Humans. As a woman ages, breast lobules involute and the number and size of acini per lobule in the breast decreases. The intralobular stroma is initially replaced by collagen followed by a gradual replacement of both glandular tissue and collagen by fatty tissue (Hutson et al., 1985 ).
What is breast cancer?
Breast cancer is an uncontrolled growth of epithelial cells originating in the ducts or breast lobules Carbone et al (1993). The disorder includes early, noninvasive breast cancer, such as ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS), breast cancer that has invaded the surrounding breast stroma (primary invasive breast cancer); and breast cancer that has spread to the draining lymph nodes or to distant organs (advanced or metastatic breast cancer). The disease is differentiated from benign breast pathologies, such as fibroadenoma, fibrocystic disease, or benign hyperplasia.
What is fibroadenomas in women?
Fibroadenomas arise from breast lobules and are the most common solid benign masses in women younger than age 30 years. Once diagnosed, fibroadenomas may remain stable in 80% of cases, regress in about 15%, and grow in 5% to 10%. Fibroadenomas are benign, although cancer can occur within a fibroadenoma. Women with a specific histologic diagnosis of complex fibroadenomas have cysts or histologic elements other than the fibroadenoma and have a small increased risk of future breast cancer, as described by DuPont and colleagues. Fibroadenomas may be single or multiple and are called giant fibroadenomas if larger than 8 cm.

fatty tissu e fills in the spaces between glandular and fibrous tissue and largely determines your breast size. Doctors refer to all non-fatty tissue as fibroglandular tissue. There are also bands of supportive, flexible connective tissue called ligaments, which stretch from the skin to the chest wall to hold the breast tissue in place.

A healthy female breast is made up of 12–20 sections called lobes. Each of these lobes is made up of many smaller lobules, the gland that produces milk in nursing women. Both the lobes and lobules are connected by milk ducts, which act as stems or tubes to carry the milk to the nipple.
What is the tissue in the breast called?
Adipose Tissue. The female breast is mostly made up of a collection of fat cells called adipose tissue.
