Giuliana Rancic, a personality on the entertainment network E!, has canceled her Monday appearance on campus, citing medical concerns.

Rancic was scheduled to appear at 7 p.m. Monday in the Ohio Union Performance Hall. The event was to be a collaboration between the Ohio Union Activities Board and Scarlet, Gray, & Pink: A Walk for Stefanie Spielman.

OUAB announced the show was canceled Saturday and also said it is working to reschedule.

“Thank u:) SO sad but I’m rescheduling w @OUAB,” Rancic tweeted Saturday from her account, @GiulianaRancic, in response to a tweet wishing her to feel better.

Rancic, 37, is an anchor on E!’s “E! News,” alongside Ryan Seacrest. Rancic announced in October she had early stage breast cancer, for which she later underwent a double mastectomy.

Rancic has been featured in “Malibu’s Most Wanted” in 2003 and “Fantastic Four: Rise of the Silver Surfer” in 2007. She also stars in her own reality show, “Giuliana and Bill,” with her husband Bill Rancic, which is currently airing on the Style Network, and “Fashion Police,” which airs on E!

She appeared in “People’s” 100 Most Beautiful of 2006 issue and “Maxim’s” Hot 100 Women list of 2004.
