Professional
In October, Bessala started his professional career with a victory, where he defeated the Belgium's Jean-Pierre Heirmann with a first-round technical knockout. Six victories, one draw, and yet another five victories followed. In November 1974, the last victory over Eddie Blay from Ghana, who had won the bronze medal in the class of super lightweight in 1964, gained Bessala the African title in the welterweight class. The title was taken from him by Salem Ouedraogo from the Côte d'Ivoire in January 1976. After a longer break, Bessala gained back the African title from his fellow countryman, Bechir Boundka in June 1978. He aimed to defend this title again in his 16th fight, but Mimoun Mohatar from Morocco knocked him out in the 12th round in December 1978. Bessala retired from boxing shortly thereafter.
