Ms. Liu and Mr. Wang are a couple. They usually eat heavy tastes. Various marinated meats, salted fish and other pickled foods are common. They are reluctant to throw away leftovers - they eat leftovers the day before yesterday, and continue eating them the next day.
A year ago, Ms. Liu began to experience symptoms such as constipation and thinning of stools. Later, she developed abdominal pain and bloating. It was really unbearable, so she rushed to the hospital for examination. After the examination, it turned out to be intestinal cancer. Fortunately, it was discovered early, so it was cured by the endoscopic removal. After the doctor's consultation, he suggested that Mr. Wang also undergo an colonoscopy for . Unexpectedly, he was diagnosed with bowel cancer. Although his condition was more serious than his wife's, the operation was very smooth.
1. Intestinal cancer: "rich disease" that you eat
According to data from the International Cancer Research Institute, in 2020, more than 1.93 million people were diagnosed with intestinal cancer worldwide, accounting for one-third of the proportion in my country, and the number of confirmed cases is still on the rise.
But in fact, the incidence of bowel cancer was not so exaggerated decades ago.
According to Wang Bangmao, director of the Digestive Center of Tianjin Medical University General Hospital, the per capita incidence rate of intestinal cancer was only about 100,000 twenty or thirty years ago, and by 2019, the data on showed that the incidence rate of intestinal cancer had reached 38/100,000, second only to lung cancer .
The "culprit" of all this cannot be separated from changes in dietary habits, especially high-protein and high-fat diets, and intestinal cancer is also called "a disease of wealth caused by eating".
A study from the Massachusetts Institute of Technology found that a high-fat diet stimulates the production of many intestinal stem cells, differentiates into some non-functional cells, and forms tumors in the intestinal wall.
In addition, a German study found that a high-fat and high-protein diet will cause changes in the intestinal flora of , , increasing the risk of colorectal cancer. On the one hand, stem cells proliferate in large quantities, and on the other hand, intestinal flora is disordered. It is precisely because the two are connected inside and outside that lead to the occurrence of intestinal cancer.
Nowadays, some bad eating habits in people are constantly "promoting" intestinal cancer. For example, eating too fine food, too high fat, high protein diet, and excessive intake of pickled foods have increased the risk of intestinal cancer.
. Some people's habit of drinking will also cause protein on the surface of the digestive tract mucosa to denaturate , increasing the risk of intestinal cancer.
2. Can’t tell the difference between rectal cancer and hemorrhoids?
Professor Wang Xishan, Director of the Department of Colorectal Surgery at the Cancer Hospital of the Chinese Academy of Medical Sciences, said that in , 70%-80% of patients with bowel cancer have been misdiagnosed as hemorrhoids . Why is bowel cancer misdiagnosed as hemorrhoids? How to identify these two different diseases?
Intestinal cancer is easily misdiagnosed as hemorrhoids, mainly because both diseases are very common, and the onset is close, and the early symptoms are similar, which is easy to be confused. In addition, many patients think they have hemorrhoids and go to the hospital to see a doctor directly says that they have hemorrhoids. The doctor does not carefully identify them and treats them as hemorrhoids.
What is the difference between hemorrhoids and bowel cancer? There are three main differences between hemorrhoids and intestinal cancer:
First, the bowel cancer habits are different
Patients with bowel cancer will have symptoms such as difficulty in defecation, thinning stool, abdominal distension, abdominal pain, etc., and generally will not relieve it on their own; hemorrhoids generally do not cause difficulty in defecation and thinning stool, Defecation pain symptoms will also return to normal as the inflammation subsides ;
Second, the symptoms of bloody stool
Second, the symptoms of blood stool
Intestinal cancer manifests as bloody stool, which is usually bloody on the surface of the stool, while hemorrhoids are bleeding after the stool; hemorrhoids generally have bloody stains when they are difficult to defecate, Intestinal cancer may not always have bloody stool ;
Third, the feeling of defecation is different
Hemorrhoids will have symptoms such as anal pain, anal itching, perianal bleeding; while intestinal cancer will have symptoms of abdominal distension and abdominal pain due to intestinal obstruction, may also have symptoms of diarrhea and constipation alternating symptoms .
When real intestinal cancer comes, the following symptoms may occur repeatedly. Everyone must be vigilant!
. Poop deformed
After a tumor in the intestine is squeezed, the poop will become thinner and flattened. If the poop suddenly deforms, beware of intestinal cancer.
. Bloody stool
blood stool caused by intestinal cancer is mostly dark red, accompanied by mucus, and the amount of blood in the stool is not much. Pay attention to distinguish it from hemorrhoids.
. Change of bowel movement habits
. Defecation habits suddenly change, diarrhea and constipation alternately, or sudden increase in bowel movements, frequent constipation, etc., which may be caused by intestinal tumors blocking the intestine.
If you can’t tell whether it is intestinal cancer or hemorrhoids, it is best to perform anal fingerprint and colonoscopy as soon as possible. Anal fingerprints can detect nearly half of patients with rectal cancer, and colonoscopy can more accurately diagnose various abnormalities in the intestines, which is also the gold standard for intestinal cancer examination.
Type 5 people are high-risk people for intestinal cancer. You should have a clear idea in your mind
In fact, when the body has obvious symptoms, it is often already has advanced intestinal cancer. Therefore, for high-risk people, even if the body does not have relevant symptoms, they should be screened regularly.
People with a family history of intestinal cancer and familial polyposis among direct relatives, as well as people with pre-cancer diseases such as colorectal adenoma, people with unhealthy long-term living habits, or people with symptoms related to intestinal cancer, are all high-risk groups for intestinal cancer. They must be checked as soon as possible and have regular physical examinations.
At the same time, develop the following X living habits in daily life, which can effectively prevent the occurrence of intestinal cancer!
. Reduce long-term sitting
Sitting for a long time will increase the risk of diseases such as obesity and deep venous thrombosis, and is also related to various cancers such as intestinal cancer. You should avoid long-term sitting.
, quit smoking and limit alcohol
Smoking and drinking are related to various cancers such as intestinal cancer. It is recommended to quit smoking and limit alcohol as soon as possible.
, weight control
Researchers from the Central University of Korea , through a survey and analysis of 3,000 people over 40 years old, found that people with a body mass index of more than 25 have a higher chance of suffering from intestinal polyps, and intestinal polyps are a major cause of intestinal cancer.
, healthy diet
Diet must pay attention to balanced and comprehensive nutrition, try to eat more coarse grains, fish, and vegetables from cruciferous , etc., and eat less red meat, processed meat, pickled foods, etc.
Some symptoms of intestinal cancer are similar to hemorrhoids and are often misdiagnosed as hemorrhoids, but in fact there are still many differences between the two.
If you want to prevent intestinal cancer, you should develop good living and eating habits in normal times, avoid sitting for a long time, and undergo regular anti-cancer screening.
