President Donald Trump's White House chief of staff, Susie Wiles, shared that she has been diagnosed with breast cancer. "Nearly one in eight women in the United States will face this diagnosis," Wiles, 68, said in a statement to The New York Times on Monday, March 16. "Every day, these women continue to raise their families, go to work and serve their communities with strength and determination. I now join their ranks." Wiles shared that her cancer was caught in its early stages and will soon begin a course of treatment lasting several weeks in the Washington area.
