Why doesn't cancer simply die off after a single rogue cell division?
A
Cancer cells lack the ability to divide more than once due to limited energy resources.
B
Cancer cells are immediately recognized and destroyed by the immune system after one division.
C
Cancer cells require the presence of viruses to survive after the first division.
D
Cancer cells acquire mutations that allow them to evade normal cell death mechanisms and continue dividing uncontrollably.
Verified step by step guidance1
Understand the nature of cancer: Cancer arises when cells acquire mutations that disrupt normal regulatory mechanisms, allowing them to grow and divide uncontrollably.
Recognize the role of mutations: Mutations in genes such as oncogenes (which promote cell division) and tumor suppressor genes (which inhibit cell division or promote cell death) enable cancer cells to bypass normal controls.
Explain evasion of cell death: Cancer cells often acquire mutations that allow them to evade apoptosis (programmed cell death), a mechanism that typically eliminates damaged or abnormal cells.
Discuss immune system evasion: Cancer cells can also develop mechanisms to evade detection and destruction by the immune system, allowing them to persist and proliferate.
Summarize the key point: Cancer cells do not die off after a single division because they acquire mutations that enable them to evade normal cell death mechanisms, continue dividing, and resist immune system attacks.
