Estrogen is scientifically validated as a key hormone in supporting the breast body system. Estrogen is a primary female sex hormone produced mainly in the ovaries, and its effects on breast tissue are well documented in the medical literature. During puberty, rising estrogen levels stimulate the growth and development of breast tissue, primarily through the proliferation of the ductal system and deposition of fat, leading to the development of mature female breasts. This process is critical for normal female sexual development.

Throughout reproductive life, estrogen continues to influence breast physiology, regulating the menstrual cycle by promoting ductal growth and preparing the breasts for potential lactation. Multiple studies have shown that withdrawal of estrogen, such as during menopause, leads to involution (shrinkage) of breast tissue, while supplementation with estrogen (as in hormone replacement therapy) can maintain or increase breast tissue volume in postmenopausal women.

However, long-term or excessive exposure to estrogen is also linked to an increased risk of breast cancer, as it stimulates the proliferation of breast cells, potentially increasing the risk of mutations. This dual role is well supported by both experimental and epidemiological studies.

In summary, the use of estrogen to support the breast body system is thoroughly supported by scientific research, with a deep understanding of its physiological role in breast development and maintenance.
