How does cancer happens?

Answer 1

Cells in our body grow, divide, and die in a certain way. Cancer happens when cells either grow, divide, or die wrong or in the wrong way. It ends up being an unpredictable manner that causes uncontrolled growth and division.

Answer 2

Cancer cells escape normal cell cycle timing and they replicate at their own rate. Cancer cells do not respond to normal control mechanisms. They divide excessively and start to invade other tissues in the body. Cancer cells do not follow density dependence, anchorage dependency, nutrient requirements, and growth factor requirement.
