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 the vast majority of them are found in the middle or late stage. What is even more terrible is that the trend of rejuvenation of bowel cancer in China is particularly obvious. The average age of onset of colorectal cancer in America is 69.8 years old, but it is 48.3 years old in China, 20 years younger, and many of them are middle-aged people in their 30s and 40s. Early Three Symptoms of Colorectal Cancer 1.Blood in Stool Many patients think that blood in stool is caused by hemorrhoids and do not pay attention to it, in fact, 80% of rectal cancer will have blood in stool, and serious cases will have mucous blood in stool, which can be easily ignored by patients. 2.Black stool In recent years, under the influence of detoxification trend, many people abuse laxatives, thus triggering a significant rise in black stool disease of colon, in fact, the common explanation is that the colon becomes black, and the rate of this disease accompanied by adenomatous polyp and intestinal cancer can reach 22%-55%. Diarrhea: Continuous change of bowel habit, including sudden constipation, diarrhea or alternating between the two, as well as obvious increase in the frequency of bowel movement, etc. 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 said that these early symptoms of colorectal cancer and hemorrhoids are very similar, so many people will not realize it, and most of the patients have already reached the middle and late stage when it is found, which is also an important reason leading to the high mortality rate of colorectal cancer. Six groups of people have close relationship with colorectal cancer and they are high-risk groups. First, people over 40 years old have digestive symptoms, such as blood in stool, mucus in stool and abdominal pain. Those with a history of colorectal cancer. Immediate family members with family history of colorectal cancer. Fourth, those with a history of pelvic radiotherapy. Fifth, immediate family members with a family history of colorectal polyps. Sixth, those with precancerous lesions of colorectal cancer, such as patients with colorectal adenoma, ulcerative colitis, Crohn’s disease and schistosomiasis. For these six high-risk groups, it is important to undergo colorectal cancer screening every three to five years from the age of 40. Among them with family history, it is recommended to go to a regular oncology center for treatment. For non-high-risk groups, colorectal cancer screening is recommended every 5 to 10 years from the age of 50. Six vices are most likely to lead to colorectal cancer 1, meatless Love of meat is an important risk factor for bowel cancer. Research shows that the area where beef is sold well, the higher the incidence of colorectal cancer. In addition, excessive intake of saturated fatty acid and animal oil can also lead to the development of colorectal cancer. 2, heavy taste Wuhan people have high incidence of colorectal cancer, bad dietary habits are the cause. Favoring hemp, spicy, sour, salty, fried, deep-fried, smoked, grilled eight heavy flavors, used to spending the night, as letting the gastrointestinal tract work overtime for a long time in the rest time, the heavy taste stimulation aggravates the burden of the gastrointestinal tract, and increases the risk of intestinal cancer. 3, love to eat pickled food Eating pickled food is also easy to trigger colorectal cancer, Guangdong Chaoshan region people like to eat pickled food, so it is also a high incidence of colorectal cancer. 4.Sitting for one day Many people sit in front of the desk for more than ten hours, and the lack of movement leads to the weakening and slowing down of intestinal peristalsis, and the harmful ingredients in feces stay in the colon and stimulate the intestinal mucosa. Moreover, in recent years, there is a tendency that patients with colorectal cancer are getting younger, and the number of patients with colorectal cancer in the city is more than that in the countryside. 5, eating fast food for a long time Young office workers eat fast food for a long time, and their diet is too single, high calorie and lack of fiber, which increases the risk of colon cancer. 6, drinking, smoking These two needless to say, almost all the cancer triggers have their figure. Some studies believe that smoking can produce long-term, persistent chronic stimulation of the colon, thus inducing colon cancer. To prevent colorectal cancer, these dietary habits should be paid attention to 1. Reduce the intake of fatty foods (including animal oil and vegetable oil), as well as fish, poultry, lean meat, low-fat dairy products instead of meat with too much animal oil, and boil and steam food instead of fried food; 2. Increase the intake of green leafy and root vegetables and fruits; 3. Eat more starchy and fiber-rich foods; 4. Maintain proper body weight; 5. Daily salt intake Less than 5 grams; 6. Eat more fresh food, less pickled and smoked food, and no moldy food. Less alcoholic beverages.
