Edating cancer, also known as colorectal cancer, has ranked second in the incidence of tumors in the eastern region. 80%~ 90%of bowel cancer is generated by “polyps”, from polyps to cancer. This process is long and takes at least 10 years. If hidden dangers can be excluded in time during this period, you can greatly reduce the risk of evil.
The emergence of intestinal polyps has something to do with genetic genetic, inflammatory stimulation, environment and diet. For high -risk groups with polyp family history and high -risk people who have polyps, if there are suddenly the following three symptoms to come to the door, Beware is the manifestation of polyp cancer:
1. Blood in the stool
Whether it is intestinal polyps or intestinal cancer, after the patient’s development period, patients may have symptoms such as blood, mixed blood, and mucus blood stools.
Especially after the intestinal cancer enters the middle and late stages, due to cancer destroying blood vessels in the intestine, and some cancer tissues due to ischemia erosion and necrosis, the amount of intestinal hemorrhage of patients will gradually increase. Patients can discharge mixed blood.
After the intestinal cancer is combined with infection and inflammation, the patient’s bowel movement will change, and even pus and pus will be discharged. Sometimes the feces may be mixed with bad tissues and blood clots;
Second, change habits change
The mass is a foreign body in the intestine. In the process of forming and continuous growth, it will cause a certain stimulation to the intestinal mucosa. At the same time, it can also change the secretion of intestinal mucosa, resulting in changes in the frequency of defecation in the patient.
According to clinical data, the earliest manifestations of colorectal cancer patients in the earliest medium -term are the pseudo -diarrhea, frequent defecation, and unspecified bowel movements.
Even patients can frequently appear in the night at night, but each defecation is not large, and there are many stools;
Third, the stool becomes thinner
In addition to the inadequate dung, mucus, and mixed blood stools, after the intestinal cancer enters the middle and late stages, the patient may also excrete the stool for molding, but this kind of feces are often small flats, small thin strips, or the stool side. There are obvious depression traces.
The reason why this is because cancer has increased to a certain extent, and even infiltrates the intestinal wall towards the intestinal wall. It causes abnormal narrowing and obstruction of the intestinal cavity. In the process of defecation, the patients have caused puffing to the stool. Press, and then change the shape of the feces.
In the case of severe intestinal obstruction, patients may also have symptoms such as difficulty in defecation, constipation, and abdominal pain.
