Being the daughter of divorced and poor parents Cacilda could not establish friendships with people of high society, and instead began to frequent the bohemians and avant-garde circles in the city.
That year, Nydia Lycia turned down a role in the play "Mulher do Próximo" (Women's Next) by Abilio Pereira de Almeida, produced by the Brazilian Comedy Theater (TBC) to not have to kiss or say "lover" in the scene, because this could cost you employment at a major store.
Cacilda, who replaced her, demanded to be hired as a professional, ending the old prejudice that serious artist should be dilettante In 30 years of career, Cacilda performed in 68 plays staged in Rio de Janeiro and São Paulo; made two films ("Luz dos Seus Olhos" - Light in Their Eyes - in 1947 and in "Floradas na Serra" - Sierra Blossoms - in 1954) and a soap opera ("Ciúmes" - Jealousy, 1966).
On TV Tupi besides participating in teleteatros, Cacilda inaugurated the Teatro Municipal de São Carlos with the play Waiting for Godot in early 1969.
Cacilda suffered a stroke on 6 May 1969 in São Paulo during a performance of the play Waiting for Godot, staged with her husband Walmor Chagas.
