They divide uncontrollably and can invade surrounding tissues.
B
They are unable to survive outside their tissue of origin.
C
They undergo apoptosis more frequently than normal cells.
D
They only divide when growth factors are present.
Verified step by step guidance1
Understand the definition of cancer cells: Cancer cells are characterized by their ability to divide uncontrollably, bypassing the normal regulatory mechanisms of the cell cycle.
Review the concept of invasion: Cancer cells can invade surrounding tissues, which is a hallmark of malignancy. This ability distinguishes them from normal cells.
Clarify apoptosis: Apoptosis is programmed cell death. Cancer cells often evade apoptosis, allowing them to survive and proliferate longer than normal cells.
Examine growth factor dependency: Normal cells typically require growth factors to divide, but cancer cells can often bypass this requirement, enabling uncontrolled division.
Compare the options provided: Evaluate each statement against the characteristics of cancer cells. The correct answer should align with the hallmark traits of cancer cells, such as uncontrolled division and tissue invasion.
