There’s really no better medicine than dance. Just ask Deborah Cohan, who waged an all-out flash mob in her operating room right before a double mastectomy. Cohan, an OB-GYN and mother of two, figured the best way to prep for surgery was breaking it down Beyonce-style with her entire surgical team at Mount Zion Hospital in San Francisco, California. But she doesn’t want to be the only one dancing. Cohan asked on her CaringBridge page that others send dancing videos to her, in hopes she could have an entire “healing video montage” to watch post-op.
