Dying GP urges new law on assisted suicide A best-selling GP author who is dying from cancer has made an impassioned plea for a rethink on assisted suicide. Dr Ann McPherson is the GP behind the million-selling book Diary of a Teenage Health Freak and the DIPEx patient support charity. She is also terminally ill with advanced pancreatic cancer, and believes people suffering as she is must be given the option of an assisted death.
