Susie Wiles reveals the brutal reality of fighting breast cancer while running Trump's White House — saying some days, just getting out of bed, getting dressed and going to work was its own test. In a rare personal op-ed, the chief of staff described carrying the full weight of chemotherapy and one of Washington's most demanding jobs at the same time. The disease occupied her thoughts from the moment she woke up and sometimes even while she slept. Treatment took a toll on her stamina, mobility and focus, but she said work gave her a purpose beyond the scans and side effects. After successful surgery, pathology showed no residual cancer. Wiles now faces the work of rebuilding what treatment took from her.
