如果我沒有讀錯的話，Fuz有二十多年的吸煙史（他說從中學最後一年到1997，每天3到5根煙，也就是每周1到1.5包煙）以下是CDC的有關吸煙和肺癌的信息：
According to the CDC, your risk of lung cancer decreases by half within 10–15 years of quitting smoking. However, a 2022 JAMA Oncology study found that former smokers with a history of 20 or more pack-years who quit smoking 15 or more years ago had a 10 times higher risk of lung cancer than non-smokers. The study also found that 40% of lung cancers occurred in former smokers who had quit for more than 15 years.
According to Hopkins Medicine, former smokers still have a higher risk of cancer than non-smokers, but their risk is lower than current smokers. They recommend that heavy former smokers, especially those who started smoking at a young age or smoked for a long time, get annual lung cancer screenings for at least 15 years.
