In recent years, the incidence of colorectal cancer has been increasing year by year. Data show that one person dies of colorectal cancer every five minutes in China, and most of them are found in the middle and late stages. What is more frightening is that the trend of colorectal cancer in China is particularly young. The average age of onset of colorectal cancer in Americans is 69.8 years old, but in China it is actually 48.3 years old, 20 years younger, and many of them are middle-aged people in their 30s and 40s. Looking at these figures, have you ever worried about yourself and your family? How to prevent colorectal cancer?
Three major early symptoms of colorectal cancer
1.Blood in stool
In fact, 80% of rectal cancer will have blood in stool, and serious cases will have sticky blood stool, but it is easy to be ignored by patients because of its prevalence.
2.Black stool
In recent years, influenced by the trend of detoxification, many people abuse laxatives, which led to a significant increase in colon black stool disease, the disease with adenomatous polyps and colorectal cancer rate of up to 22% -55%.
3.Diarrhea
Continuous change in stool habit, including prolonged constipation, diarrhea or alternating between the two, as well as a significant increase in the number of stools, are some of the symptoms of rectal cancer.
If colorectal cancer is detected early, 90% of it can be cured. However, up to now, only about 20% of patients can achieve early detection. Experts say that these early symptoms of colorectal cancer are very similar to hemorrhoids, so many people will not realize it, and by the time it is found, most patients have already reached the middle and late stage, which is an important reason for the high mortality rate of colorectal cancer.
Six types of high-risk groups of colorectal cancer
1.Patients over 40 years old with gastrointestinal symptoms, such as blood in stool, mucus stool and abdominal pain.
2.People who have a history of colorectal cancer.
3. Immediate family members with a family history of colorectal cancer.
4.People who have a history of pelvic radiotherapy.
5.Direct relatives with family history of colorectal polyps.
6.Patients with precancerous colorectal lesions, such as colorectal adenoma, ulcerative colitis, Crohn’s disease and schistosomiasis.
For these six high-risk groups, experts suggest that from the age of 40, every 3 to 5 years, it is essential to have a colorectal cancer screening. For those with family history, it is recommended to visit a regular oncology center. For non-high-risk groups, it is recommended to undergo colorectal cancer screening every 5 to 10 years from the age of 50.
Six vices are most likely to lead to colorectal cancer
1.Love meatlessness
Love of meat is an important risk factor for the occurrence of colorectal cancer. Studies show that the higher the chance of colorectal cancer in areas where beef is sold well, the higher the chance of colorectal cancer. In addition, excessive intake of saturated fatty acids and animal oils can also lead to the development of colorectal cancer.
2.Heavy taste
Wuhan people have a high incidence of colorectal cancer, and bad eating habits are the cause. Preferring hemp, spicy, sour, salty, fried, fried, smoked, baked eight heavy tastes, the habit of spending the night, as the gastrointestinal tract in the rest time “overtime”, heavy stimulation increases the burden of the gastrointestinal tract, increasing the risk of colorectal cancer.
3.Love to eat pickled food
People in Chaoshan area of Guangdong love to eat pickled food, so it is also a high incidence area of colorectal cancer.
4.Sitting all day
Many people sit in front of the desk for more than ten hours, and the lack of exercise causes the intestinal peristalsis to be weakened and slowed down, and the harmful components in feces are retained in the colon and stimulate the intestinal mucosa. Moreover, in recent years, the trend of colorectal cancer patients is younger, and the number of colorectal cancer patients in urban areas is more than that in rural areas.
5.Eating fast food for a long time
Young workers eat fast food for a long time, and their diet is too single, high in calories and lack of fiber, which increases the risk of colon cancer.
6.Drinking and smoking
These two need not be mentioned, almost all cancer triggers have their figures. It is believed that smoking can produce long-term and continuous chronic stimulation of the colon, thus inducing colorectal cancer.
To prevent colorectal cancer, these diets should be noted
1. Reduce the intake of fatty foods (including animal oil and vegetable oil), as well as fish, poultry, lean meat and low-fat dairy products instead of meat with excessive animal oil, and boiled and steamed food instead of fried food.
2.Increase the intake of green leafy and root vegetables and fruits.
3.Eat more starchy and fibrous foods.
4.Maintain proper weight.
5.The daily salt intake is less than 5 grams.
