What prison cadre function appears to go awry in the national of crabmeat booths ? How can this damage an individualIn crabby person cell the nearly important function bear upon is the cell division or multiplication of cells . When a single cell starts to divide uncontrollably it becomes malignant neoplastic diseaseous . In normal conditions , when a cell starts to stick surface in a different way as that of surround cells , the body has its own mechanism to destroy the cell : all by phagocytosis (by specialized cells of the immune system ) of the affected cell or lysis of the cell by different lytic enzymes with in the cell . Similarly when a cell becomes senile it will be killed by a programmed way called apoptosis . But in cancer cells , they fail to execute apoptosis of the cells as hearty as to check the uncontrolled division . So in cancerous cells , former(a) than cell division , cells fail in apoptosis , fail to establish contact inhibition (as expiry cell grow one over anther leading to liberal masses of cancerous harvesting .More over cancer cell do not differentiated or mature to a specific lineage , they remain in a uniform stage and immortal . With uncontrollable division , the genetic culture with in the cell would be completely lost or mutated and the cells override the normal cell signaling functions .

There be proteins which will be coded from the mutated genes or chemical agents can set forth certain genes `oncogenes to become functional leading to onset of cancer There are three genes which becomes abnormal in cancer oncogenes , tumor suppressor genes , and genes that repair DNA damagesWhen the cells grow with out any control , grow into `tumors or cancerous growth . Tumors can be divided into two : benign and malignant . Benign tumors are confined to a particular region of the body where they develop they do not rotate to other parts of the body . But the malignant tumors develop metastasis and spread to different parts of the body through blood or lymphatic system . Till date there no effective treatment has been found out to combat cancer . People affected with malignat type of cancers are terminally affected and they finally succumbed to death irrespective of the age or sexReference : genus Cancer Medicine , Kufe , Donald W Pollock , Raphael E Weichselbaum , Ralph R bast fiber , Robert C , Jr Gansler , Ted S Holland James F Frei III , Emil , editors .Hamilton (Canada : BC Decker Inc c2003PAGEPAGE 1...If you want to get a full essay, order it on our website: Orderessay
