Olympic ice-skating champ Dorothy Hamill is undergoing treatment for breast cancer at Johns Hopkins Kimmel Cancer Center in Baltimore, Md.
A rep for Hamill, 51, calls her prognosis very favorable, but says the treatments will require the Olympic gold-medal winner to take time off from headlining the Broadway on Ice national tour, Access Hollywood reports.
Hamill hopes to rejoin the tour on Jan. 16 in Ft. Lauderdale.
