TMC is an acronym which stands for Traditional Male Circumcision. This refers to circumcision practicing in tribal communities like e.g. in Africa or Australia.
There are many acronyms and abbreviations for female and male genital mutilation. The acronyms TMC and MMC stand for a distinction between the techniques used. While MMC is supposed to experience an appreciation through the integration of the term "medical", the "traditional" in TMC means that this is definitely the worse method.
