Question

Answer 1

 Cancer is a collection of related diseases, the body cells begin to divide without stopping and spread into surrounding tissues. It is made up of trillion of cells and starts anywhere in the human body; when cells grow old or become damaged, they die, and the new cells take their place.

As they become more and more abnormal, old or damaged cells survive when they should die, and new cells form when they are not needed, these extra cells form growths called tumors. It grows and invades other tissues which makes it a cancer cell.
