Individuals with breast cancer are especially prone to high out-of-pocket costs (OOPCs). We aimed to evaluate the FT rate of individuals with breast cancer and determine particularly vulnerable patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A comprehensive search of PubMed\/Medline, Embase, Global Index Medicus, Web of Science (WOS), and EBSCO was performed from inception to July 28, 2025. Studies on FT in participants with breast cancer were included. Pooled estimates of FT rates with 95% confidence intervals (CIs) were calculated using the random-effects model. The primary outcome was FT. The secondary outcomes included the rates of participants in high-income countries (HICs), middle-income, and low-income countries (LMICs) who incurred FT based on income, OOPCs, or patient-reported impact of expenditures during diagnosis and treatment of breast cancer.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Sixty-six studies involving 29\u2009426 participants with breast cancer were enrolled in our study. Most studies were from HICs (46 studies), and the others were from LMICs (20 studies). The definition of FT was significant difference among these studies. The pooled FT rate was 39.3% (95% CI, 32.4%-46.6%) in HICs and 72.3% (95% CI, 56.8%-83.8%) in LMICs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>FT is a substantial burden among patients with breast cancer worldwide.
