Small cell, granuloma, take your pick. The data is available world-wide. The fact is that lung cancer is one from which there is never a good prognosis regardless of type. People can expect 4-5 years on average (although I know people who have gone past ten and have a good quality of life).

It also is one where heredity and genetics plays an enormous role (as opposed to purely environmental conditions).

Like I said, molecular biology is something we've only just noticed far less got a handle on.

Ars Longa Vita Brevis.
