The most obvious sign of colon cancer

As a common digestive system malignancy, the symptoms of colorectal cancer may vary from person to person, but there are some obvious signs. Common symptoms include changes in bowel habits, blood in the stool, abdominal pain and discomfort, weight loss and loss of appetite, intestinal obstruction, etc. The specific analysis is as follows:

1. Changes in bowel habits: Patients with colorectal cancer often experience changes in bowel habits, such as constipation, diarrhea, or alternating between the two. This is because the tumor grows in the intestine, affecting the normal peristalsis and emptying of the intestine.

2. Blood in the stool: Patients with colorectal cancer may have blood in the stool, which may be bright red or dark red and often mixed with feces. This is caused by ruptured blood vessels or bleeding on the surface of the tumor.

3. Abdominal pain and discomfort: People with colorectal cancer may experience persistent abdominal pain or discomfort, which is caused by the tumor compressing or invading the intestinal nerves. The degree and location of the abdominal pain may vary depending on the location and size of the tumor.

4. Weight loss and loss of appetite: Since the tumor consumes the body's nutrients, colorectal cancer patients may experience weight loss and loss of appetite. At the same time, the tumor may also cause digestive system symptoms such as nausea and vomiting.

5. Intestinal obstruction: In the late stage of colorectal cancer, the tumor may block the intestines, leading to intestinal obstruction. Symptoms such as abdominal distension, abdominal pain, vomiting and constipation may occur. Intestinal obstruction is a serious complication of colorectal cancer and requires prompt medical treatment.

These symptoms are not specific to bowel cancer, but if you experience any one or more of these symptoms, it is recommended that you seek medical attention for detailed examinations to confirm the diagnosis. Early detection and treatment of bowel cancer is crucial to improving the patient's survival rate.
