Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Tumors are formed when
A
cells are healthy.
B
cells are in interphase.
C
cell division is interrupted.
D
cell division is unregulated.
Explanation: 

Detailed explanation-1: -Overexpression of growth factors or a lack of suppressor proteins can lead to rapid uncontrolled cell division. As cells proliferate without regulation, tumors occur that can become deadly if not treated. Mitosis occurs infinitely.

Detailed explanation-2: -Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Detailed explanation-3: -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.
