What is the breast epithel?
breast epithelium is a cell tissue lining milk produced by breast channels. These cells form the first line of defense against uncontrollable proliferation of breast cancer. Up to 80 percent of all breast tumors come from breast epithelial cells. Depending on the severity of the growth of malignant tissue, there are several ways that oncologists can sampling the epithelial breast tissue to avoid the extensive growth of damaged epithelial cells into healthy cells lining pipes.
The first character that the breast epithelium breaks when the genes of normal epithelial cells are damaged. Normally there is a gene that produces antibodies to cancer cells and another gene that maintains a balance between the number of birth and dying of cells. When these genes are destroyed through the environmental agent, the epithelial cells are no longer able to form a continuous defense boundary around the milk -producing pipes and cancerative cells are proliferated.
Several techniques are used to collect, bewareOutline and identifying precancerous cells from compromised breast epithelium, including ductal gaskets, aspiration of fine needles and biopsy. Aspiration of a fine needle is a safe procedure in which a hollow needle is inserted into the suspect area and the cell group is carefully removed. Biopsy is a more radical procedure in which a large amount of tissue is cut from the breast epithelium when the mass has already been discovered.
Ductal rinsing is a technique used to prevent cancer cells from traveling behind a single pipe into a new pipe tissue. It is only used in the breast that produces liquid when it is to apply the pipeline. A thin catheter injures a salt solution that releases some cells from the lining of the pipe before starting. After examination, the removed liquid may contain some precancerous cells.
As people get older, their tissue is reproducing more slowly and shrinking. The more pectoral tissue shows forImprients of slower growth and shrinkage with age, called involution, lower breast epithelium cancer. The larger the density of the breast tissue, which is the number of cells per cubic area of the breast, the better this chance that one cell will break and become cancerous. Although estrogen has been selected as a possible cause of breast cancer, it has been found that the action of estrogen itself in some cases promotes survival and promotes the proliferation of cancer cells in others.
