How do I know if I have Anal Cancer?

TL;DR: Anal cancer symptoms often mimic common, benign conditions like hemorrhoids, making professional evaluation essential for accurate diagnosis. Key indicators include persistent rectal bleeding, a lump near the anal opening, or unexplained changes in bowel habits that do not resolve with standard treatment.

What are the early signs of anal cancer?

Many individuals with anal cancer initially mistake their symptoms for less serious issues like fissures or hemorrhoids. Because anal cancer presents with non-specific symptoms, it is vital to monitor for changes that persist beyond a few weeks. Common clinical presentations include:

• Rectal bleeding or spotting during bowel movements.


• A palpable lump or mass near the anal canal.


• Persistent anal itching (pruritus ani).


• Pain or a sensation of fullness in the anal area.


• Changes in bowel habits, such as increased frequency or narrowing of the stool.

When should I see a doctor about anal cancer?

If you notice any of the symptoms listed above, you should schedule an appointment with your primary care provider or a gastroenterologist. When speaking with them, be specific about how long the symptoms have lasted and whether they are worsening. If you are at higher risk—such as having a history of HPV infection or being immunocompromised—mention this specifically, as these are known risk factors for anal cancer.

How is anal cancer diagnosed?

To investigate a potential anal cancer diagnosis, physicians typically perform a digital rectal exam (DRE) to feel for abnormalities. If further investigation is required, they may suggest an anoscopy (using a small scope to view the anal canal) or a biopsy, which is the definitive way to confirm or rule out anal cancer. Diagnostic imaging like a pelvic MRI or CT scan may also be utilized to assess the extent of the disease.

What are the red flags for urgent evaluation?

Seek urgent medical attention if you experience significant, unexplained weight loss, severe pelvic pain, or bowel obstruction. If your concerns are dismissed, advocate for yourself by requesting a referral to a colorectal surgeon or an oncologist, noting that you are seeking a definitive investigation to rule out anal cancer.

Next steps

• Schedule a physical examination with your primary care provider to discuss your specific symptoms.


• Request a referral to a colorectal specialist if symptoms persist after initial treatment for common conditions like hemorrhoids.
