(CNN) -- One of the truly remarkable, and relatively recent, boosts to the health of poor women in this country has been their opportunity to get preventive, reproductive health services, at little or no cost, in one place.
    Over the years, one Planned Parenthood clinic after another has been able to offer these women not only affordable contraception, but full exams that include screening for breast cancer, the No. 1 cancer killer of women.
