Aa.

AA is the first name for an international cancer control program, proposed in the 1950s by the National Association for Cancer Research and its part, the Commission on Education (then called the Commission on Cancer Treatment Information). The Commission decided to perpetuate the name “AA” due to its sound similarity to an abbreviation (for example, AA - combating alcohol addiction).

“AA” stands for variously: “American Association”, “Arc of Angels”, “Administration Certification” (AA - “Administration by the Administered”), or the word “aa” itself can be translated as “attacking” ", or "we want to help."
