Though New Canaan High School juniors Eva Alexander, Sienna de Kanter and Mairead Greiner all joined the NCHS Students Against Cancer Club last fall for individual reasons, they share a deeply important motivation: Each of the teens has loved ones whose lives have been altered by or lost to the disease. Eva Alexander’s father, Sloan Alexander, had surgery last March following discovery of a sarcoma, and is now undergoing chemotherapy. De Kanter’s grandmother, Linda Glenn, died last March following a battle with colon cancer. And Greiner, whose grandfather Joseph Casey is a two-time cancer survivor (colon and prostate), has two grandmothers currently fighting skin cancer. Through the club, the students found out about the “Student Visionaries of the Year” program run by Blood Cancer United, a nonprofit organization that seeks to rid the world of blood cancer.
