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: -For instance, cancer cells: grow in the absence of signals telling them to grow. Normal cells only grow when they receive such signals. ignore signals that normally tell cells to stop dividing or to die (a process known as programmed cell death, or apoptosis).

Detailed explanation-4: -Cancer cells, unlike the normal cells in our bodies, can grow forever. Cancer cell immortality leads to massive tumors, metastatic spread, and potentially re-emergence.
