Betty Ford says one of the toughest aspects of enduring cancer was facing the stares at a White House formal gathering following her mastectomy.
Mrs. Ford, 79, openly discussed her breast cancer in the mid-1970s, when few women were as willing to be so candid about it.
Asked during an interview with CBS' "60 Minutes" whether that took guts, Mrs. Ford said: "Well, it was gutsy the first time I appeared at a state dinner and I walked down those stairs and I just knew all eyes were upon me.
"And they were probably saying, 'Which one did they say it was?' "
In the interview, which was scheduled to air Sunday, Mrs. Ford also discussed her alcoholism and the rehabilitation center that she founded to help alcoholics and other addicts.
