White House Chief of Staff Susie Wiles said a mammogram performed during a routine checkup detected an aggressive form of breast cancer, despite her having no symptoms. She told Fox News Digital she had initially considered postponing the scan because her next annual mammogram was not due for several months.
Wiles said her doctor urged her to proceed because the imaging machine was available and her demanding work schedule could make it difficult to return. The mammogram identified the cancer at an early stage. Wiles said that if she had gone back to work without having the scan, she might not have rescheduled until July, about four months later. She credited her doctor’s insistence with helping uncover the disease sooner.
Public reports cited in the source say Wiles was diagnosed in March 2026 and underwent six months of treatment. On Sept. 16, she wrote on X that her pathology results from Mayo Clinic were clear and said she was cancer-free. The account does not provide further medical details about her diagnosis or treatment.
Wiles said the diagnosis came as a shock because she felt well and continued working every day. She also described the psychological strain of treatment, including the recurring anticipation of appointments and test results. She called cancer a difficult and consuming experience, while cautioning against minimizing its impact.
She credited doctors and nurses, along with family, friends and colleagues, for supporting her during treatment. Wiles also said her faith helped sustain her. Continuing to work, she said, gave her a focus beyond the illness and reinforced her sense that cancer was something she was experiencing, rather than the whole of her identity.
Now cancer-free, Wiles said she is paying closer attention to habits such as diet, sleep and exercise, while following her doctors’ recommendations. She encouraged people not to put off routine medical appointments and screenings, saying it is easy to prioritize family and work over personal health. Her account is a personal experience and does not establish medical guidance about screening schedules or treatment.
For people undergoing cancer treatment, Wiles said accepting help and relying on loved ones and medical professionals can matter. She added that people may have difficult days, and that getting through them can itself be meaningful. Her experience, she said, has deepened her appreciation for ordinary days, while leaving her grateful for her work and family and determined to live fully.
