I only read the headline and not the article, so I'm not sure if this was mentioned. Would the main cause be from melanoma caused by UV? Melanoma rates in Australia went through the roof when we had that big ozone hole above our country.

Definitely. I'm an electrician, so my eyes are usually drawn to these type of things. Light fittings, outlets, switches, etc.

Tell that to the bar I was at last night in Palermo. They had a string of festoon lights going down the laneway and every one of them was incandescent. I noticed the same in Taormina. In fact, Italy seems pretty far behind the rest of the EU when it comes to environmental concerns.....but that's for another thread.
