Breast Cell Response

Meaning

Breast cell response denotes the specific molecular and physiological changes that mammary epithelial and stromal cells undergo in reaction to circulating hormones, local growth factors, and paracrine signals. This encompasses the full spectrum of cellular activity, including proliferation, differentiation, programmed cell death, and the modulation of specific gene expression patterns. Understanding this cellular sensitivity is central to assessing breast health across the lifespan and predicting the impact of both endogenous and exogenous hormonal exposures. The response profile dictates the long-term health and risk status of the breast tissue.
