Document Summary
However, the mechanism can go wrong leading to disruption of the body"s structure. Cancer is now the major cause of death in na. Causes and mechanism of cancer: cancer cell proliferate, invade & metastasize. Individual cell adjust its needs according to the need of the whole organism. Divide or not, live or kill itself, maintain appropriate specialized character, occupy its proper place. If 1 cell misbehaves no harm, but if the cell has genetic alteration that allows it to survive and divide when it should not, producing many more cell of its kind. Types of cell misbehaviour that contribute to cancer progress. Cancer cells are defined by 2 heritable properties: 1- proliferate with less regard to the normal constraints, 2- invade and colonize areas reserved for other cells. Cells with property (1) only are benign (remain clustered in a single mass), it can be removed surgically.
