Yeah its a self-made-help article, if you don't know any better this is what you do. It doesn't make it the best choice overall though.

It feels like the guy had a... mediocre GP, got scared by skin cancer diagnosis and over-corrected to most expensive path possible and since stuff was found out we have this article, roughly correct but written in a sensationalist (or freaked out) style. Some claims are outright false (like GPs not knowing heart disease is the biggest killer... really).

Wife is a doctor with overreach between public and private healthcare, and those private services also have their own motivations which aren't often straightforward help-as-much-as-possible, rather milk-as-much-as-possible with tests, scans, long term treatments and so on. Especially CT scans pour non-trivial amount of radiation on the body that on itself can cause cancer down the line.

With public healthcare you at least know primary motivation isn't cash flow but helping patients, the issue is rather overwhelmed resources with limited time per patient. It always depends on individual, as with engineering there are better and worse, yet we all somehow expect every single doctor to be 100% stellar infallible expert with 150 years of experience across all branches of medicine (absolutely impossible for any human being). Look around at your work if you are an engineer and perceive the spread of quality/seniority of each colleague. Same happens in medicine, just stakes are (much) higher.
