Anal Tumors and Cancers :

There is always a possibility of getting different diseases and after the virus has penetrated in the body, there is no way humans can get rid of it soon. Anal opening is a vulnerable part of the human body. Any minor scratch or bruise caused due to any reason can give birth to any severity. At times these abnormal lumps, swellings etc can cause cancerous cells to develop within that specific area.

 Many types of tumors can develop in the anus. Some of these tumors are benign (non-cancerous). Others are cancerous, which means they can grow into and damage nearby tissues and can spread to other parts of the body. There are also some growths that start off as benign but over time can develop into cancer. These are called pre-cancerous conditions. This section discusses all of these types of abnormal growths.  

Anal cancer in the simplest definition is a disease which is caused in the anus when cancer cells form in the tissues of the anus.

 Normally, cells in the body will grow and divide to replace old or damaged cells in the body. This growth is highly regulated, and once enough cells are produced to replace the old ones, normal cells will stop dividing. Tumors occur when there is an error in this regulation and cells continue to grow uncontrolled. Tumors can either be benign or malignant. Although benign tumors grow uncontrolled, then do not break off and spread beyond where they started and do not invade into surrounding tissues. Malignant tumors, however, will grow uncontrolled in such a way that they invade and damage other tissues around them. They also gain the ability to break off from where they started and spread to other parts of the body, usually through the blood stream or through the lymphatic system where the lymph nodes are located. Over time, the cells within a malignant tumor become more abnormal and appear less like normal cells. There is often a change in the development of the cells in the human body. These changes become apparent after a very long time, when they have become infected. The cancer cells are changeable and they tend to change unknowingly. These cells are hard to detect because they have the ability to merge themselves with the other cells of the body.
