White House chief of staff Susie Wiles said Monday that she has been diagnosed with breast cancer, which was detected early, and that she will continue to serve in her role while she undergoes treatment.

"I am grateful to have an outstanding team of doctors who detected the cancer early and are guiding my care, and I am encouraged by a strong prognosis," Wiles said in a statement. "I am also deeply thankful for the support and encouragement of President Trump as I undergo treatment and continue serving in my role as White House Chief of Staff."
