Ozzy and Sharon Osbourne's 21-year-old daughter Aimee has had a lump removed from her breast in Los Angeles, the Daily Mail reported Wednesday.

The former Black Sabbath frontman and his wife flew to Los Angeles from London Friday when doctors advised their daughter a potenitally cancerous lump had to be removed.

Sharon Osbourne, who herself only recently recovered from colon cancer, issued a statement thanking fans of the well-publicized family for their support of daughter Aimee.

"The operation went very well on the whole but there have been a few minor complications and she will be having more treatment and lots of rest over the next few weeks," the statement said. "We're sure she'll make a complete recovery.

Aimee was the only Osbourne not to appear in the MTV show that propelled the family to worldwide stardom.
