Jennifer Lopez has promised to fight for a young Hispanic mother's life because she fears her plight could just as easily be her own one day. The Latina singer/actress is working to find a donor for bone cancer sufferer JANET ORVELLES - whose only chance for survival is a bone marrow transplant. However, the worldwide pool of Hispanic donors is currently limited to just under 10 million people. Lopez says, "I just kept thinking I could be the one in need of a donor and I would have to reach out to the Hispanic community. "These things just make you realise that we are all interconnected, and depend on one another."
