Detailed explanation-1: -In cancer, the cells often reproduce very quickly and don’t have a chance to mature. Because the cells aren’t mature, they don’t work properly. And because they divide quicker than usual, there’s a higher chance that they will pick up more mistakes in their genes.

Detailed explanation-2: -Normal cells follow a typical cycle: They grow, divide and die. Cancer cells, on the other hand, don’t follow this cycle. Instead of dying, they multiply and continue to reproduce other abnormal cells.

Detailed explanation-3: -2) Please notice that cancer cells do not grow or divide faster than normal cells, although many people believe that, and most forms of chemotherapy were designed on the assumption that they grow faster.

Detailed explanation-4: -Cancers, however, occur due to an alteration of a normal biological process-cell division. Cells that progress through the cell cycle unchecked may eventually form malignant tumors, where masses of cells grow and divide uncontrollably, then develop the ability to spread and migrate throughout the body.
