4 major manifestations of early symptoms of colorectal cancer. Can colorectal cancer be prevented and treated?

Because colorectal cancer is not very obvious in the early stages, it is difficult for people to detect the presence of colorectal cancer in the early stages. Below, the editor will introduce some early symptoms of colorectal cancer. From these symptoms, we can see whether we have colorectal cancer. If we really have colorectal cancer, we should seek medical attention in time. This is responsible for our lives. What are the early symptoms of colorectal cancer?

1. Blood in the stool

Early symptoms of colorectal cancer include blood in the stool, because the lesion is relatively close to the anus. The blood is mostly bright red or dark red, and the blood is separated from the stool. When the amount of blood is large, the stool is brownish red. About 30% of patients with right-sided colon cancer have visible blood in the stool. This is also one of the early symptoms of colorectal cancer.

2. Abdominal distension and pain

The early symptoms of colorectal cancer are caused by intestinal dysfunction or intestinal obstruction, mostly concentrated in the middle and lower abdomen, usually dull pain or bloating. The obvious manifestation is a gradual aggravation.

3. Increased bowel movement frequency

The early symptoms of colorectal cancer include an increase in the frequency of bowel movements. The frequency of bowel movements will increase more and more often in patients with rectal cancer. However, basically, each bowel movement is not large, and the feces are mostly blood and thinner mucus. And there is always a feeling that the bowel movements are always non-stop. The frequency of bowel movements will increase only when the tumor is getting bigger and bigger, and erosion or infection occurs. There will also be constipation or diarrhea for unknown reasons. If the tumor protrudes into the rectal cavity, this will cause the intestinal cavity to be relatively narrow, and the stool will be deformed or smaller. At this time, the stool is generally flat in shape, and occasionally some red blood will be attached to the stool.
