Endometriosis Support Group
Endometriosis is a common medical condition where the tissue lining the uterus is found outside of the uterus, typically affecting other organs in the pelvis. The condition can lead to serious health problems, primarily pain and infertility. A major symptom of endometriosis is pain, mostly in the lower abdomen, lower back, and pelvic area.
I got this off of the CEC in Atlanta's website, maybe this will help explain it a little better. I was confused too so I looked it up too and found this:
Laser ablation, cauterization, and fulguration treat lesions on the surface of the pelvic organs. These techniques are generally discontinued when the visible superficial portion of the endometriosis is no longer recognizable. Unfortunately, this means deeper disease can be left behind to cause more problems. Physicians who believe that endometriosis can never be controlled and will always come back often do this type of surgery.
