Input: Consider Input: Question: Does smoking cessation reverse DNA double-strand breaks in human mononuclear cells?
Answer: Smoking induces DSBs in human MNCs in vivo, and importantly, smoking cessation for 1 month resulted in a decrease in DSBs to a level comparable to that seen in non-smokers. These data reinforce the notion that the cigarette smoking induces DSBs and highlight the importance of smoking cessation.
Output: yes
