Colorectal cancer mainly includes colon cancer and rectal cancer. As a tumor of the digestive system, the disease of the large intestine is closely related to eating habits. Experts analyzed that the younger trend of colorectal cancer is related to the current eating habits of people.
Studies have found that in cities, especially large cities, the incidence of colon cancer is significantly higher than in small towns and rural areas. In cities, the incidence of people with less physical activity is higher than that of people with more physical activity. This is mainly because these people are accustomed to the "two high and one low" diet that is high in fat, high in protein, and low in dietary fiber. In addition, too little exercise can slow down the gastrointestinal motility and easily cause constipation. Long-term constipation will cause toxins to stay in the body for a long time, thereby being absorbed by the body again, and this contains many carcinogens.
The long-term eating habit of eating high-fat foods will increase the secretion of bile acids in the intestinal tract, which will stimulate and damage the intestinal mucosa. If the body is exposed to this kind of stimulation and damage for a long time, it is easy to induce colorectal cancer.
Processed foods such as pickled and smoked are also "frequent customers" on people's tables today. Such foods often contain certain carcinogenic ingredients. Many carcinogens are fat-soluble and will dissolve in fat quickly. The more animal fat you consume from your diet, the greater the risk of dissolving and absorbing carcinogens.
The survival rate of patients with early colorectal cancer after surgery is relatively high. That is to say, if it can be detected, diagnosed and treated early, colorectal cancer is not terrible. But what is worrying is that most patients have unknowingly dragged their condition to the middle and late stages when they saw a doctor.
Generally speaking, colorectal cancer has the following three symptoms in the early stage:
One is blood in the stool. Patients with early rectal cancer are most likely to have blood in the stool, but many people mistake stool bleeding as a symptom of hemorrhoids, which delays the best treatment
Poor eating habits are an important cause of bowel cancer. Once hailed as the first person to be brave, the group has three major investment sectors: aviation, dairy and real estate investment. The chairman of Juneyao Group with total assets of 3.5 billion yuan, Wang Junyao, died in Shanghai due to ineffective treatment of bowel cancer. He was only 38 years old. . The news quickly spread throughout the country. While regretting the death of this young boss due to illness, the high incidence and youthfulness of colorectal cancer has once again become a cruel fact before people.
According to experts, there are currently about 130,000 new cases of colorectal cancer in the country each year. What is disturbing is that statistics from various countries show that the incidence of colorectal cancer, especially colon cancer, is rising rapidly, and young patients have always accounted for a certain proportion. According to the doctor, the incidence of colorectal cancer now accounts for about 12%-15% of all malignant tumors in the whole body. It is a common malignant tumor in China. With the improvement of people's living standards, changes in living conditions and habits, the incidence of colorectal cancer is on the rise. Trends, especially in large and medium-sized cities, the age of onset is mostly around 45 years old.
Poor diet and living habits induce a high incidence of cancer. Regarding Wang Junyao’s situation, the doctor analyzed that the incidence of colorectal cancer has a lot to do with people’s eating habits. As a boss, he must have a lot of social interactions. Long-term consumption of high-fat, high-protein, and low-fiber foods, plus mental stress and stress Large and reduced exercise are high-risk factors leading to cancer. In the etiology of colorectal cancer, diet and environmental factors are more important than genetic and ethnic factors; it is obviously related to the difference in fat content in people's diet. Those whose diet is rich in fiber have a lower incidence of colorectal cancer. In today's society, some young bosses or white-collar workers have unhealthy living habits. They either forget to sleep or eat for work, have a lot of mental stress, and reduce exercise, which directly leads to a high incidence of colorectal cancer among young Chinese.
Colorectal cancer can be self-detected
Some early symptoms of colorectal cancer appear, if you seek medical attention as soon as possible, the cure rate of cancer can be improved.
Fecal occult blood test can be used as a screening method for the early diagnosis of colorectal cancer. Combined with digital anus examination and colonoscopy, colorectal cancer can often be detected early. Experts from the 466 Cancer Hospital said: “We must let everyone know about the early symptoms of colorectal cancer, such as blood in the stool, intermittent blood in the stool, changes in stool habits, frequent stools, abdominal pain, intestinal dysfunction, or unexplained symptoms. If you have anemia, you should see a specialist in time."
High animal fat induces bowel cancer
It is understood that bowel cancer usually refers to colorectal cancer, because the probability of small bowel cancer is extremely low. Colorectal cancer can be divided into two parts: colon cancer and rectal cancer. Judging from the cases of colorectal cancer, obesity is related to the incidence of colorectal cancer. Therefore, the cause of colorectal cancer is closely related to people's eating habits. With the improvement of living standards, people who used to eat more vegetables and grains are now eating a lot of meat and dairy products. Excessive intake of high calories, animal fat and cholesterol, and obvious lack of fiber and vitamins, all increase the incidence of colorectal cancer.
Deep-fried, grilled food and pickled products contain carcinogens, and lack of certain trace elements also increase the incidence of colorectal cancer. A greasy diet can increase the concentration of bile acids and neutral sterols in the colon, change the composition of the coliform flora, and gradually form carcinogens in the intestine. And food additives, meat, fish (such as bacon, ham, salted fish, etc.) treated with nitrite, and some drugs (such as piramidone, chlordiazepoxide, oxytetracycline, etc.) also have carcinogens.
In addition, long-term excessive drinking, smoking, irregular life, mental stress, excessive stress, and too little exercise all directly lead to a high incidence of colorectal cancer in young people. The influence of these factors is greater than the influence of genetic and ethnic factors.
Early detection of symptoms is very important for the treatment of colorectal cancer. Experts reminded that because colorectal cancer is very easy to metastasize, but if you seek medical attention as soon as the early symptoms appear, the cure rate of colorectal cancer can be improved.
The early symptoms of colorectal cancer are not very obvious, but people can still find it early through some daily signs. The first is the change in bowel habits, such as increased bowel movements, more bowel movements, but not many bowel movements each time, or even no feces at all, just discharge some mucus, blood, and the feeling of incomplete defecation; stool strips become thinner and the shape changes , Showing a flat shape, is also worthy of vigilance. The second is the appearance of dull abdominal pain, abdominal masses, intestinal dysfunction, unexplained diarrhea, constipation, etc., or unexplained anemia, weight loss, fatigue, low fever, etc. In addition, if there is blood in the stool or intermittent blood in the stool, you should go to a specialist in time.
