Mammographic density is recognised as a useful phenotypic biomarker of breast cancer risk. Deeper understanding is needed of the cellular basis, but evidence is limited because of difficulty in designing studies to validate hypotheses. The ductal epithelial components do not adequately explain the physical and dynamic features observed. The stroma is thought to interact with ductal structures in cancer initiation. Stromal tissues might account for the mammographic features, and this interplay can be hypothesised to relate risk to density. In a paper in this issue of Breast Cancer Research, Alowami has shown a relationship between density and stromal proteins, which might provide useful insight into mammographic density.
乳腺密度被认为是乳腺癌风险的一种有用的表型生物标志物。需要对其细胞基础有更深入的了解,但由于难以设计研究来验证假设,相关证据有限。导管上皮成分无法充分解释所观察到的物理和动态特征。间质被认为在癌症发生过程中与导管结构相互作用。间质组织可能是乳腺钼靶特征的原因,并且可以假设这种相互作用将风险与密度联系起来。在本期《乳腺癌研究》的一篇论文中,阿洛瓦米展示了密度与间质蛋白之间的关系,这可能为乳腺钼靶密度提供有用的见解。
