What is the typical latency period for leukemia after radiation exposure?

• A. 5-7 years
• B. 7-15 years
• C. 10-60 years
• D. 12-20 years

Answer: (A)

Leukemia from radiation exposure tends to emerge within a relatively short window after the exposure. The malignant transformation happens in hematopoietic stem cells in the bone marrow, and these changes can progress to leukemia over several years. The most typical timeframe is about five to seven years after exposure. This shorter latency contrasts with solid tumors, which often develop after longer periods, sometimes a decade or more. So, five to seven years best captures the common onset pattern for radiation-induced leukemia. The other ranges represent longer latencies more typical of solid tumors or less common leukemia timelines, making them less accurate for this specific effect.
