From: Established breast cancer risk factors by clinically important tumour characteristics

Predictors of invasive breast cancer risk in the Polish Breast Cancer Study by histological subtypes. Odds ratios (95% CI) for ductal carcinomas, NOS (N=1,251) are shown in black, for lobular carcinomas (N=342) in blue, for tubular carcinomas (N=119) in red, and for mixed carcinoma (N=252) in green. Numbers in brackets denote statistically significant heterogeneity of ORs for lobular, tubular, and mixed compared to ductal carcinomas, NOS, respectively, based on standard polytomous logistic regression among cases: (1) 0.13, 0.002, and 0.98. Analyses are adjusted for age, study site, menopausal status, education level, family history, prior benign breast biopsy, screening mammogram, and all other factors shown in the figure. Comparison groups are 5-year increases for ages at menarche, first full-term birth, and menopause; each additional birth for number of full-term births; never HRT users for current or recent use of combined HRT; 5 unit increases for BMI.
