Trump’s Chief of Staff Susie Wiles Diagnosed With Breast Cancer

White House Chief of Staff Susie Wiles has been diagnosed with early-stage breast cancer, according to an announcement made by U.S. President Donald Trump.

The disclosure was made on Monday, March 16, 2026, when Trump revealed that Wiles had recently received the diagnosis but would continue performing her duties at the White House while undergoing treatment.

Wiles, 68, confirmed that the cancer was detected at an early stage and said she plans to begin treatment in Washington while remaining actively engaged in her role. Medical experts involved in her care reportedly gave her an excellent prognosis, increasing confidence in a successful recovery.

President Trump praised his top aide’s resilience, describing her as “one of the strongest people” he knows and commending her decision to keep working during treatment.

The health announcement comes at a critical moment for the administration as it manages major geopolitical tensions, including the ongoing conflict involving Iran and other pressing domestic and international issues.

Wiles, a veteran political strategist from Florida, played a central role in Trump’s 2024 presidential comeback campaign and has served as one of the president’s most trusted advisers since taking office as chief of staff in 2025.
