Introduction

The diagnosis of cancer is now no longer a death sentence. If the disease is discovered in time, it is curable in many cases. The earlier cancer is treated, the greater are the chances to be completely healthy again. It is therefore particularly important to pay attention to changes in body and in doubt, ask the doctor. Despite the medical advances in cancer treatment, cancer continues to account for many people fear.

Despite the continuing advances made both in terms of treatment of detection and prevention, cancer remains one of the most frightening diseases for most of us.

When cancer is malignant cells, in which the control mechanism of growth, maturation, division and death is disturbed by cells. Cancer cells divide due to this disorder more often than healthy cells, so it is an uncontrolled proliferation and a tumor or a tumor forms. These malignant (malignant) cancer cells can invade adjacent tissues, multiply, and destroy there by and by the healthy tissue (Buxton, et al, 2003).

Cancer

Cancer is an abnormality, a disorder that affects the cells of our body. Our body is composed of a multitude of cells, each specialized in a specific function, such as filter impurities from the blood (renal cell) or transport oxygen throughout the body (blood cells). These cells have their life cycle: Every day, thousands of them die (known as apoptosis, ie programmed cell death) and are replaced by new cells. The cells renew themselves by dividing. When we talk about a type of cancer cell multiplies an abnormal and uncontrolled. There are over one hundred forms of cancer, the severity varies. All parts of the body can be affected.

Instead of the term "cancer" is often used the word "tumor" which translates something like "swelling" or "hardening" means. Doctors use the term for any tumor swelling - even those who have nothing to do with cancer. Thus, known as hardening, caused by inflammation of the will, an effusion or the like, as well as a tumor. If we are talking about a tumor, this must have done so far to do with cancer. Rather, the tumor can be benign (benign).

Understanding What is Cancer

This is the genome of each cell that control its operation.

The genome is the genetic heritage of the cell, carried in its core: it contains about 100,000 genes, which "give orders" to the cell (dividing, to specialize or die ...). It allows the cell to live harmoniously with its environment (trade with neighboring cells) and its role in the body.

The genome of the cancer cell is damaged: the orders he gives are incorrect and the cell can no longer function normally. Cancer cells compared to normal cells, are characterized by:

Immortality: Unlike normal cells, the number of divisions is limited, cancer cells reproduce indefinitely (Evans, 2005).

Independence: they do not respect the "laws" of the organization and no longer obey the messages of their neighbors.

Inability to produce specialized cells.

Infiltration capacity and migration: whereas normal cells are linked together ...
