Repeated reminder: When the three symptoms continue to appear, it may be rectal cancer, so be vigilant

j. Ms. Liu and Mr. Wang are a couple. They usually eat with heavy taste. Pickled foods such as various cured meat and salted fish are commonplace. They are reluctant to throw away the leftovers—the leftovers from the day before yesterday. , and eat it hot the next day.

A year ago, Ms. Liu began to have symptoms such as constipation and thin stools. Later, she developed abdominal pain and bloating. It was really unbearable, so she rushed to the hospital for examination, and it turned out to be colon cancer. Fortunately, it was discovered early, and it was fine to remove it under endoscopy.

After the doctor's consultation, he suggested that Mr. Wang also undergo a colonoscopy, but he was also diagnosed with colon cancer. Although his condition was more serious than his wife's, the operation went well.

1. Intestinal cancer: "Rich disease" from eating

According to data from the International Agency for Research on Cancer, more than 1.93 million people will be diagnosed with bowel cancer worldwide in 2020, and China will account for one-third, and the number of diagnoses is still on the rise.

But in fact, as early as a few decades ago, the incidence of bowel cancer was not so exaggerated.

According to Wang Bangmao, director of the Digestive Center of the General Hospital of Tianjin Medical University, the per capita incidence of bowel cancer was only a dozen per 100,000 twenty or thirty years ago, but in 2019, the data shows that the incidence of bowel cancer has reached 38/100,000 second only to lung cancer .

The "culprit" of all this is inseparable from changes in dietary habits, especially high-protein, high-fat diets, and bowel cancer is also known as "the disease of riches and wealth that comes from eating."

A study by the Massachusetts Institute of Technology found that a high-fat diet stimulates the production of many intestinal stem cells, which differentiate into non-functioning cells and form tumors in the intestinal wall.

In addition, a German study found that a high-fat, high-protein diet can lead to changes in the intestinal flora and increase the risk of colorectal cancer. On the one hand, stem cells proliferate in large quantities, and on the other hand, the intestinal flora is disordered. It is the combination of the two that leads to the occurrence of colon cancer.

Nowadays, some people's bad eating habits are constantly "promoting" bowel cancer, such as eating too finely, too high fat, high protein diet, too much pickled food intake, etc., all increase the incidence of bowel cancer risks of.

And some people's habit of drinking alcohol will also promote the protein denaturation of the mucosal surface of the digestive tract, which increases the risk of colon cancer.

2. Rectal cancer and hemorrhoids are stupidly confused?

Professor Wang Xishan, Director of Colorectal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences, said that clinically, 70%-80% of colorectal cancer patients are misdiagnosed as hemorrhoids . Why is colorectal cancer misdiagnosed as hemorrhoids? How to distinguish these two different diseases?

Colon cancer is easily misdiagnosed as hemorrhoids, mainly because these two diseases are very common, and the location of the incidence is also close, and the early symptoms are relatively similar, which is easy to be confused. In addition, many patients think they are hemorrhoids, and go to the hospital to directly say that they have hemorrhoids. The doctor does not carefully identify them and treats them as hemorrhoids.

What is the difference between hemorrhoids and colon cancer? There are three main differences between hemorrhoids and colon cancer:

First, the defecation habits are different

Colon cancer patients will have symptoms such as difficulty in defecation, thin stools, abdominal distension, abdominal pain, and generally do not relieve themselves; while hemorrhoids generally do not cause difficulty in defecation, thin stools, and symptoms of defecation pain will return to normal as the inflammation subsides ;

Second, the symptoms of blood in the stool are different

Colorectal cancer shows blood in the stool, usually there is blood on the surface of the stool, and hemorrhoids are dripping blood after the stool; hemorrhoids generally have bloodstains when defecation is difficult, but colorectal cancer does not necessarily have bloodstains every time ;

Third, the defecation experience is different

Hemorrhoids will have symptoms such as anal falling pain, anal itching, and perianal bleeding; while colorectal cancer will cause abdominal distension, abdominal pain, and alternate symptoms of diarrhea and constipation due to intestinal obstruction .

When the real colon cancer comes, the following symptoms may appear repeatedly, everyone must be vigilant!

1. Deformation of stool

After there is a tumor in the intestinal tract, the stool will be squeezed, causing the stool to become thinner and flatter. If the stool is suddenly deformed, it is necessary to be alert to the occurrence of intestinal cancer.

2. Bloody stool

Most of the blood in the stool caused by colorectal cancer is dark red, accompanied by mucus, and the blood in the stool is not much, so pay attention to distinguish it from hemorrhoids.

3. Changes in bowel habits

A sudden change in bowel habits, alternating diarrhea and constipation, or a sudden increase in the number of bowel movements, frequent constipation, etc., may be caused by intestinal tumors blocking the intestines.

If it is not clear whether it is colon cancer or hemorrhoids, it is best to perform a digital rectal examination and colonoscopy as soon as possible. Digital anal examination can detect nearly half of rectal cancer patients, and colonoscopy can more accurately diagnose various abnormalities in the intestine, and is also the gold standard for colon cancer examination.

3. 5 types of people are high-risk groups of bowel cancer, so you must know

In fact, when the body has obvious symptoms, it is often advanced bowel cancer. Therefore, for high-risk groups, even if the body does not have relevant symptoms, they should be screened regularly.

People with family history of bowel cancer, familial polyposis in immediate family, people with precancerous diseases of bowel cancer such as colorectal adenoma, people with unhealthy living habits for a long time, or people with symptoms related to bowel cancer, all belong to the group People at high risk of colon cancer must be screened as soon as possible and have regular physical examinations.

At the same time, daily develop the following X lifestyle habits, which can effectively prevent the occurrence of colon cancer!

1. Reduce sedentary time

Sitting for a long time will increase the risk of obesity, deep vein thrombosis and other diseases, and it is also related to various cancers such as bowel cancer. Avoid sedentary time.

2. Quit smoking and limit alcohol

Smoking and drinking are related to a variety of cancers such as bowel cancer. It is recommended to quit smoking and limit alcohol as soon as possible.

3. Weight control

Researchers at Chung-Ang University in South Korea analyzed 3,000 people over the age of 40 and found that people with a body mass index over 25 had a higher chance of developing intestinal polyps, which are a major cause of bowel cancer.

4. Eat a healthy diet

In terms of diet, we must pay attention to a balanced and comprehensive diet, try to eat more whole grains, fish and cruciferous vegetables, etc., and eat less red meat, processed meat, and pickled foods.

Some symptoms of bowel cancer are similar to hemorrhoids and are often misdiagnosed as hemorrhoids, but there are many differences between the two.

If you want to prevent bowel cancer, you need to develop good living and eating habits, avoid sedentary, and conduct regular cancer screenings.
