cancer cure

The esophagus, like all body tissues, is made up of individual cells. Normally, cells within the forming esophagus divide and grow very rapidly in the womb, in early childhood, and through puberty. In adulthood, new cells are only formed to replace those which have died from injury, old age or disease. The division of cells to produce new ones is under tight control by the "genes" within each cell. These genes are made up of DNA, and if it becomes damaged, the cell may start dividing out of control.Esophagus cancer starts in a single cell which has become abnormal. This cells produces millions, and eventually billions, of copies of itself. The copies are called"clones". These clones fail to function as normal esophagus tissue, but instead divert resources from healthy cells to fuel their own growth. When there are about 1 billion cells, they form a clump, or "tumor" 1/2 inch across. A "tumor" merely means a swelling, it can be caused by infection, inflammation, cancer or whatever. If a tumor only grows in it's local area (even very large) but does not have the capacity to spread to distant body areas, it is called"benign" and isnot cancer. If, however, the tumor has the ability to spread to distant body areas, it is called "malignant" andthis is cancer. The actual process of spread is called"metastasis", and can occur to any area of the body.



The most common type of benign esophageal tumor arises from the muscular layer, and is called a "leiomyoma". Unfortunately, a quickly growing tumor within the esophagus is most likely to be cancerous.
