Obviously it is hemorrhoids, why is it related to bowel cancer?
This is a problem that many bowel cancer patients who are treated in the proctology department are difficult to understand, obviously they have hemorrhoid-like manifestations, but the doctor recommends that they undergo colonoscopy, and finally they are diagnosed as "bowel cancer".
Obviously, the intestine has undergone cell carcinogenesis, why is it similar to hemorrhoids? And how to distinguish the difference between hemorrhoids and bowel cancer?

First of all, we must understand that the so-called bowel cancer refers to the cancerous changes that occur in the segments of the large intestine, which includes cancerous changes in the rectum, colon and other areas. The large intestine is responsible for storing food scraps, turning them into feces, and eventually excreting them from the body with the anus.
It is also because of this relationship that the symptoms of hemorrhoids and bowel cancer are very similar. If you want to distinguish whether it is hemorrhoids or bowel cancer, you can start from the following aspects:
1. Stool habits
Hemorrhoids are lesions that appear on the perianal area, which does not affect the patient's defecation pattern, but a small number of patients are worried that defecation will cause pain, and deliberately hold the stool and have symptoms of constipation.
However, bowel cancer is not the same, whether it is colon or rectal cancer, after the formation of tumors will cause irritation to the intestinal mucosa, resulting in intestinal peristalsis, mucous membrane secretion changes, and then affect the law of defecation, patients will have more and more times of defecation, frequent pseudo-diarrhea, and accompanied by a feeling of impurity.
After the advanced stage, due to cancer, the intestine becomes more and more narrow, and many abnormal manifestations such as difficulty in defecation and constipation can also occur;
2. Stool shape
Due to the narrowing of the intestinal lumen caused by cancer, the patient will not only have symptoms similar to constipation, but the tumor may also cause compression in the stool, resulting in changes in the shape of the stool, such as the patient will discharge flat stools, thin stools, stools with dents on one side, and so on.
However, hemorrhoids are not the same, although it appears on the perianal perianal area, but in the front of the anus when the feces are discharged, its shape has been formed, so the hemorrhoids do not affect the shape of the stool;
3. Pain gap
Hemorrhoids do cause pain, but the pain is only limited to the anus and perianal area, and it occurs in the process of defecation. When the patient's bowel movements are over, the pain gradually disappears. Bowel cancer, on the other hand, causes different pain, not only causing perianal pain due to infiltration of the canal, but also abdominal pain.
This abdominal pain comes from many aspects such as cancerous stimulation of the intestine, causing compression and adhesion of surrounding tissues, causing organ obstruction, etc., abdominal pain can become more and more serious as the disease progresses, the pain time becomes longer and longer, and even the continuous pain occurs throughout the day without interruption;
4. Look at the bloody stool
Hemorrhoids combined with blood and stool are passive, appearing in the process of defecation in patients, the blood appears bright red, floating on the surface of the stool, or there is a spray of blood, dripping blood.
When the patient's bowel movements are completely over, the bleeding will gradually stop. The bowel cancer blood is active, it occurs in the intestine, the patient has a variety of blood and stool symptoms, such as fecal occult blood, mixed mucus blood stool, pus-like blood stool and so on.
Written in the end: In general, the symptoms of hemorrhoids and bowel cancer are indeed very similar, and if the patients only observe it themselves, it is easy to make a wrong judgment and then delay treatment.
Therefore, in the clinical view, as long as there is a bloody stool that lasts for more than two weeks, intermittent or continuously occurs, the regularity of defecation changes, and abdominal pain need to be examined in time to avoid missing the best time for diagnosis and treatment of the disease.
