Except that no-one knows how many of those 204 (or any of the people that get it but don't die) have actually used sunbeds. It is only one of many factors, including genetics with the biggest risk factor being exposure to the sun (whether you get burned or not), which people can't avoid any more than they can avoid roads making the comparison to RTAs perfectly valid! Not to mention most people who use sunbeds also tend to sunbathe a lot which also increases risk factors.
I know four people who've had melanomas- none of them ever used sunbeds!
The fact that UV light is categorised as a class 1 carcinogen by WHO is irrelavant to the risk levels. There are over 120 things on that list including tap water (because of natural arsenic levels and the risk of long term injestion), red and processed meats, the contraceptive pill and diesel engine fumes.
Yes - sunbeds are a choice (not one I would do by the way - I only have to be in the sun for 10 minutes without factor 50 on and I burn!) but it is a risk people can choose to take, in the same way they can choose to drink alcohol, smoke, take the pill and eat bacon knowing that all of those things could 'potentially' increase their chance of developing cancer.
I fully agree with being clear about risks and making sure people have the right information to make informed choices. But that means being clear about just how significant or not those risks are and not using hyperbole and over inflated statistics without context to spread fear.
You came on a thread where someone, who said they had health anxiety, was in pain and seeking advice, stated made up numbers and over dramatised the risk of metastasis.
Obesity and being overweight are also classed as a preventable cause of cancer and come with double the risk of cancer that UV radiation does - but I doubt you go posting on the weightloss board in the same way.
