Although there are also diseases in the skin covering the breast; It is not much different from the skin on other parts of the body. An important detail is the nipple. The special formation that is raised on the surface to make it easier for the baby to suckle is the end point of the milk ducts. There are some diseases specific to the nipple. However, in this section, the tissues inside the breast are examined.
There are basically 3 types of tissues in the breast; a) milk-producing tissue (glands and ducts), b) supporting connective tissue and c) fatty tissue.
a) Milk-producing tissue, round glands (lobules) that produce this special liquid and the duct (duct) that carries milk to the nipple. It consists of the ductus system. Small ducts merge and eventually form large ducts, the number of which opens per nipple varies between 12-20. Although these channels are knotted within themselves, they generally follow a straight line of radial type towards the nipple. Milk-producing tissue is more abundant in the upper outer part of the breast.
Cancer of this tissue type is most common. In the type of cancer called ductal carcinoma in situ, which grows in the duct and does not pass into the breast tissue, cancer cells can progress along these ducts and move to other foci.
b) The supporting connective tissue starts from the chest wall and extends to the skin in strips. It compartmentalizes and transports milk-producing tissue. It is responsible for the shape of the breast. Since it is carrier and shaper, it is harder than other tissues in the breast.
Malignant disease of this tissue is rare.
c) Fat tissue fills the gaps in between and replaces other tissues, which decrease in volume with age.
Almost no malignant diseases are observed in this tissue. However, fat glands seen in the fat tissue on other parts of the body can also be detected in the breast.
There are some definitions to determine the location of the masses detected in the breast and to ensure unity in communication. Considering the nipple as the center, the breast is divided into 4 quadrants (upper inner, upper outer, lower inner and lower outer). Another frequently used definition is clock modelling. The direction of mass or change is made according to the hour positions on the hour and minute hands. For example, when a mass is mentioned in st 2 of the left breast, this corresponds to the upper outer part of the left breast. But be careful!!!. In the right breast, st 2 definition corresponds to the upper and inner.
