How is cell division and cancer connected?

• A. Cancer is caused by fewer cells dividing
• B. Cancer is uncontrolled cell growth and division
• C. Cancer occurs only in bones
• D. Cancer is rapid but orderly division

Answer: (B)

Understanding how cell division is regulated helps explain cancer. Cancer happens when the controls that tell a cell to stop dividing or to die fail, so cells grow and divide without the normal checks. This unchecked growth forms tumors and can spread to other tissues. The other statements don’t fit because cancer isn’t caused by fewer cells dividing, it’s driven by too much, unregulated division. It can occur in many tissues, not just bones. And it’s not rapid but orderly division; it’s rapid and disorganized, lacking normal regulation. So the best description is uncontrolled cell growth and division.
