LISA RAY: The 'Water' actress is one of the most well-known crusaders for cancer awareness today. In 2009, she was diagnosed with the rare multiple myeloma (cancer of the white blood cells which destroys the bone marrow). In her blog, The Yellow Diaries, she posted details of her treatment and pictures of her hair shaven off. In 2010, after a successful stem cell transplant, Lisa announced that she was cancer-free. She champions the cause of the little-known disease, for which she helped raise funds for its research. In one of her many unique campaigns, she chronicled her life, love, and cancer experiences through sarees. The ‘Ray of Hope’ collection can be either draped as a sari or can be used as artwork. Ray is not completely cured of the disease as it is incurable and maintains a very healthy diet and lifestyle. (File Photo)
