Number of New Cases and Deaths per 100,000: The number of new cases of anal cancer was 1.8 per 100,000 men and women per year. The number of deaths was 0.2 per 100,000 men and women per year. These rates are age-adjusted and based on 2007-2011 cases and deaths.

Lifetime Risk of Developing Cancer: Approximately 0.2 percent of men and women will be diagnosed with anal cancer at some point during their lifetime, based on 2009-2011 data.

Survival StatisticsShow More

How Many People Survive 5 Years Or More after Being Diagnosed with Anal Cancer?

Relative survivalExternal Web Site Policy statistics compare the survival of patients diagnosed with cancer with the survival of people in the general population who are the same age, race, and sex and who have not been diagnosed with cancer. Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. No two patients are entirely alike, and treatment and responses to treatment can vary greatly.

Based on data from SEER 18 2004-2010. Gray figures represent those who have died from anal cancer. Green figures represent those who have survived 5 years or more.

Additional Information

Cancer stage at diagnosis, which refers to extent of a cancer in the body, determines treatment options and has a strong influence on the length of survival. In general, if the cancer is found only in the part of the body where it started it is localized (sometimes referred to as stage 1). If it has spread to a different part of the body, the stage is regional or distant. The earlier anal cancer is caught, the better chance a person has of surviving five years after being diagnosed. For anal cancer, 48.5% are diagnosed at the local stage. The 5-year survival for localized anal cancer is 79.7%.

Anal cancer represents 0.4% of all new cancer cases in the U.S.

0.4%

In 2014, it is estimated that there will be 7,210 new cases of anal cancer and an estimated 950 people will die of this disease.

Anal cancer is slightly more common in women than men. Infection with human papillomavirus (HPV) has been associated with this cancer. The number of new cases of anal cancer was 1.8 per 100,000 men and women per year based on 2007-2011 cases.

Percent of New Cases by Age Group: Anal Cancer
0.0% under 20; 1.1% 20-34; 7.3% 35-44; 25.2% 45-54; 27.6% 55-64; 18.7% 65-74; 13.9% 75-84; 6.2% 85 and older

Anal cancer is most frequently diagnosed among people aged 55-64.

Trends in RatesShow More

Changes Over Time

Keeping track of the number of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.

Using statistical models for analysis, rates for new anal cancer cases have been rising on average 2.2% each year over the last 10 years. Death rates have been rising on average 3.7% each year over 2002-2011. 5-year survival trends are shown below the figure.

Cancer and the Anus

Gastrointestinal (digestive) system anatomy; shows esophagus, liver, stomach, colon, small intestine, rectum, and anus.

Anal cancer is a disease in which malignant (cancer) cells form in the tissues of the anus at the end of the large intestine, below the rectum. The anus is formed partly from the outer, skin layers of the body and partly from the intestine.

The statistics presented in this factsheet are based on the most recent data available, most of which can be found in the SEER Cancer Statistics Review. In some cases, different year spans may be used. Estimates for the current year are based on past data.

Cancer is a complex topic. There is a wide range of information available. This factsheet does not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although it provides links to information in many of these areas.
