The elegant Bueno, South America's most successful player, shot to global fame when she claimed her maiden grand slam at Wimbledon in 1959 and her second at the U.S. Nationals two months later, Reuters reports.
She successfully defended her Wimbledon crown the following year and claimed back-to-back U.S. Nationals titles in 1963-64.
She also reached the final of the 1964 French Championships and the 1965 Australian Championships, but lost to Margaret Court at Roland Garros and retired hurt against the Australian great at Kooyong.
Bueno was also a prolific doubles player, claiming women's titles at all four of the grand slams from 1958-68 and a mixed doubles championship at Roland Garros in 1960.
The 9 de Julho Hospital said she had been admitted for "oncological treatment" and asked for privacy.
