DNAm age and DNAm age acceleration in tumor and adjacent normal breast tissue. A Correlation of DNAm age with chronological for each tissue type (blue = normal, red = tumor); B Distribution of DNAm age acceleration by tissue type. Pearson correlation coefficient (R) and P values were computed for each tissue type. Kruskal–Wallis test was used to formally assess median differences in DNAm age acceleration across tissue samples
