If this pregnancy ends in a cesarean

One decision that reaches years forward.

About one birth in three in the United States is a cesarean, and a first cesarean is usually followed by more. Only about 15% of American women with a previous cesarean give birth vaginally afterward.

That matters because the risks compound. In a study of 30,132 cesareans, the risk of placenta accreta, a condition where the placenta grows into the uterine wall and often costs a woman her uterus, was 0.24% at a first cesarean, 0.57% at a third and 2.13% at a fourth. Hysterectomy risk followed the same curve.
