Sunday, November 25, 2007 EDITOR'S NOTE: This is the first day of a seven-day series about the cost of immigration. When doctors swear the Hippocratic oath, they pledge to do all in their power to help their patients. But medical care is extremely expensive today, and hospitals run on money, not ideals. Balancing the ideals with financial reality is an ongoing struggle for medical professionals, and the number of illegal immigrants seeking medical treatment they can't afford exemplifies the problem.
