Too many holes.

Lung cancer is an old peoples cancer.
Less than 10 % of lung cancer is found in people under 50.
So they immediately followed a higher risk group. And they followed for 4 years so each year the risk increases.

521 lung cancers out of 77,000...that’s less than 7%
and the “risk” is increased 28 % ? How meaningful is that ?

Actually, it’s even less meaningful than you suggest. Only seven-tenths of 1%.
