Influence of financial burden on withdrawal or change of cancer treatment in Japan: results of a bereavement survey.

Fewer participants reported withdrawal or change of cancer treatment than in previous studies, which might reflect the characteristics of the Japanese healthcare system.

Medical staff should consider financial toxicity as a serious side effect and assist patients in their decision-making regarding treatment while taking into account their socioeconomic backgrounds.
