The Nipple
Nipple protruding from the center of the breast and gives milk, made in the mammary gland, for the baby. It is also an erogenous zone. In women, the nipple contains outlets from 15 to 20 lactiferous ducts, arranged cylindrically around the tip. Pigmented circle of skin surrounding the nipple known as the areola, and a small lump which decorate the Montgomery tubercles.
During fetal development, some nipples grow with what is known as the "milk lines" which runs on each side, from chest to groin. If more than two of these survive, the extra-called supernumerary nipples. In other mammals, the number of women are born with nipples tend to determine the maximum size of each litter he could produce.
Putting can behave abnormally in a variety of ways. Some do not stick properly, which is known as inversion. Non-lactation-related discharge can indicate a number of diseases, including pituitary gland tumor called a prolactinoma. Babies may even produce milk for a short time after birth ("fake milk ‘) because of the effects of estrogen in their bodies the mother.
But the most serious conditions to affect parts of the body is Paget’s disease of the nipple. Most common in postmenopausal patients (although it can also affect men and young women), it announces itself with itchy, sore nipples or cracked, often accompanied by bloody discharge. That Paget was malignant and, although sometimes limited to the nipple area, it usually signals the presence of an underlying breast cancer. It is easy to diagnose with a tissue biopsy, although the problem is that people tend to seek help late Paget’s because they think they only have eczema. Treatment is by surgery.
