There is a lump outside the anus?

There is a lump on the right side of the anus near the coccyx that has been present for at least five years.
During this time, I have experienced rectal bleeding and pain during bowel movements, and I sought medical attention.
At that time, I was diagnosed with hemorrhoids and treated with topical medications and suppositories, which improved the bleeding symptoms, but the lump did not decrease in size.
However, I am still experiencing rectal bleeding and pain (I thought it was not serious, so I did not seek further medical attention).
It seems that the lump has been getting larger over time.
It usually does not hurt, but it becomes very painful after sitting for extended periods (like a four-hour train ride).
Could this possibly be a tumor?

More Info

When it comes to external anal masses, particularly those that have been present for an extended period, such as five years in your case, it is essential to approach the situation with caution and seek medical advice. The symptoms you describe, including a lump near the tailbone, rectal bleeding, and pain during bowel movements, warrant further evaluation by a healthcare professional.

Symptoms and Causes
External anal masses can arise from various conditions, including:
1. Hemorrhoids: These are swollen veins in the lower rectum or anus and can cause pain, itching, and bleeding during bowel movements. Given that you have previously been diagnosed with hemorrhoids, this could be a possibility, especially if the mass has not changed significantly in size.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing hard stools. They can lead to pain and bleeding but typically do not present as a mass.

3. Skin Tags: These are benign growths that can occur after repeated irritation or inflammation, often associated with hemorrhoids.

4. Abscesses: An anal abscess is a painful condition that occurs when a cavity filled with pus forms near the anus, often due to infection.

5. Fistulas: These are abnormal connections between the anal canal and the skin, often resulting from an abscess.

6. Tumors: While less common, both benign and malignant tumors can present as anal masses. Symptoms such as persistent bleeding, changes in bowel habits, or significant pain should raise suspicion for a more serious condition.

When to Seek Help
Given your history of rectal bleeding and pain, along with the persistence and potential increase in size of the mass, it is crucial to seek medical attention. Here are some reasons to consult a healthcare provider:
- Persistent Symptoms: If you experience ongoing bleeding, pain, or changes in bowel habits, these are red flags that should not be ignored.

- Changes in Size or Appearance: If the mass appears to be growing or changing in texture, this could indicate a need for further investigation.

- New Symptoms: The development of new symptoms, such as significant pain after prolonged sitting, should prompt a medical evaluation.

Diagnostic Approach
A healthcare provider will likely perform a thorough examination, which may include:
- Physical Examination: A visual and physical examination of the anal area to assess the mass.

- Anoscopy or Sigmoidoscopy: These procedures allow for a closer look at the anal canal and rectum, helping to identify any underlying issues.

- Imaging Studies: In some cases, imaging studies such as ultrasound or MRI may be necessary to evaluate the mass further.

Conclusion
While the mass you describe may be related to hemorrhoids or another benign condition, the persistence of symptoms and the potential for growth necessitate a professional evaluation. Early diagnosis and treatment are crucial, especially if there is any concern for malignancy. Please do not delay in seeking medical attention, as timely intervention can lead to better outcomes and peace of mind.
