybean and its products, fresh vegetables and fruits, algae, etc.
(3) Replace fine grains with some coarse grains while maintaining the same amount of staple foods.
(4) intake of vitamins and trace elements. The role of vitamins and trace elements should not be underestimated. Scientific research shows that vitamin A, beta-carotene, vitamin C, vitamin E and trace element selenium have potential roles in the prevention of malignant tumors.
Dietary advice three
(1) Eat more fresh vegetables and fruits to supplement carotene and vitamin C.
(2) Consume walnuts, peanuts, dairy products and seafood in moderate amounts to supplement vitamin E.
(3) Pay attention to the intake of malt, fish, mushrooms and other foods rich in trace elements of selenium.
(4) If, for various reasons, it is difficult to ensure the intake of the above-mentioned foods, you can supplement vitamin and mineral combination in appropriate amounts.
Dietary advice IV
(1) 50g each of horsetail and egg, or kiwi in appropriate amounts. Take 50g day by day and make it into food for year-round consumption. It is an auxiliary treatment for rectal cancer.
(2) 30g of yellow cauliflower, 15g of fungus and 6g of blood residual charcoal. 300ml of juice is obtained from the decoction of the first two species and the blood residual charcoal is taken. Fresh figs can also be taken regularly. It has therapeutic effect on rectal cancer with blood and water in the stool.
(3) rectal cancer and obvious anemia, can be used black fungus 30g, red dates 30, made into food for 1 day amount, eaten day by day.
(4) For those who have reduced white blood cells after radiotherapy or chemotherapy, use coix seeds, gorgonian, rhizome, lotus seeds, etc. to cook porridge with meals and eat them regularly. Or eat more shiitake mushrooms, flat mushrooms, portobello mushrooms, black fungus, silver fungus, etc., can enhance the white blood cells, enhance the body’s immunity.
Dietary advice five
(1) Patients are advised to eat more seed plants, such as mung beans, peas, lentils, adzuki beans, bean sprouts, cereals and potatoes, etc. It is believed that all these seed plants contain compounds that can block the activity of tumor initiation factors.
(2) Nutritionists also found that colored vegetables such as carrots, sweet potatoes, spinach, rape and other foods; can increase the body’s ability to fight cancer, especially carrots are the best among cancer prevention foods. Regular consumption of carrots can reduce the incidence of intestinal cancer. Cabbage and cabbage of kale category contain a substance called indole, which can inhibit the occurrence of cancer. Eating more spinach can clean up heat accumulation in the intestine, reduce the absorption of harmful substances and lower the chance of intestinal cancer. Garlic, scallions and tomatoes have anti-cancer effects; kiwi fruit and barley have certain effects on the prevention and treatment of intestinal cancer, and also have certain anti-cancer effects.
(3) Experts believe that kelp and nori have a large amount of iodine, calcium and carotene, which can transform some toxic organic substances in the body into non-toxic substances, and have the effect of clearing heat, laxative, laxative and intestinal cancer prevention.
