Cancer is a group of diseases in which cells grow and divide aggressively without beyond to normal limits, invade and destroy adjacent tissues and spread to other locations in the body. Cancer is usually classified according to the tissue from which the cancerous cells originate. Cancer cells continue to grow and divide so they are different from normal cells. Cancer may affect people at all ages, even fetuses, but risk for the more common varieties tends to increase with age. Cancer causes about 13% of all deaths. A definitive diagnosis usually requires the histological examination of a tissue biopsy specimen by a pathologist. A tumor marker is a substance found in the blood, urine, or body tissues that can be elevated in cancer, among other tissue types. The objectives of this research project are to preliminary screening of population in order to determine prevalence of cancer by using tumor markers and to diagnose cancer at early stage, when it is most curable.
