The intestine is a very important digestive organ of the human body. In addition to the functions of nutrient absorption and detoxification, it also has a certain immune function. When there is a disease in the intestine, it will bring great harm to the body. And bowel cancer is the most serious and frightening of these lesions, because once the disease is not detected in time, the probability of survival of the patient is very small.

Therefore, for diseases such as colon cancer, prevention must be greater than cure. The prevention of colon cancer should not only be reflected in the details of living habits, but also pay attention to some signals sent by your body. If we can catch the signs of danger in time, we can stifle such terrible diseases as bowel cancer in the cradle.

What signals does the body send when bowel cancer comes?

Mr. Wang is an office worker. He works day and night every day, and his endless entertainment keeps his body in a sub-healthy state. For this, Mr. Wang himself is aware of it, but he really has no time to pay attention to his own health.

Until recently, a medical examination organized by the company brought a bolt from the blue to Mr. Wang's life. In the gastroenteroscopy project of the physical examination, the doctor believed that some tumor-like substances appeared in Mr. Wang's rectum, which had the possibility of cancerous transformation and needed further examination.

When Mr. Wang heard the doctor said that he might have cancer, he was really nervous, but he was lucky, he shouldn't be so unlucky, right? However, further examination results made Mr. Wang's whole body collapse directly. The results showed that Mr. Wang had advanced rectal cancer, and it was recommended to undergo chemotherapy immediately.

Seeing the result, Mr. Wang broke down and cried. He thought that his body was really not healthy enough, but he never thought that he would get cancer, and it was already late when he found out. The doctor comforted Mr. Wang that although he was diagnosed with rectal cancer, he could not give up treatment and should face it positively.

After Mr. Wang became more stable, the doctor began to communicate with Mr. Wang. During the conversation, the doctor found that in fact, Mr. Wang's rectal cancer did not appear suddenly, but had already had relatively significant signs.

About a few months ago, Mr. Wang's stool appeared abnormal. First of all, unlike before, Mr. Wang's stool became very thin, but this did not attract Mr. Wang's attention. But there is another change that Mr. Wang is more concerned about, that is, the color of his feces has become very dark, and sometimes blood is mixed with it.

Since he suffered from hemorrhoids before, Mr. Wang didn't care much about it. He thought that his condition was probably caused by the recurrence of hemorrhoids, and he didn't think about it. But what Mr. Wang did not expect was that this was actually a distress signal sent by his body to him.

In order to understand why patients with rectal cancer have blood in the stool, let's first introduce the location of the rectum. The rectum is located at the end of the large intestine, two centimeters inside the anus. After rectal cancer, the inside of a patient's rectum may be filled with tumors. The excretion of stool must pass through the rectum, and the friction between the stool and the tumor on the rectal wall causes them to bleed, eventually causing the patient to have blood in the stool.

As the disease worsens, the space left for stool to pass through the patient's rectum becomes narrower and narrower, which will cause the patient's stool to become thinner than normal, and in severe cases, even the stool will not be formed.

The above symptoms of rectal cancer are not typical. In particular, some patients with hemorrhoids will think that their defecation-related physical abnormalities are caused by hemorrhoids, thus missing the best time for treatment.

But there's another symptom associated with rectal cancer that's hard to ignore: bowel obstruction. Intestinal obstruction refers to the difficulty of normal passage of intestinal contents due to the presence of some foreign bodies in the intestinal tract. For patients with rectal cancer, these patients may experience symptoms of bowel obstruction due to the presence of tumors in the bowel.

Many patients think that bowel obstruction and constipation are easy to confuse, but this is not the case. Intestinal obstruction contains many symptoms, the more typical ones are abdominal pain, acid-base imbalance, etc. In severe cases, there may even be abnormal heart and lung function. The symptoms of constipation are relatively simple, mainly manifested as inability to defecate normally. In fact, intestinal obstruction is a relatively acute disease, which is why it is often difficult for patients to ignore intestinal obstruction.
