Résumé

Objective To estimate the associations between occupational exposure to textile fibers/dusts, and incidence of postmenopausal invasive breast cancer.

Methods

A population-based case-control study conducted in Montreal (2008 − 2011) identified hospital cases (N = 695) and population controls (N = 608) from the electoral list. Occupational hygienists examined participants’ occupations and tasks, and attributed exposures to several textile fibers. For all tumors and according to biomolecular subtypes, odds ratios (OR) and 95% confidence intervals (95%CI) were estimated using logistic regression models with different exposure indices, adjusting for potential confounders.

Results

Ever exposure to cotton dust was associated with an increased risk (OR = 1.42, 95%CI = 0.95-2.16) as was ever exposure to treated textile fibers before age 36 years and/or before first full-term pregnancy (OR = 1.39, 95%IC = 0.97-2.01).

Conclusions

These suggestive associations and the rapid evolution of textile fibers treatment warrant additional scrutiny, especially among younger women.
