Democratic presidential candidate and former North Carolina senator John Edwards missed an Iowa campaign event on Tuesday so he could be with his wife as she prepared for a medical appointment the following morning.Elizabeth Edwards, diagnosed with breast cancer just before the 2004 election, when her husband ran for vice president, has survived chemotherapy, surgery, and radiation and has written a book -- Saving Graces -- about her entire journey.
Edwards' campaign crew has insisted Wednesday's appointment was a routine follow-up to a medical visit his wife had the day before and that Elizabeth Edwards, 57, has been living cancer-free.
Today at noon, Edwards will hold a press conference about his wife's health and how it may -- or may not -- affect his candidacy.
