What are the 5 major symptoms of early colorectal cancer

In the early stages of rectal cancer, there are usually more than just the five major symptoms. The more common symptoms include changes in bowel habits, bloody stools, abdominal pain or discomfort, abnormal flatulence, weight loss, etc. You should seek medical attention promptly and follow the doctor's advice to choose the appropriate treatment method.

1. Changes in bowel habits: Early stage colorectal cancer often manifests as changes in bowel habits, such as constipation, diarrhea, and a feeling of incomplete emptying during bowel movements. If such changes persist, you should be alert.

2. Bloody stool: Early stage rectal cancer is often accompanied by bloody stool, which is manifested as bright red blood or dark red blood clots in the stool. The degree of bloody stool may vary depending on the location and size of the tumor, but any unexplained bloody stool should be treated promptly.

3. Abdominal pain or discomfort: Abdominal pain or discomfort in the early stage of rectal cancer may be caused by the tumor compressing or blocking the intestine. This kind of abdominal pain is usually long-term, unrelated to diet, and difficult to relieve.

4. Abnormal gas discharge: Patients with early stage rectal cancer may experience abnormal gas discharge, such as frequent farting or abnormal odor when passing gas. This is because the tumor blocks or compresses the intestines, causing the gas to be unable to be discharged normally.

5. Weight loss: Patients with early stage colorectal cancer often experience unexplained weight loss or weight loss. This is because the tumor consumes the body's nutrients, leading to weight loss.

The above symptoms are not exclusive to rectal cancer and may also be related to other diseases. If you experience the above symptoms or other discomfort, it is recommended to seek medical attention for further examination and diagnosis.
