Figure-skating icon Dorothy Hamill, 51, is being treated for breast cancer at Baltimore’s Johns Hopkins’ Kimmel Cancer Center, according to The Baltimore Sun.

Hamill, who was born in Chicago, left the national touring company of Broadway on Ice and—according to her longtime friend Dean Moye, a production manager for Cirque du Soleil—she decided to publicize her treatment so she could be honest about the reason for her departure.

Hamill, who influenced many girls in the 1970s with her ‘wedge’ haircut, is a three-time U.S. champion who also won the 1976 world championships and captured the gold in the Winter Olympics that same year.
