Diagnosed at 8 with non Hodgkin lymphoma, Florence is thriving at 17.

February 4, 2014, is a date seared in the mind of Ian Kirouac. That’s the day his daughter, Florence, was diagnosed with non-Hodgkin lymphoma (NHL).

A few months earlier, the then-eight-year-old had developed a strange red patch on her chest that would not go away. She otherwise felt healthy, except for occasional night sweats. The family doctor prescribed a medicated cream that had no effect, then suggested Florence see a dermatologist, who took a biopsy.
