 When Wiley was 10-years-old, doctors discovered an extremely rare tumor known as an inflammatory myofibroblastic tumor between her right lung and her diaphragm.  An IMT occurs in less than one in one million people and roughly 150–200 cases occur in the United States each year. The tennis ball sized tumor was pressing on her lung and causing high fevers, extreme fatigue and headaches.  IMT's are usually benign but Wiley's was not.  Doctors were able to completely remove the tumor surgically and no further treatments were necessary other than routine checkups.  During the surgery, parts of her lung and diaphragm were removed and are held together today by two titanium staples.
 In September 2023, in conjunction with her first track meets on the European circuit and Childhood Cancer Awareness Month, Wiley announced a fundraiser for patients at Riley Hospital for Children in Indianapolis, the hospital where she received her life saving cancer treatments ten years earlier.  She promised to match donations up to $5,000.  She has previously stated in an interview, "As a cancer survivor, I also like advocating for other children battling cancer, as a professional runner someday I plan to donate a large portion of my prize money to support children experiencing cancer."
