Undergoing a double mastectomy can be a scary experience. Yet for one woman, her surgery became a much more upbeat occasion.

Breast cancer patient Deborah Cohan checked into Mount Zion Hospital in San Francisco on Wednesday to have both of her breasts removed. But before she went under the knife, she hosted a dance party with her team of doctors.

In a now viral video, Cohan and her doctors can be seen smiling as they dance to Beyonce’s “Get Me Bodied” in the operating room.

Oh her CaringBridge site, Cohan also asked family and friends to organize their own dance party flash mobs in the hallway of her hospital room the day after her surgery.

“I have visions of nurses, patients, my community members (and maybe a few surgery residents) transforming the solemn space of a hospital into a vibrant healing ward,” she wrote.

Several other videos of Cohan’s family and friends dancing in the halls of Mount Zion have been posted to YouTube. On her site, Cohan even encouraged people she did not know to send her pictures or videos of themselves dancing, so that she could make a dancing montage.

“Nothing brings me greater joy than catalyzing others to dance, move, be in their bodies,” she wrote.
