The mom of two, clad in a hospital gown, boogies down to Beyonce's "Get Bodied" for about six minutes before her surgery at Mt. Zion hospital in San Francisco, as captured in the YouTube clip.
On her CaringBridge page, Cohan invited others to participate in a virtual flash mob by sending footage of themselves dancing to the track, from Beyonce's 2006 album B'Day.
"I have visions of a healing video montage," Cohan wrote on Nov. 1. "Nothing brings me greater joy than catalyzing others to dance, move, be in their bodies. Are you with me people?"
Don't just watch – get up and dance – along to the uplifting video below.
