Camillo Arduino turned professional after the 1920 Olympic Games, and rode in the Giro d’Italia and at Milan-San Remo through 1928. He finished the Giro only in 1924, while his best finish at Milan-San Remo was seventh in 1923. As a pro he raced for mostly Italian teams, but changed teams almost yearly, wearing the jersey for Bianchi-Dunlop in 1921, Bianchi-Salga in 1922, Atala in 1923, Maino in 1924 and 1927, and Maino-Dunlop in 1928, although he briefly raced for the French team, Alcyon-Dunlop in 1928.
