Bedrest is often indicated to reduce pressure on the cervix. Once the cervix has been sutured, delivery of the baby may be done by cesarean section. Fibroid Tumors Explanation Non-cancerous tumors develop within the walls of the uterus. These common growths can interfere with implantation of a fertilized egg and cause spontaneous abortions. Symptoms Usually none.
Large tumors can cause pain and frequent menstrual bleeding.
Treatment Microsurgery and laser surgery are used to remove tumors. Severe cases may require hysterectomy. Rarely a female baby is born without a uterus. Other developmental defects include a heart-shaped uterus that has a septum that partially divides the uterus into two compartments. If the compartment is too small to expand during a full term pregnancy, then the pregnancy can end in a miscarriage.
