The most obvious sign of colon cancer

There are no obvious signs of colorectal cancer. Colorectal cancer is a common malignant tumor of the digestive system. One of the more obvious signs is blood in the stool. Other symptoms include abdominal pain, weight loss, changes in bowel habits, and fatigue. If the symptoms persist, it is recommended to seek medical attention in time and take targeted treatment measures under the guidance of a doctor. The details are as follows:

1. Blood in the stool: One of the most obvious signs of colorectal cancer is blood in the stool. Blood in the stool usually appears as bright red or dark red blood mixed in the stool, which may be accompanied by mucus. This condition is often mistaken for hemorrhoids or other benign intestinal problems, but it may actually be an early sign of colorectal cancer. If this symptom occurs, you should seek medical attention in time and undergo a colonoscopy to confirm the diagnosis and early treatment.

2. Abdominal pain: Patients with colorectal cancer often experience abdominal pain, especially in the lower abdomen. The pain can be intermittent colic or persistent dull pain, and the pain may worsen as the disease progresses. The cause of abdominal pain is usually intestinal obstruction or inflammation caused by tumor growth. If you have persistent abdominal pain, you should see a doctor as soon as possible, confirm the cause through ultrasound or CT scan, and take treatment measures according to the specific situation.

3. Weight loss: Rapid weight loss without obvious reasons is an important sign of colorectal cancer. Weight loss may be caused by the tumor consuming a large amount of nutrients in the body or causing loss of appetite. If there is a significant weight loss in a short period of time, a comprehensive physical examination, including blood tests and imaging tests, is required to rule out malignant tumors.

4. Changes in bowel habits: Intestinal cancer can lead to changes in bowel habits, such as alternating constipation and diarrhea. Patients may find that the frequency of bowel movements increases or decreases, and the shape of stool changes, such as becoming thinner or shapeless. Long-term changes in bowel habits should be treated promptly, and fecal occult blood tests and colonoscopy should be performed to detect lesions early.

5. Fatigue: Due to chronic blood loss, colorectal cancer patients often suffer from anemia, which leads to fatigue. Patients may feel general fatigue and reduced endurance for work and daily activities. This fatigue cannot be relieved by rest. If fatigue occurs, a blood test should be performed. If anemia is found, further examination should be conducted to determine the cause and appropriate treatment should be given.

If the symptoms persist, it is recommended to seek medical attention in time and take targeted treatment measures under the guidance of a doctor. Maintaining good living habits and regular physical examinations can help detect and prevent colorectal cancer at an early stage.
