Understanding Breast Cancer Risk

Breast cancer risk is influenced by both natural and external hormone factors. Natural factors include early menstruation, having no children, or having a first child at an older age. External factors can be hormone therapies used during menopause. These elements affect the breast's development and hormone exposure, which can increase cancer risk.

Breast Anatomy and Cancer Development

The breast comprises skin, tissue, and ducts that connect to the nipple. Cancer often originates in the terminal ductal lobular unit (TDLU), which is the functional unit of the breast. Differences in these structures can influence the likelihood of developing cancer.
Breast cancer is a malignant tumor that originates in the cells of the breast, most commonly in the terminal ductal lobular unit. It is influenced by hormonal, reproductive, and anatomical factors.

Hormones and Breast Cancer

Both estrogen and progesterone play significant roles in breast tissue development and cancer risk. Estrogen promotes cell growth, and when combined with progesterone, it influences breast development. Hormone receptors in the breast can make it more susceptible to cancer when exposed to these hormones.
