Outcomes in differentiated thyroid cancer, or DTC, do not significantly differ between patients with a history of radiation exposure and those without, but a history of radiation exposure may improve overall survival, according to study findings.
“Over the past 20 years, the incidence of DTC has skyrocketed,” the researchers wrote. “Paralleling this rise has been an enormous increase in the use of medical radiation. As radiation is a major risk factor for DTC, these observations have led some investigators to suggest that increased use of medical radiation has contributed significantly to the burgeoning incidence of DTC. Little is known, however, about the effect of medical radiation on outcomes for DTC.”
