  Fibrocystic breast disease is the most common benign type of breast disease, diagnosed in millions of women worldwide. Certain hormonal factors underpin the function, evaluation, and treatment of this disease. […] The main components of the breast are prone to fibrocystic changes during hormonal fluctuations. These components include the stroma, ducts, and lobules of the breast. During the reproductive age, glandular breast tissue has a direct relation to cyclical surges of plasma levels of estradiol and progesterone. […] The etiology of benign breast disease has demonstrated a strong clinical association with women receiving estrogen and anti-estrogen treatment. The prevalence of benign breast lesions in postmenopausal women receiving estrogens and progestins for over eight years is increased by 1.7 fold.

  Fibrocystic breast changes lead to the development of fluid-filled round or oval sacs, called cysts. The exact cause of fibrocystic breast changes isn’t known, but experts suspect that reproductive hormones especially estrogen play a role. […] Fluctuating hormone levels during the menstrual cycle can cause breast discomfort and areas of lumpy breast tissue that feel tender, sore and swollen. Fibrocystic breast changes tend to be more bothersome before your menstrual period and ease up after your period begins. […] When examined under a microscope, fibrocystic breast tissue includes distinct components such as: fluid-filled round or oval sacs (cysts), a prominence of scar-like fibrous tissue (fibrosis), overgrowth of cells (hyperplasia) lining the milk ducts or milk-producing tissues (lobules) of the breast, enlarged breast lobules (adenosis).

  Fibrocystic breast changes are a common noncancerous condition that can cause painful, lumpy breast tissue. […] The hormonal changes that occur just before your period can make you develop fibrocystic breasts, which can cause breast pain and tenderness. […] While experts aren’t entirely sure what causes fibrocystic breasts, they believe it relates to fluctuating levels of hormones especially estrogen during your menstrual cycle. Flare-ups of fibrocystic breasts tend to be most common just before your period when estrogen levels are lower. […] There aren’t any studies that show fibrocystic breast changes increase your risk for cancer or contribute to breast cancer. The only correlation is that it might be harder to spot precancerous or worrisome breast tissue in fibrocystic breasts. […] Your risk for breast cancer isn’t any higher if you have fibrocystic breasts. But changes in your breast tissue from fibrocystic breasts could make it slightly harder to detect tissue that may be cancerous.

• #4 Fibrocystic breast disease: pathophysiology, pathomorphology, clinical picture, and management – PubMed

  https://pubmed.ncbi.nlm.nih.gov/3511705/

  The pathophysiology of fibrocystic breast disease is determined by estrogen predominance and progesterone deficiency that result in hyperproliferation of connective tissue (fibrosis), which is followed by facultative epithelial proliferation; the risk of breast cancer is increased twofold to fourfold in these patients. […] Fibrocystic breast disease is not a „harmless nondisease” but a distinct clinical entity that requires treatment to bring about relief to the patient, to reduce the incidence of breast surgical procedures, and to diminish the risk of breast cancer.

  Fibrocystic change of the breast is a non-specific term referring to several types of benign Benign Fibroadenoma breast conditions. These are non-proliferative lesions, which include cystic and fibrous tissue formation. […] The pathogenesis is incompletely understood, but appears to be associated with hormone levels. […] Estrogen stimulates ductal elements (including adenosis). […] Progesterone stimulates stromal elements. […] Classic fibrocystic changes include cystic lesions derived from the terminal duct lobular unit, which form by dilation and obstruction of the efferent duct. […] Fibrosis results from ruptured cysts and chronic stromal inflammation, leading to palpable firmness on exam.

  Fibrocystic breast changes occur when thickening of breast tissue (fibrosis) and fluid-filled cysts develop in one or both breasts. It is thought that hormones made in the ovaries during menstruation can trigger these breast changes. This may make your breasts feel swollen, lumpy, or painful before or during your period each month. […] More than half of women have this condition at some time during their life. It is most common between the ages of 30 and 50. It is rare in women after menopause unless they are taking estrogen. Fibrocystic breast changes do not change your risk for breast cancer. […] If your breast exams and mammograms are normal, you do not need to worry about your symptoms. Fibrocystic breast changes do not generally increase your risk for breast cancer. However, if you have a family history of breast cancer and fibrocystic changes, there is a small increase in the risk. Symptoms usually improve after menopause.

  Fibrocystic change of the breast (also known as diffuse cystic mastopathy) is a benign alteration in the terminal ductal lobular unit of the breast with or without associated fibrosis. It is seen as a wide spectrum of altered morphology in the female breast from innocuous to those associated with an increased risk of developing carcinoma. […] Hormonal alterations with estrogen dominance over progesterone are considered to be an important factor. The alterations seen are subdivided into: […] Aberrations in Normal Development and Involution (ANDI) of the breast encompass all changes associated with normal variations in breast parenchyma due to hormonal fluctuations and aging. Therefore, fibrocystic changes are more appropriately classified under ANDI rather than being regarded as a pathological condition.

• #36 Fibrocystic breast changes – Wikipedia

  https://en.wikipedia.org/wiki/Fibrocystic_breast_changes

  Fibrocystic breast changes is a condition of the breasts where there may be pain, breast cysts, and breast masses. The exact mechanism of the condition is not fully understood, though it is known to be tied to hormone level fluctuation; the condition usually subsides after menopause and is closely related to the menstrual cycle. This condition is an accumulative process, partly caused by the normal hormonal variation during a woman’s monthly cycle. The most important of these hormones include estrogen, progesterone and prolactin. These hormones directly affect the breast tissue by causing cells to grow and multiply. Chronic hormonal fluctuations eventually produce small cysts and/or areas of dense or fibrotic tissue over the years. By the age of 30, multiple small cysts and breast pain may arise. Larger cysts usually do not occur until after the age of 35. Over time, presumably driven by aberrant growth signals, such lesions may accumulate epigenetic, genetic and karyotypic changes such as modified expression of hormone receptors and loss of heterozygosity. There is evidence that iodine deficiency contributes to fibrocystic breast changes by enhancing breast tissue sensitivity to estrogen.

  Experts believe there is a link between hormones and breast changes. Breast tissue responds to fluctuating levels of hormones, especially estrogen, leading to an overgrowth of epithelial cells and a buildup of breast tissue. […] People who develop fibrocystic changes may be more sensitive to hormonal fluctuations during the menstrual cycle. It is common for symptoms to become more bothersome right before or during a menstrual period. Taking hormone replacement therapy after menopause may also increase the risk. […] More recently, the results of a small 2023 study with 96 participants suggested that vitamin D deficiency is more common in women with fibrocystic breast disease and may play a role in the development of the disease. Therefore, it’s possible that vitamin D supplementation may be a future treatment option. However, more studies on this topic are necessary.

  Mastopathy (also called mammary dysplasia) is a benign breast disorder with changes in the glandular breast tissue. It occurs mostly in women between the age of 30 and 50. […] Hormonal imbalance is considered to be a the cause of mastopathy. […] The main cause of mastopathy is hormonal disorder, i.e., an imbalance between the hormones estrogen and progesterone responsible for regulating the menstrual cycle. Often estrogen levels are too high because of its excessive production in the body, or because of insufficient progesterone secretion. Excess estrogen can lead to the development of benign changes in the glandular tissue of the breast. […] Increased production of the hormone prolactin or androgens (male sex hormones) can also cause estrogen levels to rise. […] Estrogen overproduction may equally cause thyroid dysfunction with a decrease in blood levels of its hormones.

• #43 Fibrocystic breast changes – Wikipedia

  https://en.wikipedia.org/wiki/Fibrocystic_breast_changes

  Fibrocystic breast changes is a condition of the breasts where there may be pain, breast cysts, and breast masses. The exact mechanism of the condition is not fully understood, though it is known to be tied to hormone level fluctuation; the condition usually subsides after menopause and is closely related to the menstrual cycle. This condition is an accumulative process, partly caused by the normal hormonal variation during a woman’s monthly cycle. The most important of these hormones include estrogen, progesterone and prolactin. These hormones directly affect the breast tissue by causing cells to grow and multiply. Chronic hormonal fluctuations eventually produce small cysts and/or areas of dense or fibrotic tissue over the years. By the age of 30, multiple small cysts and breast pain may arise. Larger cysts usually do not occur until after the age of 35. Over time, presumably driven by aberrant growth signals, such lesions may accumulate epigenetic, genetic and karyotypic changes such as modified expression of hormone receptors and loss of heterozygosity. There is evidence that iodine deficiency contributes to fibrocystic breast changes by enhancing breast tissue sensitivity to estrogen.

  Fibrocystic breast condition involves the glandular breast tissue. The sole known biologic function of these glands is the production, or secretion, of milk. Occupying a major portion of the breast, the glandular tissue is surrounded by fatty tissue and support elements. The glandular tissue is composed of different types of cells: […] The most significant contributing factor to fibrocystic breast condition is a woman’s normal hormonal fluctuations during her monthly cycle. Many hormonal changes occur as a woman’s body prepares each month for a possible pregnancy. The most important of these hormones are estrogen and progesterone. They directly affect the breast tissues by causing cells to grow and multiply. […] Many hormones aside from estrogen and progesterone also play an important role in causing fibrocystic breasts. Prolactin, growth factor, insulin, and thyroid hormone are some of the other major hormones that are produced outside of the breast tissue, yet act in important ways on the breast.
