We've got a number of working cures and preventions for cancers, just not most types and many are not 100% reliable. I'm happy to complain about pharma and we've still got a long way to go, but this is a bad take. Yes, they've "allowed" it for years. (Did you get your HPV vaccine already?)
+1 - cancer prognosis used to be treated as a death sentence for most forms of cancer and "stage 4" was almost immediately referred to hospice. Amazing progress in our lifetimes, and an impressive roadmap ahead.
As I understand about the HPV vaccine: It only prevents new infections. It does not cure existing infections. And you need to get it very young to reduce chances of infection before vaccine.
