The claim, cancer data based on incidence are better than mortality ist
right:
1. Not all cancers are lethal so these were missed in an analysis based on
mortality data only.
2. Data based on mortality include progress in curing cancer and can pretend
a decrease in cancer incidence when no decrease happend or even an increase
occurred..
This is not so important when lung cancer is an issue, because lung cancer
is rarely curable. About 90% of the diseased do not survive the next 5
years.
