Fibroids or leiomyoma are benign muscle tumors of the uterus
present in many woman.
The smaller fibroids <3cm pose no risk. Larger fibroids may be problematic in that they may grow to significant size (cantelope size) and may obstruct the outlet for the baby. Sometimes a cesarean may be indicated. These are not removed during delivery or cesarean but wait til 6 months after. They can shrink.
