Oestrogen receptor (ER), progesterone receptor (PR) and Ki-67 staining of high mammographic density (HMD) and low mammographic density (LMD) tissue samples. Representative photomicrographs show ER, PR and Ki-67 brown nuclear staining in selected HMD and LMD regions of the 15 women. The percentages of positive nuclear staining in glandular areas per whole tissue section were point-counted using JMicroVision, and the results were analysed using paired t tests
