Trump says Susie Wiles' "prognosis is excellent" after breast cancer diagnosis

White House Chief of Staff Susie Wiles disclosed in March that she had been diagnosed with breast cancer, which doctors found early, and began treatment immediately. President Trump publicly supported her, said she would continue working, and gave an upbeat view of her care. Wiles stayed in her post during treatment; in July she visited Capitol Hill to meet Senate Republicans and help break a stall over Trump’s SAVE America Act. She is the first woman to serve as White House chief of staff. On Sept. 16, 2026, Wiles said on X that Mayo Clinic pathology results were clear and she was cancer-free, thanking supporters and Trump. Vice President JD Vance and several lawmakers welcomed the news. The White House declined further comment.
