White House chief of staff Susie Wiles has announced that she is now cancer-free after being diagnosed with breast cancer in March. She shared the news on X, stating that after a medical appointment at the Mayo Clinic this week, her pathology results came back clear. Wiles, 69, has served as President Donald Trump's White House chief of staff since the start of his second term. She thanked Trump for his "unwavering support" and expressed gratitude for the opportunity to continue advancing his "America First Agenda." Wiles was diagnosed with breast cancer in March, and the condition was detected in its early stages, giving her a "strong prognosis." She first announced her diagnosis in mid-March, noting that about one in eight women are diagnosed with breast cancer each year. She emphasized that many women continue to work and care for their families while undergoing treatment, and she planned to do the same. "Every day, these women continue to raise their families, go to work, and serve their communities with strength and determination," Wiles said in her March statement. "I now join their ranks." President Trump had previously commented on Wiles' diagnosis, stating that she had a "fantastic medical team" and had been given an "excellent prognosis." He first shared the news on his social media platform, Truth Social, before Wiles released her own update about her health. Trump noted that Wiles would be "spending virtually full time at the White House," and praised her for continuing her work while undergoing treatment. He described her as a "tough" and "deeply committed" advisor who would soon be "better than ever." Wiles had a medical procedure related to her breast cancer diagnosis at the Mayo Clinic earlier this week, according to multiple sources. She returned to work shortly after, conducting White House business, making phone calls, and running meetings, the sources said. White House spokespersons did not immediately explain the reason for her visit to the clinic, which was located outside Washington, D.C. Wiles recently traveled with the president to Dallas for the Republican midterm convention, as noted in an Air Force One manifest provided by the White House. She did not accompany him on his recent trip to Ireland. A Florida native, Wiles has long been involved in political consulting and served as campaign manager for President Trump's 2024 presidential bid. She is the daughter of the late football broadcaster Pat Summerall. According to the American Cancer Society, breast cancer is the most common cancer diagnosed among women in the U.S. and the second-leading cause of cancer-related deaths among women, following lung cancer. The specific type of breast cancer Wiles had has not been disclosed.
