Cancer is a disease with a relatively high incidence but a very low cure rate. There are now very many people suffering from cancer. There are many causes of cancer, and unreasonable lifestyle and diet are the main causes of cancer. So who is susceptible to bowel cancer? Let me explain it for everyone!
From the two diseases of hemorrhoids and rectal cancer, hemorrhoids is the most common benign anal disease, and rectal cancer is a malignant tumor with a high incidence of digestive tract. If not diagnosed and treated early, it can be life-threatening. Therefore, experts especially emphasize that stool bleeding should be highly vigilant, not to diagnose hemorrhoids lightly. Even if you have hemorrhoids, you must be alert to the possibility of bowel cancer, which must be further checked and ruled out.
What are the other early symptoms of rectal cancer?
1. Bloating, abdominal pain
The reason is due to intestinal dysfunction or intestinal obstruction. The parts are mostly concentrated in the middle and lower abdomen, mostly dull or swelling pain, and there is a tendency to gradually get worse.
2. Blood in the stool
Because the lesion is close to the anus, the blood color is mostly bright red or dark red, and the blood is often separated from the stool. Only when the amount of bleeding is large, the stool is brown-red and jam-like. This is the case in patients with right colon cancer, and 36.5% of them have visible blood in the stool. This is also the early symptoms of colorectal cancer.
When the long-term chronic blood loss exceeds the compensatory function of the body's hematopoiesis, the patient can develop anemia, an early symptom of colorectal cancer. Tumor obstruction, when the tumor grows to a considerable size or infiltrates the muscular layer of the intestinal wall, it can cause intestinal stenosis, the intestinal lumen becomes smaller, and the passage of intestinal contents is blocked.
4. Changes in stool habits and traits
Patients with rectal cancer may have more bowel movements, but they do not defecate much each time, or even have no feces at all. They only discharge some mucus and blood, and have a feeling of incomplete defecation. When the colorectal tumor is relatively large and has erosions, ulcers or infections, changes in bowel habits, frequency, and constipation or unexplained diarrhea may occur. If the cancer protrudes and grows into the rectal cavity, resulting in a relatively narrow intestinal cavity, the excreted stool is often thin and deformed, and may be flat, and sometimes some bloodshots are attached to the deformed stool.
What kind of people are prone to bowel cancer. Patients who have had colorectal polyps are more likely to have intestinal malignancy; people with severe ulcerative colitis that have not cured for many years need to be alert to intestinal malignancy; have undergone cholecystectomy for 10 years The above-mentioned people need to be alert to intestinal malignant changes; people who regularly consume high-protein and high-fat foods, smoke regularly, and drink alcohol.
Postoperative diet care for bowel cancer should be noted: the diet of patients after bowel cancer surgery should be diversified, not partial, not picky, do not eat a high-fat and high-protein diet for a long time, and often eat fresh vegetables and anti-cancer foods. Spicy and irritating food should not be eaten after bowel cancer surgery, so as not to stimulate wound healing. The diet should be light and less oily, and sesame oil can be used. Patients should eat more foods high in protein and iron, such as animal liver, lean meat, poultry eggs, milk, crucian carp, duck soup, longan, white fungus, soft-shelled turtle, etc., to supplement the patient's varying degrees of blood loss during surgery.
What causes colorectal cancer?
Studies have shown that factors such as diet, environment, genetics, and ethnicity are all related to the incidence of colorectal cancer. The dietary factors and environmental factors are more important. Take Japan as an example. In the 1950s, Japan was the same as China, and it was a country with a lower incidence of colorectal cancer. With the economic recovery and development after the war, the incidence and mortality of colorectal cancer in Japan are also increasing. According to statistics from the Japanese Cancer Society, from 1947 to 1978, the mortality rate of colorectal cancer increased approximately twice, while other cancers such as lung cancer only increased by 60%, gastric cancer and cervical cancer decreased by 30% and 60% respectively.
Analyze the reasons. First, it is caused by an increase in fat diet and a decrease in fiber diet. In recent years, the incidence of colorectal cancer in cities in China has increased, which is also related to changes in diet. Second, the environment is closely related to colorectal cancer. The main environmental factors are: lack of selenium in the soil; the impact of schistosomiasis. In China, the high-risk area of schistosomiasis is also the high-incidence area of colorectal cancer; smoking can easily cause colorectal cancer. The third is genetic factors. About 10% of colorectal cancers are related to genetic factors. Therefore, the offspring of patients diagnosed with familial colorectal polyposis, hereditary non-polyposis colorectal cancer, and sporadic hereditary colorectal cancer should be closely followed up. At the same time, some benign tumors of the large intestine called polyps cannot be ignored. People who suffer from ulcerative colitis for a long time also have a greater chance of getting colorectal cancer.
In summary, people with one of the following conditions should be regarded as high-risk groups of colorectal cancer: adults in high-incidence areas of colorectal cancer, such as large cities in China and the southeast coast; patients with colorectal adenoma, have multiple families Family members of gonadenomatosis; patients who have had colorectal cancer before; patients with schistosomiasis; family members of patients with colorectal cancer; members of cancer family syndrome; people who have received radiation therapy in the pelvis (someone reported that they are susceptible to rectum after 1020 years of pelvic radiotherapy Cancer); patients with chronic ulcerative colitis. Some people believe that the chance of colorectal cancer in people with this disease is 10 times higher than that of normal people.
1. Daily diet should not be too fine
Polished rice white flour, high in sugar, may affect blood sugar and triglyceride levels. These factors can directly or indirectly act on the epithelial cells of the large intestine through various hormones such as insulin to promote canceration and induce colorectal cancer. Therefore, prevent colorectal cancer. Daily diet It should not be too fine.
2. Heavy taste habits are not advisable
People with colorectal cancer who don't like heavy flavors should make corrections if they like pickled meat, fried, and spicy products, because these are important factors that induce colorectal cancer. Therefore, to prevent colorectal cancer, we must pay attention to a balanced diet, eat more fresh fruits, vegetables and other foods rich in vitamins and fiber to promote gastrointestinal peristalsis and prevent colorectal cancer.
3. Abandon greasy eating habits
Excessive consumption of animal fat will increase the burden on the intestines, accumulate fat metabolites to produce carcinogens, induce colorectal cancer, and if there is a lack of carotene, vitamin C, E, D, folic acid and methionine in the diet or lack of minerals, it can also be induced Colorectal cancer. Therefore, we must abandon greasy eating habits to prevent colorectal cancer.
6 tips to cook smartly to prevent bowel cancer
1. Use iron pans and use less non-stick pans or stainless steel pans. Cooking in an iron pot can increase the iron content of food and help prevent bowel cancer. The anti-sticking substance coated on the surface of the non-stick pan can enter the food. Ingestion of this substance in large quantities can cause cancer to the human body. The stainless steel pan contains heavy metals such as iron, chromium, and nickel. Heavy metals will be incorporated into food, among which hexavalent chromium has serious carcinogenic effects.
2. Use less frying, stir-frying and other methods to cook meat directly. You can wrap the raw materials in batter and then fry them. Although cooking methods such as deep-frying and stir-frying can make delicious dishes, there are more carcinogens in fried meatballs, fried fish, and fried steaks. This is because the protein in the meat will produce carcinogens after high temperature. Therefore, people can wrap a layer of batter on the raw materials and then fry them.
3. Vegetables should not be soaked for a long time. They should be washed first and then cut, fried and eaten after they are cut, otherwise the vitamins in the vegetables will be lost.
4. The temperature during cooking should be controlled within 180℃, and no continuous high-temperature frying. If the oil temperature is too high, do not cook for more than 2 minutes. This can effectively reduce carcinogens in food and prevent bowel cancer.
5. Use vinegar when cooking to protect vitamins from being decomposed and prevent bowel cancer.
6. Brush the pot every time you cook a dish. There may be carcinogens in the pot scale left over from the previous dish, so you must clean the pot after each dish.
5 kinds of vegetables that can prevent bowel cancer in life
The chlorophyll in bean sprouts can prevent and treat bowel cancer, especially rectal cancer. The abundant aspartic acid can reduce the accumulation of lactic acid in the body and help eliminate fatigue. Traditional Chinese medicine believes that bean sprouts are sweet and have the effects of clearing away heat, detoxifying, and promoting dampness.
This product contains asparagine, aspartic acid and a variety of steroids, and has certain effects on fatigue, edema, and dysuria. The United States found that this vegetable has the function of preventing the spread of cancer cells, and has special effects on bowel cancer, lymphoid granulation tumors, bladder cancer and kidney stones. The main anti-cancer component is the paraginase in tissue protein, a substance that normalizes cell growth and can effectively control the growth of cancer cells. Asparagus must be cooked before eating. It is best to eat before meals.
Cabbage has the effects of nourishing bone marrow, strengthening joints, strengthening bones, organs and clearing heat and pain. At present, it is known that indole-3-acetaldehyde and flavonoids contained in it can induce 54 times increase in the activity of hydrocarbon hydroxylase in the liver, increase the activity of this enzyme in the small intestine mucosa by 30 times, and reduce gastric cancer and intestinal cancer. Chance of onset.
It has the effects of invigorating the stomach and spleen, promoting body fluid and replenishing qi, and has the effect of laxative and stasis for accumulating chancre. The carotene contained is an anti-cancer nutrient. ,
Lentils have the functions of invigorating the spleen, dehumidifying, relieving heat and detoxification. This product can be used for gastrointestinal tumors with weak spleen and dampness and internal resistance. It can stimulate lymphocytes in the body to transform into tumor-killing cells, and can stimulate the human immune system to improve digestion and absorption.
Conclusion: Many people are afraid of cancer. Therefore, if we want to stay away from the threat of cancer, we must do a good job in preventing cancer. From the above knowledge, we can see that we can prevent cancer through diet or exercise. Hope the above knowledge can help everyone!
