What you need to know about anal cancer
- The anus is the last part of your digestive system. It is the opening through which stool exits the body. Anal cancer happens when damage occurs to cells in this area, causing abnormal cells to form and grow.
- One of the biggest risk factors for anal cancer is human papillomavirus (HPV). This disease spreads through sexual contact. You can lower your risk of HPV and anal cancer by receiving an HPV vaccination.
- Don’t let shame or embarrassment stop you from talking to a doctor about anal cancer. Catching it early allows you to receive timely care.
How to talk to your doctor about anal cancer
It’s natural to have a lot of questions after receiving an anal cancer diagnosis. We are here for you with the answers and reassurance you need.
You might want to ask your doctor about:
- Additional testing that may be necessary to confirm a diagnosis or plan treatments
- Cancer stage, the size of the cancer and if it is likely to spread
- Treatment options, including nonsurgical therapies for early-stage cancers
- Potential treatment side effects and what we can do to help you get relief
- Support to help you cope with the ways anal cancer may affect your daily life
Making care decisions can be challenging. Our team is here for you. We explain tests and treatments in ways you can understand and describe how they work. You can also bring family members or trusted friends with you for support.
Understanding Anal Cancer
We have experience treating these common and complex forms of anal cancer:
- Squamous cell carcinoma, the most common type of anal cancer, forms in the outer layer of anus tissue.
- Adenocarcinoma begins in the glands that help keep the anus moist, which are located just beneath the outer surface.
- Basal cell carcinoma occurs in deeper layers of anus tissue.
- Cloacogenic carcinoma develops in the part of the anus that’s farthest from the external opening.
Anal cancer symptoms include:
- Abnormal discharge
- Changes in the appearance of your stool, such as narrow stools
- Bleeding or itching near the anus
- Lump in the opening of your anus, which may feel like hemorrhoids
- Pain or pressure near the anus
We start by talking with you about your symptoms and performing a physical exam. Doctors may use a gloved, lubricated finger or short tube with a light at the tip (anoscope) to examine the anus. If we detect a suspicious growth, we may recommend an imaging scan or a procedure to take a tissue sample (biopsy) to further evaluate it. Read more about diagnosing cancer.
Getting the HPV vaccination can lower your risk of anal cancer. Talk to your primary care doctor about your risks and whether the HPV vaccine is right for you. Find out more about cancer prevention.
At Mays Cancer Center, you have access to the full range of treatments, including those that are among the most advanced. Find out more about cancer treatments.
- For early-stage anal cancers, you may receive a combination of cancer drugs (chemotherapy) and radiation therapy. Doctors work together in meetings called tumor boards to coordinate the treatments and services that are right for you.
- Larger anal cancers and ones that spread to other areas often require surgery. Our team includes colorectal surgeons who specialize in procedures that deliver precise care with fewer complications.
Cancer treatment can bring uncomfortable symptoms. You can receive additional therapies, including pain management and emotional support, to help keep your care moving forward. Learn more about our supportive cancer care clinic.
