Colon cancer has many harmful effects, and if not treated in time, it may induce colon malignancy. Colon cancer has symptoms such as diarrhea, abdominal pain, constipation, abdominal distension, and weight loss. What are the harms caused by colon cancer? Let's take a look at the following introduction.

What are the dangers of colon cancer?

1. A lot of blood in the stool:

Blood in the stool is one of the main clinical manifestations of this disease, and the amount of blood in the stool is also an indicator of the severity of the disease. The heavy blood in the stool here refers to a large amount of intestinal bleeding in a short period of time, accompanied by an increased pulse, a decrease in blood pressure and a decrease in hemoglobin, which requires blood transfusion treatment.

2. Intestinal stenosis:

It often occurs in cases with extensive lesions and a duration of more than 5-25 years. The location is mostly in the left colon, sigmoid colon or rectum. It is generally asymptomatic clinically. In severe cases, it can cause intestinal obstruction. When intestinal stenosis occurs in this disease, be alert to tumors and distinguish between benign and malignant.

3. Intestinal perforation:

It is mostly a complication of toxic intestinal dilatation, but may also be severe, often occurring in the left colon. The use of corticosteroids is considered a risk factor for intestinal perforation.

4. Toxic intestinal dilatation:

This is a serious complication of the disease, which often occurs in patients with pancolitis. The mortality rate can be as high as 44%. The clinical manifestations are rapid deterioration of the disease, obvious symptoms of poisoning, accompanied by diarrhea, abdominal tenderness and rebound pain, weakened or disappeared bowel sounds, increased white blood cell count, and easy complications of intestinal perforation.

5. Colon malignancy:

About 5% of cases develop malignant transformation, which is more common in patients with lesions involving the entire colon, onset in childhood and a history of more than 10 years.
