If you give a doctor enough time with you in a hospital he will kill you most assuredly. I rank oncologists as the most prolific profiteers purveying their glorified rat poison.
I’ve never poisoned any glorified rats (badoom tish)
Now, now... modern cancer treatments, rat poison and all, CAN slow down if not stop most cancers.
But again maybe the patients do not live longer; it’s only being miserable that makes it seem longer.
I watched my dad perish of multiple myeloma 3 decades ago. The doctors already warned he would succumb, that they could only slow it down for a while. And the medications did knock each flare-up down, until it finally came back with a vengeance that nothing touched. Not a pleasant fate to contemplate, but I still might choose to buy time with the medicines that be.
Sometimes though, they actually cure people. Whether their treatment caused the cure is debatable of course.
My oncologist saved my life. But, in truth, he was an a hole in dealing with patients. I dealt with his assistant, who was an angel from God. She totally protected me.
