Anal cancer statistics is a general pattern followed worldwide to display the number of cases related to anal cancer, their occurrence on the basis of sex, region, personal medical history, etc and the survival rate for various types of anal cancers. Statistics are a result of empirical methods used to interpret the changes taking place in the occurrence and pattern of anal cancer and keep a track of the major concerns related to the disease.

What do we mean by anal cancer statistics?

Anal cancer statistics is a simple way to represent the complexities taking place in the area of anal cancer. Anal cancer is of various types as primary, secondary, squamous and non-squamous. Prime parameters like life expectancy, survival rate, cancer-deaths and prognosis (prognosis of anal cancer) are different for different types of anal cancers.

Statistics for anal cancer uses various mathematical techniques and to sort and represent the data in the simplest form so that it can be interpreted easily without any special studies. Usually, statistics relating to anal cancer is a comparison of two different periods to let the reader know about any major changes that might have taken place in the mean time. In most of the cases, the data is represented in a tabular form to make it more compact and easy to understand.

Statistics are also useful to do a comparative study of an increase or decrease in severity of the cases related to anal cancer. Information provided by the statistics related to anal cancer plays a vital role in research and is quite useful in calculating life expectancy.

Variations used in anal cancer statistics

Statistics related to anal cancer has no universal format and may differ from person to person. Interpreting the collected data in the right manner is very important to make the statistics reliable and transparent. Many organizations have their own formats and parameters to collect data and the statistics are represented accordingly.

Sex is one of the important parameters in representing statistics for anal cancer. The disease is less frequent in males as compared to females and is detected mostly in adults over 45 years of age. Calculating statistics also considers the patients infected by sexually transmitted diseases like human papillomavirus (HPV) and AIDS (Acquired Immune Deficiency Syndrome).

Personal or family history of the disease is also taken into consideration while representing the statistics. Some of the vital factors like the nature and origin of tumors are considered and the cancer cases are represented accordingly. Cancer of the anus is more common in people addicted to smoking, alcoholism and chewing tobacco. Some organizations may come out with their statistical report by taking such habits into consideration if the cases caused due to these habits are considerable.

In some organizations, the statistics are represented taking the living conditions and environment into consideration. It may include some of the uncommon factors like prolonged exposure to radiations, anal sex and frequent infections in the anus into consideration if a high number of people are suffering from the same.

Thus, the statistics takes prime causes and symptoms into consideration before framing the data and tries to cover maximum variations to increase the scope of study.

Anal cancer statistics in numbers

American Cancer Society has come out with some of the vital statistics related to anal cancer. According to it, the disease occurred mostly at the age of 60 years. There were absolutely no cases of anal cancer detected in people below 20 years. Just 1.1% of the overall anal cancer cases occurred in the age group of 20-34 years and 9.4% cases occurred between 35-44 years. 24.7% cases were detected in the people within the age group of 45-54 years and 25% were found in people between 55 and 64 years of age. In the age group of 65-74 years of age, the cases came down to 18% and dipped further to 15.2% in the age group of 75-84 years. Detected cases dipped considerably in the persons aged above 85 years and amounted to just 6.6% of the overall cases.

Survival rate of anal cancer patients has been the best in patients where the tumors were detected in very early stages. Also, the life expectancy of such patients has been the highest. The chances of being prone to the disease increases with age and the tumors are detected less easily in older people. According to the American Cancer Society, the cancerous development in the anus is not a common form of cancer and very few cases are projected to be detected in the coming years.

Many organizations have come up with their own anal cancer statistics and have tried to give new dimensions to anal cancer research. The main reason behind publishing the statistical report is to create awareness about anal cancer and identify the most common causes or symptoms related to the development of cancerous cells in the anus. Statistics can be more reliable if they cover a wide number of variations and do not restrict to a particular form of anal cancer.
