Barbara Hilija Spiessl, a fifth-degree black belt in Taekwon-Do, was diagnosed with subcutaneous panniculitislike T-cell lymphoma, a rare subtype that accounts for less than 1 percent of all non-Hodgkin lymphomas. During her treatment and recovery, Spiessl called upon her Taekwon-Do training to find the strength and resilience to manage the long-term side effects from treatment.
