This undated handout photo provided by the Moore family shows retired Pittsburgh oncology nurse Pearl Moore, right, with her daughter Cheryl. Pearl Moore's experience watching her mother's painful cancer death persuaded her to make her own living will, and give a copy to her daughter, while she is still healthy. New guidance to cancer doctors says they need to be more candid with advanced cancer patients about when it's time for that kind of end-of-life planning, so they can better choose how to spend their remaining time.
