In recent years, with the changes in our living and eating habits, food safety, etc., the incidence and mortality of cancer have gradually increased, and people are getting younger; Cancer is one of the tumors with the fastest increasing incidence and mortality in recent years, according to relevant data published by the World Health Organization. In 2020, nearly one million people will die from bowel cancer, and the annual incidence of bowel cancer is still rising. Current epidemiological data show that bowel cancer has risen to the third most common cancer in the world. One, once bowel cancer is discovered, it is already in an advanced stage. Why is bowel cancer in an advanced stage once it is diagnosed?
What causes bowel cancer?
genetic factors
data show that, About 25% of bowel cancer patients have an abnormal family history. If the previous generation has a relative with bowel cancer, the probability of bowel cancer in the next generation is up to 8 times higher than that of normal people.
Obesity Factors
Because of excessive obesity due to uncontrolled diet, sedentary life will also affect colon peristalsis, especially abdominal obesity, which is one of the factors that easily lead to colorectal cancer.
anorectal disorders
p>
For patients with chronic intestinal diseases, such as intestinal polyps, ulcerative colitis and other common anorectal problems, it is also a cancer Pre-disease, the incidence rate is dozens of times that of ordinary people.
Bad eating habits
Long-term poor living and eating habits are also one of the important factors that induce bowel cancer, especially smoking and drinking. Smoking is a long-term persistent chronic stimulus to the large intestine, which basically takes 40 years to develop, and alcohol It will dilate the blood vessels of our digestive tract, thereby destroying the barrier of the mucosal surface of the digestive tract, thereby making it easier for the intestine to promote the absorption of carcinogens.
The main symptoms before the advent of bowel cancer
clinical research statistics, The overall survival rate of colorectal cancer in my country in the past five years is about 65%, and there is a big difference between the early and late survival rates. The survival rate of patients with early colorectal cancer can reach 90%, but the survival rate of patients with advanced colorectal cancer is only 90%. 14%, so early detection of early bowel cancer symptoms plays a crucial role in our treatment and prolonging the life cycle, so when our body has the following symptoms, we must seek medical examination as soon as possible.
abnormal bowel movements, heavy stools, gas, blood in stool, constipation
When the intestinal tract is affected by tumors, the digestive function will also be affected, and the food stays in the intestinal tract for a long time. When it becomes longer and reacts with the flora, more gas will be produced, the number of farts will increase, and the smell will be unpleasant. If you find that the fart has a fishy odor, you should pay attention.
There is also blood in the stool, because hemorrhoids can also cause blood in the stool, so many people will ignore this problem, but the problem caused by hemorrhoids There is a certain difference between blood in the stool and blood in the stool caused by colon cancer. Pay attention to distinguish, the blood in the stool caused by hemorrhoids is bright red, and the color caused by colon cancer is generally dark red, and it is mixed in the stool. There is mucus.
Changes in bowel habits
< span>This is also a common symptom of bowel cancer. With the growth of intestinal tumors, defecation will be hindered to a certain extent and cannot be excreted in time, so it is easy to be confused with constipation, and it is easy to delay the discovery and treatment of the disease.
Pain in abdomen and anus
The tumor and the surrounding tissue will stick together to form a mass. The mass will be different according to the location of the tumor, and the mass will move. There will be obvious pain, and when it appears at the end of the intestine, there will be a pain in the anus.
If you find yourself with the above symptoms, you should seek medical attention for intestinal problems
How to prevent bowel cancer scientifically
In the past decade, the physical activity of men, women and children in our country has increased significantly. Reduced, coupled with changes in diet, eating less and less food, too much animal food and fat intake, eating more, and moving less, so the overweight and obese people in our country are constantly on the rise. increase, which is also one of the risk factors.
Prevention to do “more than two”
Exercise more, bowel cancer is getting younger and younger in recent years, nothing more than because young people are busy with work, eating irregularly, and disrupting their digestive circadian rhythms. People who exercise regularly have a lower risk of developing bowel cancer, even if they also have risk factors for obesity and smoking.
Increase dietary fiber intake strong>, scientists from western countries have shown that eating more fiber-rich foods will greatly reduce the incidence of bowel cancer, and more and more modern junk food has led to people who do not like to eat or even eat fiber-rich foods This makes the incidence of bowel cancer show an obvious upward trend. Eat three meals a day on time, reduce high-calorie food intake, add more water to promote defecation, reduce intestinal overnutrition, and increase metabolism.
