"Stool" is the waste discharged by the human body after digesting food. The remaining food residues that have no value will enter the large intestine and accumulate continuously, eventually turning into feces and being discharged.
It is for this reason that everyone does not pay much attention to stool, and each time after the stool has not been carefully observed.
As everyone knows, stool is known as a barometer of intestinal health. Whether it is acute intestinal disease or chronic disease , it can affect the shape of stool. Even after the intestine becomes cancerous, the preliminary judgment can be made through stool!
If the following four abnormalities suddenly appear in the stool recently, you should be careful that it is a signal from bowel cancer:
First, how did the stool shape change?
As mentioned above, food residues will continue to accumulate in the large intestine, and the intestinal mucosa will absorb the water in the mucous membrane, and finally the stool will be formed. It is important to know that the intestine is in a cylindrical state. Under normal circumstances, the human excreted stool should also be soft and hard moderate. After being affected by diet and acute bacterial infections, changes may occur temporarily, such as unshaped stools and loose watery stools , which are common situations.
Especially cancerous changes that occur in the rectum. As the cancer continues to grow, the space of the intestinal cavity will become abnormally narrow. When the stool passes, the cancer will squeeze the stool, which will cause the shape of the stool to change. For example, pencil-like stools, flat-striped stools, and dented stools are all abnormalities.
Second, why is bowel movement becoming more difficult?
Difficulty with bowel movement should first consider the problem of constipation, especially dry stools, difficult to discharge, stool less than or equal to 2 times a week, is the typical symptoms of constipation.
If the symptoms of tenesmus suddenly appear recently , this may not only be a constipation problem, but a signal that bowel cancer is coming. The so-called tenesmus, it means that the bowel movement is very urgent and it feels imminent, but the amount of stool output per time is not large, the stool is difficult to discharge, or there is no stool.
The reason for this is that the fecal storage space is reduced due to cancer and the fecal output channel is blocked .
At the same time, the tumor may also compress and stimulate the end of the large intestine , and repeatedly affect the defecation receptors, resulting in frequent bowel movements, but the stool cannot be discharged normally.
When cancer forms intestinal obstruction , it will aggravate these symptoms.
Third, how has the habit of bowel changed?
In addition to the symptoms of tenesmus, patients may also have symptoms similar to irritable bowel, such as constipation, diarrhea, or alternating between the two. At the same time, the patient's previous bowel habits were completely disrupted, from regular bowel movements to multiple bowel movements a day, or only one bowel movement in a few days.
The reason for this is mainly related to intestinal stenosis and cancer irritation to the intestinal mucosa .
Fourth, why is there blood?
Many people think of common diseases such as hemorrhoids and anal fissures for the first time after blood in the stool appears!
Perianal disease is indeed one of the causes of blood in the stool and the patient may feel pain during the defecation process. As the cancer continues to grow, the surface of the cancer is likely to rupture, bleeding, and infection. If the blood is close to the anus, the blood will be mixed with the stool and will be bright red or dark red in color. When it develops to an advanced stage and is accompanied by infection of bowel cancer, pus-like bloody stools and mucus-like blood stools may appear .
Of course, symptoms alone cannot directly determine whether cancer has occurred in the intestines. It can only be diagnosed after passing a professional examination. Colonoscopy and digital anal examination are common screening methods.
After being diagnosed with colorectal cancer, no matter what stage you are in, you need to actively cooperate with the doctor for treatment .
