Nipples also have sebaceous glands , which secrete small amounts of lubricating material. As previously mentioned, breasts change in the same way as the rest of our bodies do through life. Young women's breasts are dense, glandular structures needed for producing milk, but as you age, your breasts become fattier and less glandular. Post menopausal women have nearly no milk glands as they are slowly replaced with fatty tissue as you age. As a result, breasts become softer and less lumpy.
Many women also notice changes in their breasts during their menstrual cycle.
Fluid retention in breast tissue can cause your breasts to enlarge about two weeks before your period, but this usually subsides once your period begins. Breasts, like other parts of your body can suffer infections, swelling, have localised pain or discharge. Cysts Cysts are very common, particularly in women in their 30's, 40's and 50's and are most common in menopausal women. Some health professionals have a tendency to call all non-malignant lumps cysts, but cysts are a particular type of lump. A cyst is caused by fluid trapped in breast tissue forming a sac like a large blister.
