Is cesarean scar pregnancy a type of ectopic pregnancy?

　　Ectopic pregnancy usually refers to a pregnancy occurring outside the uterine cavity. In general, cesarean scar pregnancy is not considered a type of ectopic pregnancy. If any physical discomfort occurs, it is recommended to seek medical attention promptly and receive treatment under the guidance of a qualified physician. Specific analysis is as follows:

　　Cesarean scar pregnancy refers to the implantation of a fertilized egg in the previous cesarean section scar on the uterus. This condition typically occurs in women with a history of cesarean delivery. Due to the different tissue structure at the scar site compared to normal uterine wall, implantation here increases the risk of serious complications such as placenta accreta and massive hemorrhage. Ectopic pregnancy, on the other hand, refers to implantation of the fertilized egg outside the uterine cavity—commonly in locations such as the fallopian tubes, ovaries, or abdominal cavity. Ectopic pregnancies are abnormal and cannot receive sufficient nutrients and support in these locations, making them prone to embryonic arrest, miscarriage, or rupture with internal bleeding. Therefore, there are clear distinctions between the two conditions.

　　To ensure maternal and fetal safety, if either cesarean scar pregnancy or ectopic pregnancy is suspected, prompt medical evaluation by a qualified healthcare provider is essential. Early ultrasound examination during pregnancy can help detect these conditions early, allowing timely and appropriate interventions.
