Cancer is ____
A
alcohol
B
Bad food molecules
C
Photosynthsis
D
out of control mitosis
Explanation: 

Detailed explanation-1: -Mitosis occurs infinitely. The cells never die in cancer, as cancer cells can utilize telomerase to add many telomeric sections to the ends of DNA during DNA replication, allowing the cells to live much longer than other somatic cells. [3] With this mechanism, cancer cells that usually die simply continue to divide.

Detailed explanation-2: -Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators.

Detailed explanation-3: -Answer and Explanation: When the cell division is not controlled, it is called uncontrolled cell growth. If the cell division is not controlled, there would be an unrestricted overgrowth of the cell mass. The uncontrolled cell growth is commonly known as tumour cell.

Detailed explanation-4: -A failure of the mitotic process generates cells that carry abnormal chromosome numbers. Such cells are predisposed to become tumorigenic upon continuous cell division and thus need to be removed from the population to avoid cancer formation.
