You are referring to cancer prevention, while the GP is referring to cancer treatment.

I'm not sure I follow. Screening detects cancer that is already there, hopefully in early stages when it might be treated more easily. In both cases, cancer is already present.

Treating infectious disease than can cause cancer (H. pylori, HPV) has nothing to do with cancer treatment.

Treating, for example, thyroid or prostate cancers that would not have killed the person improves cancer survival statistics but nothing else.

I included that as a PS specifically because they don't change overall numbers much. Yes, it's true some cancers are becoming less common, but ~50% of the population get's cancer it's very common even if the numbers are shifting around slightly.

Thanks for clarifying what you intended when you meant screening, which is differentiated from screening for cancer itself, which is how I read your upthread comment "[s]ome nipped a potentially fatal cancer in the bud".
