What Are the Causes of Thickness in Breast Tissue?
The breasts contain large amounts of glandular tissue, organized into milk-producing lobules and milk-transporting ducts. The lobules and ducts form a complex tree-like structure that connects to the nipple. Normal fluctuations in breast growth can change the palpable consistency of the breasts during menstruation or pregnancy, but a sudden thickening of the breast tissue can indicate the presence of a severe underlying disorder.
