Elderly diet to achieve a combination of thickness
Because there is nothing wrong with it, you can eat and drink, and often exercise. Before the onset, there is no bad feeling, except for a little bloody stool.
However, the results of the doctor’s examination are unquestionable. In the middle and late stage of colon cancer, the doctor said that it is relatively timely, and the surgical resection is not bad. It is hard to say later.
Colon cancer: eating too good digestive tract disease colon cancer is a common digestive tract tumor, with the highest incidence of 40-50 years old, its incidence and death rather than common malignant tumors such as gastric cancer, esophageal cancer, lung cancer, etc., butThe incidence is now getting higher and higher.
Common causes Previously, due to differences in lifestyle and diet between the West and the West, patients decreased, but most had a significant increase.
The cause of colon cancer is not yet clear.
But there are mainly the following factors.
Genetic causes Some diseases such as familial polyposis, colon adenoma, schistosomiasis colitis and ulcerative colitis are closely related to the occurrence of colon cancer.
Dietary factors are high, high meat, low-fiber diet and colon cancer have a certain relationship.
It is generally believed that sorghum recipes and insufficient cellulose are the main causes of the disease.
Studies have shown that a diet of saturated fatty acids increases the concentration of bile acids and neutral steroids in the colon and alters the composition of the coliforms.
Bile acids produce carcinogens through the action of bacteria.
Food fiber, including cellulose, pectin, hemicellulose, lignin, etc., absorbs water, increases the amount of feces, and replaces the concentration of intestinal residues, which can reduce the time that feces pass through the large intestine and reduce the time when carcinogens come into contact with intestinal mucosa.When plasma fiber is insufficient, it is one of the pathogenesis factors of colon cancer.
The incidence of intestinal cancer in chronic intestinal inflammation such as ulcerative colitis is higher than that in the general population. In the development of proliferative mutations of inflammation, polyps are often formed and further developed into intestinal cancer.
According to statistics, in patients with colon polyps, the incidence of colon cancer is five times that of patients without colon polyps.
Familial multiple intestinal polyposis, the incidence of cancer is higher.
Early detection of colon cancer should not be difficult to find the above clues, should go to the hospital as soon as possible.
It mainly includes the following aspects: regular fecal occult blood test for middle-aged and high-risk groups, digital rectal examination and fiberoptic colonoscopy may be an effective method for early rectal cancer and colon cancer.
In particular, alternating constipation and increased frequency of bowel movements accompanied by blood in the stool must be checked as soon as possible.
Some patients refuse to check because of the ease of rectal examination, which often misses a good chance of early detection of colon cancer.
The blood in the stool is checked once a year for people over the age of 50, which can be used as a primary screening method for large-scale colon cancer screening.
Fecal occult blood test can also suggest stomach ulcers, stomach cancer, large intestine polyps and other digestive tract diseases.
Endoscopy includes examinations such as proctoscopy, sigmoidoscopy, and fiberoptic colonoscopy.
Those who are eligible to check from the age of 50 for three consecutive years, once a year.
If it is negative, it will be checked every four years.
Where there is a change in blood in the stool or stool, and no abnormalities are found by digital rectal examination, routine sigmoidoscopy should be performed.
In addition, CT, B-ultrasound, and ultrasound colonoscopy are helpful for the diagnosis and metastasis.
The main alarm signal of constipation and bloody stools is worthy of attention. The early stage of colon cancer is asymptomatic, leading to an increase in the size of the cancer and secondary complications. Only when it is discovered, most of the time has arrived.The middle and late stages of cancer have made it difficult to treat.
Therefore, paying attention to some changes in the body is very helpful in preventing colon cancer.
The main symptoms are: gastrointestinal dysfunction, intestinal obstruction symptoms, bloody stools, abdominal mass, systemic symptoms (may have varying degrees of malnutrition, systemic failure, and dyscrasia, etc.) and anemia and weight loss.
Surgical treatment is the best way. If you want to find the above symptoms, you must first actively treat chronic complications such as colon or rectal polyps, schistosomiasis, bacterial dysentery, amoebic and chronic ulcerative colitis.
Once the diagnosis is clear, in addition to the advanced cases, early surgical treatment should be performed and a phase of eradication should be performed.
It is recommended to eat more vegetables and eat less meat. The current cancer-causing factors are: (1) The incidence of colon cancer is proportional to the amount of food and animal protein consumption, that is, high animal protein, high feces can easily lead to colon cancer.
(2) The incidence of colon cancer is high in economically developed areas, which is mainly related to their alternative structure. Except for high animal protein and high feces, the diet is too fine, such as beef, less cellulose and refined rice noodles, so-called “Western”Cultural diet, prone to colon cancer.
This is mainly because adults in food and their breakdown products may have carcinogenic or synergistic carcinogenic effects.
The dietary supplement of less cellulose reduces the amount of feces, reduces the length of the stool through the interconnection time, and causes the concentration of synergistic carcinogens in the feces to increase, and the time of contact with the colonic mucosa is prolonged. Carcinogenic substances may be cancerous if they are in contact with the colonic mucosa for a long time.
Therefore, colon cancer can be prevented from the following two aspects.
(1) Should pay attention to eating more fruits and vegetables, such as spinach, rape, cabbage, celery, fruit, etc., in order to keep the stool smooth, reduce the contact time of carcinogens in the feces and colonic mucosa.
(2) Reduce the intake of aunts and animal proteins in food.It can reduce the carcinogen production and carcinogenesis of its decomposition products, in order to reduce the potential risk of colon cancer.
Colon cancer high-risk group Men over the age of 40 are high-risk colon cancer patients. If you have a colonoscopy every year, it is best not to give up because of the substitution during the examination, because the characteristics of colon cancer and other cancers are characterized byThe sooner you find the treatment, the better.
The doctor also reminded that patients who do not like to eat vegetables and who have chronic enteritis are at high risk of colon cancer.
