E3N is a prospective cohort of French women aged 40-65 years at inclusion in 1990. Cancer data were collected at baseline and updated every 2-3 years. Hazard Ratios (HRs) and 95% confidence intervals (CIs) for associations between pigmentary traits and sun exposure, and risk of CLL/NHL were estimated using Cox models. With a median follow-up of 24 years, 622 incident cases of CLL/NHL were ascertained among the 92,097 included women. The presence of nevi was associated with CLL/NHL ri..
