I haven't come across a statistic for that treatment plan tho' someone might have guesstimated something. I wanted to know what the odds of recurrence are if one declines radiation and chemo and anti-hormone drugs but two oncologists told me that there are no really reliable statistics for that and that no such can be done because of medical ethics and law. That is, once a treatment is proven to be, by and large, beneficial, it would be a violation of U.S. law and ethics to create a study where a significant number of participants agree NOT to take that treatment.
