10 symptoms and warning signs of colorectal cancer

The early symptoms of colorectal cancer may not be obvious, but there are some signs that can help us detect it early.

1. Changes in bowel habits: If you find that your bowel habits suddenly change, such as alternating constipation and diarrhea, or a significant increase or decrease in the number of bowel movements, this may be a sign of colon cancer. Our intestines are like a precise clock, and any abnormal changes should not be ignored.

2. Changes in stool shape: Thin stools or abnormal shapes may also be a precursor to colon cancer. Tumors in the intestine may cause the intestinal cavity to narrow, thus affecting the shape of the stool. If you find this, it is recommended to see a doctor as soon as possible.

3. Blood in the stool: Blood in the stool is an obvious warning sign. Although blood in the stool may be caused by hemorrhoids, it may also be a symptom of colon cancer. Especially when the blood is dark in color, it needs to be taken seriously.

4. Abdominal pain and bloating: Persistent abdominal pain and bloating may also be early symptoms of colon cancer. Some people may mistake it for ordinary indigestion, but if this discomfort persists or gradually worsens, you should seek medical attention as soon as possible.

5. Sudden weight loss: Unexplained weight loss is a warning sign. Colon cancer may cause the body to be unable to absorb nutrients normally, resulting in weight loss. If you find that you have lost a lot of weight without deliberately losing weight, it is recommended to have a comprehensive health check.

6. Fatigue and weakness: Patients with colorectal cancer often feel tired and weak. This may be due to chronic blood loss caused by the tumor, which in turn causes anemia. Long-term fatigue not only affects the quality of life, but may also be a distress signal sent by the body.

7. Anemia: Anemia caused by chronic blood loss is a potential symptom of colorectal cancer. Anemia can cause dizziness, fatigue, and pale skin. If you have these symptoms, especially if they are accompanied by other signs of colorectal cancer, you should see a doctor as soon as possible.

8. Nausea and vomiting: Persistent nausea and vomiting may be caused by intestinal obstruction caused by colon cancer. This condition not only affects appetite and nutritional intake, but may also lead to more serious health problems.

9. Loss of appetite: A sudden loss of appetite may be a hidden symptom of colorectal cancer. Tumors may affect the normal function of the digestive system, leading to loss of appetite. If you find yourself losing interest in food, you should pay attention to it.

10. Intestinal obstruction: Intestinal obstruction is a serious symptom of colorectal cancer. The tumor may cause partial or complete blockage of the intestine, which can cause severe abdominal pain, vomiting, and bloating. This situation requires immediate medical attention.

Early detection of colorectal cancer is crucial to the effectiveness of treatment. If you have any of the above symptoms, it is recommended to see a doctor as soon as possible. Through timely physical examinations and health management, we can better prevent and deal with colorectal cancer. Maintaining a healthy lifestyle and regular health checks are effective ways to prevent colorectal cancer.
