Posted March 10, 200817 yr RIHANNA, 20, has helped save the life of a leukaemia patient. The Umbrella singer was so moved by mother-of-two Lisa Gershowitz Flynn's story she joined forces with DKMS, the world's leading bone marrow donor centre, to find her a match. The 41-year-old lawyer was diagnosed with acute myelogenous leukaemia, a fast-growing cancer of the blood and bone marrow last November, and was given just four to six weeks to find a donor. Following Rihanna's public plea for help, 5000 potential donors contacted DKMS and a match has now been found. - BANG Showbiz / AP http://www.news.com.au/common/imagedata/0,,5929576,00.jpg
