Susie Wiles, the first woman to serve as White House chief of staff, has been diagnosed with early-stage breast cancer but will continue working ‌while undergoing treatment, U.S. President Donald Trump said on Monday.

Wiles, 68, has been a constant presence at Trump's side since he returned to office in January 2025. Republicans have credited her ​with bringing greater discipline to the White ​House during Trump's second term while allowing the president to operate largely on his own terms.

"Her strength and her ​commitment to continue doing the job she loves, and does ⁠so well, while ⁠undergoing treatment, tells you everything you ‌need to know about her," Trump said in a Truth Social post, adding that her prognosis was excellent.

Trump said Wiles had decided to begin treatment immediately and would be "spending ⁠virtually full time at the White House" during that period.

Moments after announcing her diagnosis, Trump appeared alongside Wiles at a White House event in the ‌East Room, holding her chair for her as she sat beside him. Wearing a pink jacket, Wiles received hugs from several attendees as she entered the room.

Wiles managed Trump's comeback 2024 ​campaign and is regarded as one of his most important political advisers.

In a statement, Wiles ⁠said she was grateful the cancer was detected early.

"Nearly one in eight ⁠women in the United States will face this diagnosis," Wiles said. "Every ⁠day, ⁠these women continue to raise ​their families, go to work and serve their communities with strength and ​determination. I now ⁠join their ranks."

"I am encouraged by a strong prognosis,” she said. "I am also deeply thankful for the support and encouragement of President Trump as I undergo treatment and continue serving in my current role."
