What is endometriosis?
Endometrial tissue consists of glands, blood cells, and connective tissue. It normally grows in the uterus, to prepare the lining of the womb for ovulation.
Endometriosis is when cells from the lining of the uterus grow and implant outside of the uterus. This can occur in many different locations, but most commonly is found near the fallopian tubes, ovaries, or in the pelvis.
