Model and TV host Janice Dickinson has revealed that she's got breast cancer and vows to battle the disease.

"Janice is going to fight and she will not let this diagnosis define her. She wants to encourage all women to have regular checkups, as that is how her cancer was discovered," said Dickinson's attorney, Lisa Bloom.

Dickinson told the Daily Mail of London that a "pea-size" lump was found on her right breast during a doctor visit on March 8. Three days after the lump was discovered, Janice had a mammogram and a biopsy. She will undergo surgery and radiation therapy.

Dickinson, author of "No Lifeguard on Duty: The Accidental Life of the World's First Supermodel," was a cast member of "The Surreal Life" and "America's Next Top Model."
