Suffering on Cancer

The Crab or cancer (medical name: malignant tumors) is a group of diseases in which a group of cells show characteristics of uncontrolled growth (growth and the division beyond the normal limits), Invasion (infiltration and destruction of adjacent tissue) and sometimes Metastases (also in other places in the body through the blood or the lymph). These three characteristics of malignant tumors to distinguish tumors, which itself is limited, not invade or metastases. Most cancers form of a tumor, but some, such as leukemia, do not.

Cancer May impact on the people of all age groups, and including fetus, but the risk for the common catalogue of varieties tend to continue with age. The cancer is responsible for about 13% of all deaths. According to the American Cancer Society, 7.6 million people died from cancer in the world in 2007. The crabs can spread to other animals and also the people who plant.

Almost all types of cancer are covered by the anomalies in the genetic material of the cells are processed. These anomalies May-be because of the effects of carcinogens, such as smoking, radiation, chemicals or infections. Other promotion of cancer genetic abnormalities May be purchased at random errors in the replication of DNA, or inherited, and thus in all cells of the birth. A complex interaction between carcinogens and the host genome May explain why only some develop cancer after exposure to a carcinogen. New aspects of genetics of cancer in the pathogenesis, such as DNA methylation, microRNAs and are increasingly recognized as important.
