Genaro Hernández (May 10, 1966 – June 7, 2011) was a Mexican American professional boxer who competed from 1984 to 1998. He was a two-time super featherweight world champion, having held the WBA title from 1991 to 1995, and the WBC and lineal titles from 1997 to 1998. Additionally, he challenged for the WBO lightweight title in 1995.
After retiring from boxing Hernández was diagnosed with stage four rhabdomyosarcoma of the head and neck, a very rare form of cancer, and one which Hernández' insurance would not cover for treatment. Although Hernández collected several large purses in his career, including $600,000 for his final fight against Mayweather, he was not able to afford his expensive treatments and benefits were held to assist in paying what insurance would not cover. Bob Arum, of Top Rank Promotions, who promoted Hernández, footed Hernandez' bills for chemotherapy for a number of years, until Hernandez died, also having him brought to and from the chemotherapy sessions. In mid 2009 it was reported that Hernández' cancer was in remission but in early 2010 the cancer had returned and Hernández was undergoing treatment.
On June 3, 2011, it was announced that Hernández would stop chemotherapy treatment. Hernández died from cancer on June 7, 2011, at the age of 45. Floyd Mayweather paid for Hernández's funeral expenses.
