VALIDATION OF SCREENING MODEL OF CANCER: A REVIEW

Abstract

Cancers are characterized by uncontrolled cell division and the development of metastatic qualities. The reason for the cause of cancer can be intrinsic 
factors like oncogenes, external factors like radiation, certain chemical exposure, etc., or biological like infection from certain viruses, bacteria. Hence, 
because of these factors, 200 different forms of cancer exist making cancer a leading of death and major health problem even in the present world. 
However, the lack of a comprehensive understanding of cancer biology in the modern period is a significant impediment to studying cancer tumour 
formation, invasion, and metastasis. Hence, cancer models can be crucial in removing that impediment and can give us a better understanding of the 
cancers because even in the 21st-century cancer is still an unsolved puzzle and with cancer models like in vivo models, In-vitro models and computerized 
models a better understanding can be achieved.
