The event will offer boxing matches, opportunities to learn how to prevent contracting cancer and help raise money to support three non-profits - two of them involved in the fight against the disease.
The event will begin at 2 p.m. Friday at Finish Line Sports Grill, 2201 N. White Ave., with a weigh-in, a celebrity autograph session, live entertainment and starting at 7 p.m. a 14-match amateur boxing card.
On Saturday, doors open at 2 p.m. Activities include autograph sessions, a question-and-answer session with a panel of trainers and celebrities, live performers including one by hip-hop artist Medusa and several professional boxing matches starting at 6 p.m.
The evening's main event is a match between Kaleisha "Wild Wild" West and Christina "The Bullet" Ruiz.
Those expected at Saturday's activities include "Sugar" Shane Mosley, Sugar Ray Leonard, Andre Ward, Henry Tillman, Mia St. John, Israel Vasquez and Kareem Rush.
The event is being organized by the Diamonds Love Foundation, a non-profit founded by the family of Mosley, a retired champion boxer.
The Mosleys were inspired to organize the event after coming in contact with many people, including friends and relatives, affected by different types of cancer, some of whom died, said Cerena Mosley-Prude, the foundation's chief executive officer and Mosley's older sister.
Among those who have died as a result of the disease are boxers Joe Frazier and Genaro "Chicanito" Hernandez.
Shane Mosley worked with Hernandez, sparring with him as a young athlete, his sister said.
As a result, "we decided to do the first KO cancer event," Mosley-Prude said.
Some statistics indicate one out of four people will be diagnosed with the disease, she said.
That means "somebody is going to be affected," Mosley-Prude said.
"Boxing for a Cure" is "about bringing awareness.... Don't let this creep up on you," she said.
Diamonds Love Foundation is working with the Susan G. Komen Foundation and the American Cancer Society on the event and will share proceeds with both organizations.
Part of the proceeds will go to the Diamonds Love Foundation, which supports education, health, mental health, fitness and youth programs.
Representatives from the Susan G. Komen Los Angeles County affiliate will be at Saturday's activities, said Lisa Campbell, the affiliate's manager.
Volunteers with the American Cancer Society will also be present Saturday, providing guests information on free cancer-prevention programs and services and "where to turn after they've been diagnosed with cancer," said Eric Beikmann, spokesman for the American Cancer Society Los Angeles Region.
