The most obvious symptoms and manifestations of colon cancer

There are no obvious symptoms and manifestations of colorectal cancer. Colorectal cancer is a common malignant tumor of the digestive system. Its obvious symptoms and manifestations include changes in bowel habits, blood in the stool, abdominal pain, weight loss and anemia. 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. Changes in bowel habits: Patients with colorectal cancer often experience symptoms such as increased bowel movements, alternating constipation and diarrhea, etc. If there is a significant change in bowel habits, a colonoscopy should be performed as soon as possible to rule out the possibility of colorectal cancer. Such examinations can help doctors detect tumors or polyps in the intestine, allowing for early intervention and treatment.

2. Blood in the stool: Colorectal cancer is often accompanied by blood in the stool, which is usually dark red or mixed with mucus. If blood in the stool occurs, you should see a doctor immediately for a fecal occult blood test and related tests to determine the cause. The doctor may recommend a colonoscopy to identify the bleeding point and rule out other possible causes of bleeding, such as hemorrhoids or inflammatory bowel disease.

3. Abdominal pain: Patients with colorectal cancer often experience dull abdominal pain or cramps, mostly in the lower abdomen. If the abdominal pain worsens or persists, imaging examinations such as CT or MRI should be performed as soon as possible to confirm the diagnosis. These examinations can help doctors understand the specific location and size of the tumor and provide a basis for further treatment.

4. Weight loss: Rapid weight loss without obvious reasons is a common manifestation of colorectal cancer. If you experience unexplained weight loss, you should undergo a comprehensive physical examination as soon as possible, including blood tests and imaging tests. The doctor will determine whether there is colorectal cancer or other potential diseases based on the test results and develop a corresponding treatment plan.

5. Anemia: Chronic bleeding caused by intestinal cancer can lead to anemia, which manifests as fatigue, pale complexion, etc. If anemia symptoms occur, a blood test should be performed to determine whether chronic bleeding exists and to treat the cause. The doctor may recommend iron supplementation or blood transfusion to correct the anemia, while actively treating the primary disease that causes the bleeding.

To ensure early detection and treatment, you should be highly vigilant about these symptoms and seek medical attention in a timely manner. The doctor will take targeted treatment measures based on the patient's specific situation to improve the treatment effect and the patient's quality of life.
