Not an organization in the conventional sense of the word as there are no fees or dues whatsoever. The only requirement for membership is an honest desire to stop drinking. AA is not allied with any particular faith, sect, or denomination, nor do they oppose any. AA simply wishes to be helpful to those who are afflicted with the alcoholism.

Cancer is the common term for tumors (neoplasms) characterized by uncontrolled growth. Unlike normal cells, cancer cells are atypical in structure and do not have specialized functions. They compete with normal cells for nutrients, eventually killing normal tissue. Cancerous, or malignant, tissue can remain localized, invading only neighboring tissue, or can spread to other tissues or organs via the lymphatic system or blood; virtually all tissues and organs are susceptible.
The branch of medicine concerned with diagnosis, treatment, and research into the causes of cancer is oncology.
