Brandi Glanville**'s cancer scare turned out to be just that.

The Real Housewives of Beverly Hills star, 40, will undergo surgery on Dec. 12 for the removal of a benign breast tumor, her rep confirms to Us Weekly.

Glanville first made reference to the upcoming procedure via Twitter last week. "I think I found a name 4 tumor in my booby thats coming out dec12 starts with an R &ends with an online," she cracked in an apparent nod to her foe LeAnn Rimes. "It's not the big C, please don't worry," she assured her followers. "It's just some n'lame thats been making me ill."

The jibe at country singer Rimes -- second wife to Glanville's ex-husband Eddie Cibrian** -- came before Glanville called a truce in an exclusive statement to Us.

"My intention has always been to take care of my children and tend to their well-being," Glanville told Us of her sons Mason, 9, and Jake, 5. "Unfortunately, my ex-husband has not been communicative with me in this regard, and so I have needed to seek him out publicly."

In an earlier interview with Us Weekly's Rebecca Bienstock, Glanville claimed that Mason became ill after eating his stepmother's laxatives, mistaking them for candy; Rimes and Cibrian denied the claim.
