A cancer patient's pre-op routine is generating a whole lot of buzz.

Dr. Deb Cohan was minutes away from a double mastectomy when she started getting down in the OR.

I was more nervous about how the flash mob was gonna go than how surgery was gonna go, Cohan said.

Cohan is an OB-GYN who convinced most of her surgical team to join her dancy party.

The song? Beyonce's Get Me Bodied.

Watch the whole dance party:

The YouTube video has garnered over 4 million views and thousands of supportive comments.

Beyonce even posted a link to the video on her Facebook page with the message: Deborah you are awesome.
