Constituent cancer refers to malignant neoplasms occurring in the colon and rectal, also known as cortal cancer, mainly in the digestive tracts, where the main symptoms are blood, defecation, abdominal pain and so on. According to the latest data, the incidence and mortality of colon cancer is on the rise, so that we should actively focus on the causes associated with colon cancer and take early active intervention to avoid its occurrence.
I. Causes of colon cancer
The complex causes of colon cancer are the result of a combination of factors, which are summarized below: 1. Dietary factors
High fat, high protein diets: chronic ingestion of high fat, high protein and low-fibre foods may increase the risk of rectal cancer. High proteins and high fat foods increase the amount of methyl cholesterol in excreta, thus increasing the cholesterol distribution, both of which are highly carcinogenic.
Lack of cellulose: Inadequate cellulose ingestion reduces the rate at which faeces pass through the gastrointestinal system, increases the exposure time of carcinogenic substances and gastrointestinal mucous membranes, thereby increasing the risk of rectal cancer.
Vitamins and micronutrients are lacking: chronic deficiencies in vitamins and micronutrients in diet can also increase the risk of rectal cancer. Genetic factors
Genetic factors play an important role in the incidence of rectal cancer. There is a relatively high risk of rectal cancer in the family, especially in the immediate family. This may be related to genetic mutations or genetic susceptibility. Common genetic factors associated with rectal cancer are family non-salent carcinogenic colon cancer, family adenomas, etc. 3. Diseases of digestive tracts
Chronic intestinal inflammation: Chronic intestinal inflammation such as ulcer coliitis and Cron disease, with long-term inflammation leading to intestinal mucous cell malformation and increasing the incidence of rectal cancer.
Adenoma cancer: tumour carcinogenic, adenoma can distinguish three types of adenoma, velvet adenoma and mixed adenoma. Intestines, especially adenomas, are considered to be pre-cancer changes from rectal cancer. 4. Poor lifestyle
Low activity: Undesired lifestyles such as prolonged sit-ins and lack of exercise may slow down intestinal creeps and increase the risk of rectal cancer.
Tobacco use and alcohol abuse: Bad habits such as long-term smoking and alcohol abuse may also play a role in the development of rectal cancer. Other factors
Chemical carcinogen: Long-term exposure to chemical carcinogens such as nitrazine and its compounds may increase the risk of rectal cancer. The incidence of rectal cancer in some of the patients is related to the frequent eating of roasted foods and fried foods.
Obesity: The risk of rectal cancer among the obese population is also relatively high.
Stress is high: long-term stress may also have an impact on the incidence of rectal cancer.
Nutritional guidance for the prevention of colon cancer 1. Increased intake of dietary fibres
Dietary fibres help to stimulate gastrointestinal worming and increase the number of defecations, thus helping to remove carcinogens and toxic substances from the body. Therefore, it is proposed to add to the daily diet foods rich in fibres, such as celery, cabbage, radish, bitter melons, fresh vegetables such as ravioli, corn and whole grain food. Reduced fat intake
The fat in the edible oil does not itself cause cancer, but it promotes the gestation of the cholesterol, while a large amount of the cholesterol produces acne acid in the intestinal bacteria, which has some carcinogenic effect. Therefore, the consumption of grease should be reduced and it is recommended that the daily intake of grease be within 50 grams. At the same time, every effort is made to avoid the consumption of greasy foods such as fried and fried. 3. Food freshness and hygiene
Reduced intake of pickled foods: pickled foods contain carcinogenic substances such as nitrite, and long-term consumption may increase the incidence of rectal cancer. Therefore, pickled foods such as pickles should be minimized.
Avoiding moldy foods: fungus toxins in moldy foods may also pose a threat to intestinal health and should be avoided. 4. Ensuring dietary diversity and nutritional balance
Ingestion of high-quality proteins: Adequate intake of high-quality protein-rich meat, such as milk, chicken chest, fish, etc., to increase their immunity and resistance to tumor cells. However, care should be taken to ensure adequate cooking of meat and to avoid indigestion.
More vitamin-rich vegetables and fruits: To ensure vitamins, minerals and vegetables, such as mussels, mushrooms, tomatoes, apples, peaches, etc., can be selected for vitamin-rich fruits, which not only contribute to the defecation but also provide multiple nutrients for the body. 5. Other recommendations
Prohibition of alcohol: smoking and overdrinking are associated with increased risk of rectal cancer and should therefore be discontinued.
Maintaining healthy weight: Obesity is associated with increased risk of rectal cancer and should therefore be maintained within healthy body weight ranges to avoid obesity.
Periodic medical check-ups: rectal cancer screening can lead to early detection of or pre-cancer pathologies and improve treatment success rates. It is recommended that screening projects such as colonoscopy and faeces submersible blood testing be conducted on a regular basis.
In the light of the above, dietary guidance for the prevention of colon cancer includes, inter alia, increased intake of dietary fibres, reduced intake of oil and pickled food, attention to food freshness and hygiene, ensuring dietary diversity and nutritional balance, and other healthy lifestyles. These measures help to reduce the risk of rectal cancer, but do not fully prevent it. If there are any doubts or symptoms, timely medical consultations should be undertaken.
