Susie Wiles says she is cancer-free after biopsy

Wiles announces clear results

White House chief of staff Susie Wiles said on Wednesday, Sept. 16, that she is cancer-free after undergoing a medical procedure at the Mayo Clinic earlier in the week.

Wiles was diagnosed with breast cancer in March. She wrote on X that she had received clear results and expressed gratitude to her family, friends, doctors and people who supported and prayed for her. She also thanked President Donald Trump.

CBS News first reported that Wiles had undergone the Mayo Clinic procedure. CBS reported that pathology results from a biopsy performed Monday were clear.

Her White House role

Wiles has served as Trump’s chief of staff since his inauguration in 2025. The chief of staff is the president’s top White House aide, helping oversee staff and manage activity around the president.

Wiles has continued appearing alongside Trump since her March diagnosis. She traveled with him to Dallas the week before her announcement but did not accompany him on his more recent weekend trip to Ireland.

Wiles did not connect her absence from the Ireland trip to the procedure in her public statement. Her announcement focused on the biopsy result and thanked those who supported her after the diagnosis.

What comes next

Wiles did not announce any change to her duties as chief of staff. Her statement also did not set out future medical appointments or other steps following the clear pathology results.
