We observed strong associations between BMI change over the life course and mammographic breast density. The inverse associations between early life adiposity change and volumetric percent density suggest that childhood adiposity may confer long-term protection against postmenopausal breast cancer via its effect of mammographic breast density.

We conducted a nested case-control study in the Prostate Cancer Prevention Trial (PCPT). Cases (n=1,128) and controls (n=1,205) were frequency matched on age, first-degree relative with prostate cancer and PCPT treatment arm (finasteride/placebo); African-Americans were oversampled and case/control status was biopsy-confirmed. We selected 21 SNPs in vitamin D-related genes (VDR, GC, C10orf88, CYP2R1, CYP24A1, CYP27B1, DHCR7, NADSYN1) to test genotype and genotype-treatment interactions in relation to prostate cancer. We also tested mean serum 25(OH)D differences by minor allele distributions and tested for serum 25(OH)D-genotype interactions in relation to prostate cancer risk. Log-additive genetic models (Bonferroni-corrected within genes) adjusted for age, BMI, PSA, and family history of prostate cancer revealed a significant interaction between treatment arm and GC/rs222016 (finasteride OR=1.37, placebo OR=0.85, p-interaction less inimal associations of vitamin D with total or high-grade prostate cancer.

This phenomenon, which can be primed by R-loops, is called constitutive stable DNA replication (cSDR)
