Please describe the minimal age for lung cancer?

There is none...: There is no "minimal age" for lung cancer. It can technically happen at any age. But, since most lung cancer is caused by smoking, usually lung cancer strikes people in middle age or older because it takes time to develop. That said, I have seen plenty of people in their 40s die of lung cancer. It is so tragic. That's why: if you are not a smoker, never start. If you are a smoker, please quit.

None: There is no minimal age. Cancer of any type can occur at any age.

None: "from 2006-2010, the median age at death for cancer of the lung and bronchus was 72 years of age. Approximately 0.0% died under age 20; 0.1% between 20 and 34; 1.1% between 35 and 44; 7.8% between 45 and 54; 19.6% between 55 and 64; 30.5% between 65 and 74; 30.1% between 75 and 84; and 10.8% 85+ years of age" http://goo.Gl/5mixx.
