What are the symptoms of anal cancer?

Anal cancer is a malignant tumor originating from the skin or underlying tissues of the mucosa in the anal region. In general, symptoms of anal cancer may include anal pain, bleeding, changes in bowel habits, anal itching, and lumps. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific details are as follows:

1. Anal pain: In early stages, anal cancer may not present obvious symptoms. However, as the tumor grows, patients may experience pain or discomfort in the anal area, possibly due to tumor compression of surrounding nerves or inflammation.

2. Bleeding: Rectal bleeding is common in patients with anal cancer. The blood may appear bright red or dark red, often mixed with stool or dripping after defecation. This typically results from rupture of blood vessels on the tumor surface or tumor invasion into the anal mucosa.

3. Changes in bowel habits: Anal cancer may lead to alterations in bowel patterns, including constipation, diarrhea, or narrowing of stool. These changes may occur because the tumor obstructs normal function of the rectum or anus, interfering with stool passage.

4. Anal itching: The presence of a tumor may irritate the skin around the anus, causing itching. Additionally, the tumor may increase secretions such as blood, pus, or mucus, which can further irritate the anal area and worsen itching.

5. Lump: Some patients may feel a hard mass in the anal area, which is often a direct sign of anal cancer. The size and location of the lump depend on the stage and specific type of the tumor.

If diagnosed with anal cancer, patients should follow medical advice regarding treatments such as surgery or radiation therapy, which can help control the disease. In daily life, maintaining good personal hygiene and getting adequate rest can further support recovery.
