That is bloody horrible news for Ruben & and close ones - hope they can stay strong through this.

Let’s hope that not only it has been discovered early enough, but also treatments are available, and can be successful.
I’m sure Ruben will do wonders for helping raise cancer awareness, given his position in the public eye.
The odds are all people are close to someone who has battled, is battling, or will battle cancer in their lifetime - whether family, friend, or even themselves.
The financials of cancer treatment, however, depend on numerous factors – the medical system of country of residence (Netherlands for Ruben), level of health insurances & life insurances, treatment type required, location of treatment (he is in the USA at the moment), duration, types of medications etc.
In Australia, cancer treatment is quite different depending on what you can afford – and no, even the best private health insurance does not cover all cancer treatments. Private health does not cover the drugs… and they are the expensive part, if you need the latest and greatest.
Pharmaceuticals in Australia are either covered by the Pharmaceutical Benefits Scheme (PBS), or they’re not. Only certain drugs are subsidised, and therefore, if you want the latest and greatest, you need swathes of cash – and these drugs can range from a few grand per vial, to $100,000’s for a round of treatment.
It’s nice to think we all get the best treatment possible, but that is far from the truth – it’s user-pays, and if you’re not cashed-up, guess what? Bog standard treatment for you.
So lets leave the pontification regarding Ruben's medical expenses at the door, and wish the man the best of luck with whatever treatment he requires.
