The doctor reminds: rectal cancer, 2 symptoms are the most obvious! Many people are careless

The human digestive system is very complex, with multiple organs involved in digestion, including the most well-known gastrointestinal tract.

In addition, the liver and pancreas also have outstanding performance contributions in digestion and absorption. In recent years, the incidence of digestive system cancer has continued to increase, especially the incidence of bowel cancer has not only increased, but also showed a younger trend.

Colorectal cancer, which is clinically referred to, mainly includes two types, that is, cancer that occurs in the rectum and colon. If rectal cancer can be detected at an early stage and treated aggressively, the five-year survival rate of patients can reach more than 70%.

On the contrary, if you have advanced rectal cancer, the survival rate will drop significantly, even less than 5%!

Although both rectal cancer and colon cancer belong to intestinal cancer, due to the special location of the rectum, it is relatively close to the anus. Rectal cancer can also show different symptoms during the stages of cancer development.

If the patient can catch the following two abnormalities, rectal cancer can be found early:

First, stool changes

Changes in bowel habits are one of the most typical symptoms of rectal cancer

After a tumor appears in the rectum, foreign body sensation and tumor secretions will continue to stimulate the intestinal tract, leading to disturbance of the patient's intestinal peristalsis, thereby changing the original bowel habits.

That is to say, patients often feel the urge to defecate, but the process of defecation is not smooth, and in severe cases there is even no defecation.

When it develops to a severe degree, bowel cancer continues to invade surrounding tissues, and patients will also experience multiple problems such as anal sphincter relaxation, anal incontinence, and obstruction.

Second, blood in the stool

Among all bowel cancer symptoms, blood in the stool is the most representative and most easily misunderstood by patients!

After most patients have symptoms of blood in the stool, the first thing they think of is not colon cancer, but suspects that they have diseases such as hemorrhoids and anal fissures.

But in fact, the blood in the stool of rectal cancer is obviously different from hemorrhoids. Usually, the hemorrhoids bleed in the form of dots, jets, and float above the stool. Some patients still feel pain when they defecate.

In rectal cancer, blood in the stool is different. Affected by the tumor in the early stage, the stool is likely to rub against the surface of the cancer, especially the more dry and hard stool, and obvious blood marks can be seen on the side of the stool.

After a certain stage of development, the discharged blood will be mixed with the stool, showing a red and dark red state, and the stool is often mixed with mucus.

In some patients, blood clots may be expelled during the process of blood in the stool. The more advanced it is, the more obvious the symptoms of blood in the stool will be. Even if there is no stool discharge, the mucus-like or pus-like bloody stool is directly pulled out, accompanied by a strong stench.

This is caused by the development of cancer, leading to tissue necrosis and erosion.

The development of bowel cancer takes a certain amount of time. In addition to the unhealthy eating habits of patients, genetic factors and age are also one of the murderers behind the scenes.
