It's incredible but also kind of sad. The cynic in me knows he'd be gone by now if his money and celebrity didn't afford him cutting edge treatment. I wish all sufferers had that option.
This isn't how cancer treatments work. It really pains me to see this take that somehow rich folks can buy their way out of cancer in every single thread relating to it. We are not NEARLY a rich family by any means, but my father had access to some of the best cutting edge cancer treatments available. Only because his specific markers lined up with this experimental treatment, and agreed to be part of the study. It was still just chemo (in a pill) with intense targeted radiation. It still didn't buy us much (or any) time.
If you don't know, chemo is essentially poison that wrecks shop on your body in hopes that it takes some of the cancer along with it. Radiation is similar in that it wrecks all of the human parts to take some of the cancer with it. Cancer treatment is one of the most brute-force types of medical treatment we use today, because we simply don't have better options.
But if it makes you feel better to dump on a rich guy with cancer, go for it.
