I learned this lesson from my patients.
I hope I can continue educating about non-invasive imaging for #endometriosis, which includes what to do when the imaging is negative.

"A hysterectomy or the removal of a uterus is not at all a treatment for endometriosis." — @MathewLeonardi (@machealthsci) tells Nam why the common surgery is still recommended by doctors. Listen to (Mis)Treated: youtube.com/watch?v=AvOPD-M5… | Producers: @namshine & @MatthewOMara
An interview with @tvo?! How cool is it that @ShyTheEndoGuy Freger and I were interviewed by @namshine Nam Kiwanuka for a new TVO series called (MIS)Treated which explores how medicine has – and still is – failing women and speaks to the people looking to make a difference.
“Endometriosis behaves very much like a cancer.” Why does it take 5–7 years to diagnose in Canada, leaving endometriosis sufferers in pain? @MathewLeonardi (@McMasterOBGYN) talks with @namshine on the next episode of (MIS)Treated. podcasts.apple.com/ca/podcas… | Producer: @MatthewOMara

@ShyTheEndoGuy, who is completing his work in gynecologic surgeon and sonologist in @MathewLeonardi's lab recently wrote about endometriosis and questions why there is no national strategy developed for the crisis in Canada.

And as always, inspired by a recent controversial question I was asked! What should we make of the scenario of the “clinical diagnosis” without any investigations specific to endometriosis?
