Endometriosis

Make it clearer

In endometriosis, tissue similar to the endometrium, the lining on the inside of the uterus, grows somewhere outside the uterus. Similar, not identical, and that word matters. Wherever this tissue settles, it sets off inflammation and scarring: the area gets irritated and, over time, ends up marked, the same way skin stays marked after a wound that took a long time to close.

Most of the time that tissue sits in the pelvis, the region that houses the uterus. But that is not the only place it can turn up: it can also appear in other areas, among them the abdomen and the chest.

In brief

In endometriosis, tissue similar to the endometrium grows outside the uterus and causes inflammation and scarring.

It usually sits in the pelvis, but it can also show up in other areas, including the abdomen and the chest.
