Brystkjertelvevet

Brystkjertelvevet, also known as mammary gland tissue, is a specialized glandular tissue found in mammals, including humans. Its primary function is the production of milk to nourish offspring. In females, this tissue develops significantly during puberty under the influence of hormones like estrogen and progesterone, becoming more prominent during pregnancy and lactation.

The structure of brystkjertelvevet consists of lobes, which are clusters of smaller lobules containing milk-producing alveoli. These lobules are connected by a network of ducts that eventually merge to form larger ducts leading to the nipple. The tissue also contains connective tissue and fat, which provide support and contribute to the overall size and shape of the breast.

In males, brystkjertelvevet is present but typically remains underdeveloped and non-functional. Hormonal imbalances can sometimes lead to the development of breast tissue in males, a condition known as gynecomastia.

Changes in brystkjertelvevet can occur throughout a woman's life, influenced by the menstrual cycle, pregnancy, breastfeeding, and menopause. It is also an area where various conditions can arise, including benign growths like fibroadenomas and cysts, as well as malignant conditions such as breast cancer. Regular self-examination and medical screenings are important for monitoring the health of brystkjertelvevet.
