"Grandpa, grandpa! Your poop today is so weird!" The 53-year-old Li just got up from the toilet, and his 3-year-old grandson rushed in to make trouble for convenience, and curiously rushed. Looked in the toilet, "Okay, don't be naughty, aren't some of them thick and thin." Lao Li glanced at his excrement in the toilet disapprovingly, thinking: Now it is more convenient every day, and it has been more constipated than before. Feels much better! He didn't know that the poop that had changed its appearance and habit was an important signal that the intestines expressed danger to the outside world.
After a short while, Lao Li went from the previous day’s convenience to several times a day, and always felt very anxious every time. When it was really convenient, he was very unhappy. There was some feeling of bulging in his anus. “Is it a bad stomach eating recently? Now?" Lao Li stood up while thinking about it. This time he looked back and was startled. A dark red color appeared around his excrement. "It's not the old problem of hemorrhoids? But it's not like before. It hurts the same." He thought, he should go to the hospital. After going to the hospital for a series of examinations, the doctor secretly told Lao Li's son that Lao Li was likely to have a malignant tumor-colorectal cancer! How could Lao Li, who is always young and energetic, get the scary cancer all at once?
Colorectal cancer is a common malignant tumor of the gastrointestinal tract. Middle-aged and elderly people aged 40-60 with unexplained stool characteristics and defecation habits like Lao Li should pay special attention to it, and because colorectal cancer is a polygenic inheritance Sexual diseases, so two or more of the first-degree relatives (such as parents, brothers and sisters, children) have suffered from colorectal cancer, and the chance of getting it is higher. People who like to eat big fish and meat, high-fat, high-protein, and high-calorie foods on weekdays, and who don’t like to eat vegetables and fruits that are rich in fiber should also be vigilant. So did Lao Li ever have a chance to discover his own problems earlier? As an important excretion system for human beings, the intestine, in addition to absorbing nutrients, is like a sewage pipe, it also helps us excrete unwanted waste outside the body every day, although it is difficult to see the situation in the intestine without the aid of equipment. , But every day's excrement-feces, like a "messenger", conveys to us the health signals of the intestines every day, but we have not paid attention to it.
The most obvious sign of early colorectal cancer is the change in the shape of the stool, such as from thick to thin, or the shape of the stool is irregular, there is a sunken piece, or the front is thick and the back is thin. This is because the cancer grows in the intestine. Occupies a part of the intestinal space, and the digested waste is squeezed and obstructed. When it is discharged, it is impossible to form the original intestinal shape-the healthiest "banana stool". The second is the color of stool. Darkening or dark red is a sign of bleeding in the intestine. The third point to observe is the texture of feces. Feces that are thinned for no reason or accompanied by mucus are also manifestations of the intestinal lining or other tissues being excreted with the feces. This phenomenon will not occur in a normal healthy intestine. The next important point is the change of bowel habit. Some people may have been twice a day or once every two days since they were young. As long as they maintain their habit, there is no obvious physical discomfort, and there is no major problem. However, if the number of unexplained cases increases, or if you want to pass but cannot pass stool, you must consider the health of your intestines. In addition, repeated hemorrhoids that do not heal, unexplained anemia, weight loss, and unexplained stomach pain must go to the hospital for a specialist examination as soon as possible, and you can rest assured after a clear diagnosis.
So do all changes in stool color, traits, habits, etc. predict colorectal cancer? You don't need to be too afraid of this. For example, blood in the stool, colorectal cancer patients and hemorrhoids patients will have blood in the stool, but the color of the blood in the stool is different. The blood in the stool of hemorrhoid patients is bloody bright red, which is not mixed with the stool. Most of the blood drips after the stool is discharged. This is because the hemorrhoid lesion is very close to the anus. If there is bleeding, the stool is the last thing encountered in the process of elimination. . The color of blood in the stool in patients with colorectal cancer is darker, and it is mostly mixed in the stool, because most of the bleeding part of colorectal cancer is far from the anus. Before the stool is discharged, there is already a distance of "close contact" with the stool. So it is a big mistake to treat hemorrhoids as soon as there is blood in the stool, or to think it is colorectal cancer as soon as there is blood in the stool. As for the changes in traits and habits, if it is really caused by temporary indigestion, a bad stomach or a change in the living environment, don’t be overly nervous. Just go to the hospital for some related examinations, such as stool tests and tumor indicators. Digital anus examinations by specialist doctors and various enteroscopes that can directly see the conditions in the intestines can help confirm the diagnosis.
Finally, I want to tell everyone that colorectal cancer is not an unpreventable tiger beast. As long as you pay more attention to cultivating healthy eating habits and pay more attention to your intestinal "messenger"-feces, you can find problems early Early treatment can maintain a healthy intestinal environment.
