Olympic gold medalist Dorothy Hamill is undergoing treatment for breast cancer, she announced Friday, at The Johns Hopkins Kimmel Cancer Center in Baltimore, Maryland.

The Olympic champion, now 51, said the prognosis is very favorable, reports Reuters, however she will need to take time off from her “Broadway on Ice” tour while she receives treatment.

Hamill was only 19 in 1976 when she won the gold medal at the Olympics. After winning the 1976 world championships she turned professional. She joined the Ice Capades in 1977, and headlined that tour for eight years.

She is one of only seven American women to have won the Olympic gold medal and has been inducted into both the U.S. and World Figure Skating halls of fame.

Hamill said Friday she intends to rejoin the “Broadway on Ice” tour in Fort Lauderdale, Florida, in mid-January.

According to the Associated Press, Olympic gold medalist Brian Boitano, a good friend of Hamill's, will fill in for her, beginning Saturday night in Sarasota, Fla.

Hamill told the Baltimore Sun in a telephone interview Friday evening that she was trying to take things easy.

“I'm OK,” she told the paper. “I’m still a little woozy. It's been kind of a hit in the head. I'll be up to normal things soon, but I've got to take it easy right now.”

According to media reports, other Olympic champions have fought cancer before Hamill: Peggy Fleming, the 1968 Olympic gold medalist, was diagnosed with breast cancer in 1998, but recovered fully, while Scott Hamilton, the 1984 men's champion, was treated for testicular cancer in 1997.
