The large intestine, including the colon and rectum, is about 1.2 to 1.5 meters long and is located roughly around your abdomen and connected to the anal canal. The large intestine is a high incidence site for diseases. With the improvement of people’s economic condition and living standard, the incidence of colorectal tumor is also increasing year by year, which should be sufficiently alerted and paid attention to. There are several kinds of people who should pay special attention to the occurrence of colorectal cancer: 1. People who often eat meat and less exercise: research shows that the occurrence of colorectal cancer is obviously related to high fat and high protein diet. People who eat red meat (beef, pork, etc.) for a long time and are too lazy to move should pay the most attention. You should not eat too much even if you eat well. 2.People whose immediate family members have had colorectal cancer: If your parents and siblings have had colorectal cancer, then your risk of colorectal cancer is 3 times higher than the average person. Genetic factors play a role in it. 3.People with original colorectal adenoma, chronic inflammation and other colorectal diseases: most of the colorectal cancer occurs from adenoma of the colon, generally speaking, colorectal adenoma may evolve into colorectal cancer after about 10 years. Daughters-in-law finally boil into mothers-in-law. 4.People with bleeding stools: Hemorrhoids can cause bleeding stools. Many people with hemorrhoids take stool bleeding lightly, knowing that colorectal cancer can be hidden from the world. 5. Middle-aged and elderly people with abdomen normally fine, but suddenly bloating and poor stool flow: the older you are, the higher the risk of colorectal cancer. If your abdomen has not been opened or operated, but you have bloating and difficulty in defecation, you should be alert to colorectal cancer and seek medical attention quickly. The occurrence and growth of colorectal tumor will cause the lumen of large intestine to become narrow, resulting in partial or even complete intestinal obstruction, abdominal distension, difficulty in defecation or even failure to defecate. In short, there is no unexplained “love”, so go to the hospital to investigate the cause. Welcome to consult about colorectal cancer!
