Chapter 16, Problem 21PDQ
Radiotherapy (treatment with ionizing radiation) is one of the most effective current cancer treatments. It works by damaging DNA and other cellular components. In which ways could radiotherapy control or cure cancer, and why does radiotherapy control or cure cancer, and why does radiotherapy often have significant side effects?

Radiotherapy (treatment with ionizing radiation) is one of the most effective current cancer treatments. It works by damaging DNA and other cellular components. In which ways could radiotherapy control or cure cancer, and why does radiotherapy often have significant side effects?
Suppose you discover a new gene called ABC that contributes to the efficiency of DNA damage repair. You have noticed that cells carrying mutations in this gene stop dividing and go into senescence. Do you think that mutations in this gene can cause cancer? Briefly explain your answer.
What separates cancer cells from normal cells?
Describe one form of mutation that can increase the risk of a normal cell being cancerous.
