Association between primary language, a lack of mammographic screening, and later stage breast cancer presentation

Background

Health determinants are known to influence the stage of breast cancer presentation, but it is unclear to what extent language affects stage. This study investigates whether non–English‐speaking (NES) patients present at a later stage than their English‐speaking (ES) counterparts and whether language is associated with mammographic screening.

Methods

This study was a retrospective, single‐institution cohort analysis of women undergoing breast radiotherapy from 2012 to 2017 (n = 1057). Patients were categorized as ES (n = 904) or NES (n = 153). Ordinal logistic regression analysis identified variables associated with later stage presentation, including language, race/ethnicity, and age. A subcohort analysis investigated the influence of mammographic screening on stage for NES patients.

Results

NES patients had greater odds of later stage disease than ES patients (odds ratio, 1.47; 95% confidence, 1.001‐2.150). This association persisted across all races/ethnicities. An additional analysis examined age categories associated with mammographic screening. For women eligible for screening (ie, those 40‐50 years old or older than 50 years), there was a significant association between language and stage. NES patients older than 50 years were twice as likely to present at an advanced stage in comparison with ES patients (16.19% vs 8.11%; P = .0082). An additional subset analysis accounted for mammograms. NES patients who did not undergo screening had a higher probability of stage III disease (40.3% of NES patients vs 12.7% of ES patients). There was no difference in stage between NES and ES patients who did undergo screening.

Conclusions

Language is independently associated with later stage breast cancer for NES patients, regardless of race/ethnicity. NES patients may have difficulty in accessing the health care system. Future interventions should seek to reduce language barriers for mammographic screening and diagnosis.
