The earth isn’t flat?
What if everything we thought we knew about endometriosis and its impact on women is wrong? While this is unlikely, it is not far fetched. Back in the early 1980s, endometriosis was thought to be a disease that primarily affected upper class Caucasian women in their late 30s and 40s. Why did we believe this was true? Because, at that time, these were the majority of women who had access to laparoscopic surgery. Diagnostic and operative laparoscopy is currently the standard of care, so we now understand the disease affects girls as young as teenagers and women of all races and socio-economic backgrounds equally.
