Effective measures to prevent rectal cancer

1。 Don't eat too much salty and spicy food, and don't eat overheated, supercooled, expired or deteriorated food; People who are old and weak or have genetic diseases should eat some anti-cancer foods and alkaline foods with high alkali content to maintain a good mental state.

2。 Have a good attitude to deal with pressure, combine work and rest, and don't be overtired. It can be seen that stress is an important cause of cancer. Traditional Chinese medicine believes that stress leads to overwork and weakness, which leads to the decline of immune function, endocrine disorder and metabolic disorder, leading to the deposition of acidic substances in the body; Stress can also lead to mental stress, causing qi stagnation and blood stasis, toxic fire invagination and so on.

3。 Strengthen physical exercise, strengthen physical fitness, and exercise more in the sun. Hyperhidrosis can excrete acidic substances in the body with sweat and avoid forming acidic physique.

4。 People with regular life and irregular living habits, such as singing karaoke all night and playing mahjong, will aggravate the acidification of the body and get cancer easily. It is necessary to develop good living habits, maintain a weak alkaline constitution, and keep all kinds of cancer diseases away from yourself.

5。 Don't eat contaminated food, such as contaminated water, crops, eggs and moldy food. Eat some green organic food to prevent diseases from entering the mouth.

What food to eat to prevent rectal cancer?

1. Sweet potato: Sweet potato, also known as sweet potato, contains more carotene, lysine, plant fiber and dehydroepiandrosterone, which can prevent rectal cancer.

2. Pumpkin: rich in vitamin A, vitamin C, calcium, cellulose, tryptophan -P, etc. Eating more can prevent obesity, diabetes, hyperlipidemia and high cholesterol, and it is a good food to prevent cancer.

3. Asparagus: contains selenium and plant fiber, which can be used to prevent and treat various cancers.

4. Garlic: Experiments have confirmed that allicin and allicin have a strong inhibitory effect on many cancer cells, and allicin can also block the synthesis of nitrosamines in the body. Garlic is rich in selenium and germanium, which can activate the phagocytosis of macrophages.

5. Green tea: According to extensive research at home and abroad, it is considered that tea, especially green tea, has a very obvious anti-cancer effect. Its main component is catechins, and the antioxidant components of green tea have obvious inhibitory effects on the malignant transformation of cells induced by various carcinogens, including aflatoxin, benzopyrene, cigarette carcinogens, amino acid pyrolysis products and so on. It has been reported in China that drinking 3 grams of green tea twice a day and making tea with 150 ml boiling water can prevent cancer.

6. Radish and carrot: the farmer's proverb "Eat radish in winter and ginger in summer, and you don't have to run a pharmacy all your life". Radish contains a variety of enzymes, which can eliminate the carcinogenic effect of nitrosamines; Its lignin can stimulate the immunity of the body; The spicy taste of radish comes from mustard oil, which can stimulate intestinal peristalsis. Radish contains a lot of vitamin C, and carrot is also rich in carotene. So they have a good anti-cancer effect.

2. Early signs of intestinal cancer

The stool suddenly becomes very thin; Bloody stool; Sudden constipation, diarrhea or unclean feeling; Sudden flatulence, fullness or colic in the abdomen; Not thin, but very thin; Tired, exhausted.

Seeing this, you may also understand that it seems that the symptoms of colorectal cancer are not so special and easy to be ignored. Therefore, for high-risk groups, we should be vigilant and pay more attention to our physical changes.

Who are the high-risk groups?

One is the elderly. More than 90% of colorectal cancer is caused by people over 50 years old.

Second, people with a history of intestinal polyps or colorectal cancer.

Third, people who have had inflammatory bowel disease. For example, people with ulcerative colitis or Crohn's disease.

4. People with two kinds of familial hereditary diseases: one is familial adenomatous polyposis, and the other is hereditary nonpolyposis colorectal cancer.

Fifth, people whose family members have had colorectal cancer or colon polyps.

In addition, some unhealthy lifestyles, such as smoking, drinking and lack of exercise, will increase the risk of colorectal cancer. A high proportion of red meat (pork, beef, mutton, etc. ), too much processed meat (ham sausage, lunch meat, etc. ) or too little dietary fiber is also closely related to the occurrence of colorectal cancer.

Three examinations found colorectal cancer.

In addition to being careful when defecating every day, there are three effective tests to detect colorectal cancer early.

Check the stool first, that is, a high-sensitivity fecal occult blood test. Colorectal cancer is on the intestinal surface, and sometimes a small amount of blood is discharged through stool.

Second, sigmoidoscopy. This is a relatively short fiberscope, which can detect tumors early.

Third, colonoscopy. This mirror is long and can examine the whole large intestine.

It is recommended that people over 50 and under 75 take these three tests.

Specifically: after the age of 50, do a sigmoidoscopy every five years, and it is recommended to do a fecal occult blood test every three years. The latter is convenient and easy to do, and it is best to do it once a year. The most effective colonoscopy is recommended once every 10 years, that is, once every 50 years, 60 years and 70 years.

For the elderly over 75 years old, when cancer is found through these tests, the benefits of reducing the total mortality rate are not obvious, so it is not recommended.

The above is a recommended test for the general population. However, if you have a close relative with colorectal cancer, you should start these screenings 10 years before the age of this relative with colorectal cancer. In order to find it early and treat it in time.
