Cáncer anal
Anal cancer is uncommon. Caught early, it's highly treatable.
Modern treatment cures the majority of cases when found before they spread. The most important step is getting unusual symptoms evaluated.

Anal cancer develops when abnormal cells grow uncontrollably in the anal canal. It's far less common than colorectal cancer, but it shares an important trait: outcomes depend heavily on how early it's found. Most patients diagnosed at an early stage do well with treatment, often without needing surgery.

What Is Anal Cancer?

Anal cancer arises in the anal canal, the short tube at the end of the digestive tract. The most common type by far is squamous cell carcinoma, which begins in the cells lining the anus. Less common types include adenocarcinoma, basal cell carcinoma, and melanoma.

Although anal cancer is uncommon (around 9,000 to 10,000 new US cases each year), the rate has been slowly rising. Awareness of the symptoms and risk factors is what gets people in the door before a small problem becomes a big one.

The HPV Connection

The single biggest driver of anal cancer is human papillomavirus (HPV), the same virus most responsible for cervical cancer.

~85%
of anal cancers are linked to HPV infection. This is why HPV vaccination, screening for high-risk groups, and treating precancerous changes early all matter.

Most people exposed to HPV clear it without consequence. In some, the virus persists and causes cellular changes (anal dysplasia) that, over years, can develop into cancer. Recognizing this connection is what makes anal cancer one of the more preventable cancers, especially for people in higher-risk groups.

Síntomas a tener en cuenta

Some patients have no symptoms at all. Others notice changes that warrant a closer look. Common signs include:

Cambios en los hábitos intestinales
Anal itching or discomfort that doesn't resolve
Un bulto o masa cerca del ano
Hemorragia rectal o sangre en las heces
Dolor persistente en la región anal
A feeling of fullness or pressure in the anal area
Unusual discharge from the anus

These symptoms are far more often caused by benign conditions like hemorrhoids or fissures. But because they overlap, an evaluation is the only way to know for sure. Persistent symptoms deserve a real exam.

Risk Factors

Several factors raise the likelihood of developing anal cancer.

HPV infection
The strongest single risk factor. Persistent infection with high-risk HPV strains drives most anal cancers.
Anal dysplasia
Precancerous changes in the anal cells, usually HPV-driven. Detectable and treatable before they become cancer.
Weakened immune system
HIV-positive individuals and people on immunosuppressive medications (organ transplant recipients, certain autoimmune treatments) face significantly higher risk.
Fumar
Roughly doubles the risk of anal cancer. The most modifiable risk factor on this list.
Age
Most cases are diagnosed in adults over 50. Average age at diagnosis is around 60.
Sexual history
Multiple sexual partners and receptive anal intercourse both raise HPV exposure and therefore risk.
History of HPV-related cancers
Women with a history of cervical, vaginal, or vulvar cancer face elevated anal cancer risk due to shared HPV exposure.
Note on screening: Anal Pap smears (similar to cervical Pap smears) can detect dysplasia early in high-risk groups. Talk to Dr. Chung about whether routine screening makes sense for you, especially if you're HIV-positive, immunosuppressed, or have a history of HPV-related conditions.

How Anal Cancer Is Diagnosed

If symptoms or risk factors warrant evaluation, Dr. Chung may recommend one or more of the following:

Digital rectal exam (DRE)
A brief physical examination to check for abnormalities in the anal canal. Quick and informative as a first step.
Anoscopy
A small, hollow tube with a light is inserted into the anus to detect abnormal tissue. Suspicious areas can be biopsied for definitive diagnosis.
High-resolution anoscopy (HRA)
A more detailed exam used to look for dysplasia, especially in high-risk individuals.
Endoscopy
A flexible scope provides a detailed view of the anal and rectal tissue beyond what anoscopy can see.
Imaging tests
PET scans, MRI, CT scans, and ultrasounds may be used to determine whether cancer has spread beyond the anus and to plan treatment.

Opciones de tratamiento

Treatment depends on the stage of the disease and your overall health. Modern care has shifted dramatically in the last few decades, with chemoradiation now the first-line approach for most cases.

First-line for most cases
Chemoradiation (combined chemotherapy and radiation)
For most stages of anal cancer, the standard treatment is a combination of chemotherapy drugs and radiation therapy delivered together over several weeks. This approach (often called the Nigro protocol) cures most early-stage cancers without surgery and preserves anal function.
Cirugía
Local excision or abdominoperineal resection (APR)
Surgery may be used for very small early tumors that can be removed with healthy margins, or for cases that don't respond to chemoradiation. APR (full removal of the anus and rectum, with a permanent colostomy) is reserved for advanced or recurrent disease.
Inmunoterapia
Targeted treatment for advanced cases
Treatments that help the body's immune system recognize and attack cancer cells. Used primarily for advanced or recurrent anal cancer that hasn't responded to standard therapy.

Dr. Chung will work closely with you and any oncology team involved to determine the best strategy based on your specific stage, health, and goals.

Outlook and Recovery

Outcomes for anal cancer have improved significantly with modern treatment. When found before it has spread, the majority of patients respond well to chemoradiation and avoid surgery entirely. Even more advanced cases have meaningful treatment options.

The biggest factor in a good outcome is catching it early. That's why every persistent or unexplained anal symptom deserves an evaluation, and why high-risk groups should talk to a specialist about appropriate screening.

Get the evaluation that matters

If you're noticing symptoms or have risk factors for anal cancer, getting evaluated quickly is the single most important thing you can do. Dr. Chung handles these conversations with the matter-of-factness they deserve.
