Risk of uterine rupture during labor higher for women with a prior cesarean delivery
...ew England Journal of Medicine. The study involved analyzing the records of 20,095 women who had their first child delivered by cesarean section and who delivered a second child either by cesarean or following labor. These records were from 1987 through 1996 and came from civilian hospitals in Washington Sta...... Today that explanation was dashed as scientists analyzing the combined data also concluded that neither exposure explains the high rates of breast cancer in the U.S. Northeast.
