I'll go one step further than our poster, the leading cause of adult female depression is directly linked to guilt and shame over having once been "pro-choice". In my busy twenty year practice, I see it about three times a month. Women in serious need of mental health counseling for sure!
I recently took a course in preparation for working at a pro-life facility. The instructors mentioned several times that women suffer greatly from mental anguish often times for decades. They had even seen women come in for counseling in their eighties still grieving for the children they had aborted. Two of the women in the class had had multiple abortions. It was painful to see the pain that they still deal with daily even though their abortions were many years ago. My point is, whether abortions have a link to breast cancer or not, they caused unimaginable heartache to the women who have them. Abortion is NEVER THE RIGHT ANSWER.
