Fibrocystic changes refer to non-cancerous alterations in the breast tissue, which are common in women. These changes often involve the development of lumps, cysts, and areas of dense or fibrous tissue. Fibrocystic changes are part of a benign condition known as fibrocystic breast disease, which can cause discomfort or pain, especially before menstruation.
The exact cause of fibrocystic changes is not well understood, but hormonal fluctuations, particularly those involving estrogen and progesterone, are believed to play a significant role. These hormones stimulate the breast tissue, leading to the formation of lumps and cysts. The condition is most common in women of reproductive age, typically between 20 and 50 years old.
