What conditions can necessitate cesarean section?

There are multiple reasons that deliveries occur by cesarean section.  Some are related to positioning of the baby (breech or other unusual presentations), fetal size, developing infections, failure to progress in labor, and apparent fetal intolerance to labor.  Also, most hospitals feel that if you have had a cesarean section in the past, or any significant surgery involving the uterus, you will need to deliver by cesarean section.
