Breast development, also known as mammogenesis, is a complex biological process in primates that takes place throughout a female's life. It occurs across several phases, including prenatal development, puberty, and pregnancy. At menopause, breast development ceases and the breasts atrophy.
A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring.Mammals get their name from the Latin word mamma, "breast".The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs ...
Breast development throughout pregnancy may result in significant Areola and Areolar gland enlargement, erectile nipples, and/or nipple sensitivity. [8] [9] A woman's breasts grow during pregnancy, typically 1 to 2 cup sizes. [10] A woman who wore a C cup bra prior to her pregnancy may need to buy an F cup or larger bra while nursing. [11]
Newborn infants often produce some milk from their own breast tissue, known colloquially as witch's milk. In most species, lactation is a sign that the female has been pregnant at some point in her life, although in humans and goats, it can happen without pregnancy.
The majority of breast diseases either originate from lactiferous ducts or are closely related. The high susceptibility to benign and malignant diseases is in part a consequence of the cycling hormonal growth stimulation resulting in a high cell turnover and accumulation of defects and complicated hormonal equilibrium which is highly sensitive ...
The number for prolactin cells in a pregnant female will increase to allow for breast tissue development. Prolactin is involved in the maturation of mammary glands and their secretion of milk in association with oxytocin, estrogen, progesterone, glucocorticoids, and others. Prolactin has numerous other effects in both sexes. [citation needed]
The study suggests that around 8 mg of zinc daily from food could be a suitable target for most non-pregnant women, potentially lowering the risk of endometriosis compared to higher intakes.
