Endometriosis Underlying Cause
The most common sites for endometriosis include:
- Outside surface of the uterus
- Lining of the pelvis
The cause of endometriosis is unknown. However, a number of theories may help explain the growth of endometrial cells outside the uterus.
- Endometrial cells may spread from the uterus, through the fallopian tubes, and into the pelvis, where they attach to the surface of other organs.
- The lymphatic system may carry endometrial cells to other structures inside the pelvis.
- Cells that line other organs inside the pelvis transform into endometrial cells.
