Belinda Emmett knows hospitals. Starring in Channel 7`s All Saints, she came to know every nook and cranny of St Vincent`s Hospital in Sydney, and she learned first-hand the trials of being patient when she had surgery for breast cancer in 1998. So she was the perfect person to cheer up Cassandra Stewert, who has a kidney condition, at the Royal Children`s Hospital yesterday ( 11.04.01). Emmett says she can`t wait to appear on the panel for the Good Friday Appeal.
