I would do what Trapper says...at least arm yourself with alternative actions. Knowledge.
My nephew was diagnosed with thyroid cancer in the fall. The family wouldn't even consider a conversation about anything other than the MDs recommendation which was, surgery to remove. In less than a week, they went into surgery. I also kept hearing words like 100%, which the family was told by the surgeon. 100% recovery. 100% of his patients were still alive after 10 years. 100% everything.
So, during the surgery the parathyroid was damaged which came back as "ops, it happens sometimes." He can now barely speak. He has been propelled into a suite of new problems now, and the 100% has been replaced by these 'complications' which has taken on new language like "part of the recovery". He has radioactive iodine pumped into his body to destroy the thyroid cells that spread into his lung area. The first round was not as successful as they had hoped. Ops. The 100% has now been replaced by a potential 3 rounds of this procedure, to get to 100%. My brother is having to revise his language to the family each time which is very stressing because he has several problems on his plate now - how he communicates to: his son; his family; the extended family; and the doctor which I am now starting to hear things like "not telling us everything", etc etc etc.
And on it goes.
Hey, I am not at all adverse to medical science saving lives. My sweetie and I know this intimately. Not all doctors are bad, terrible, evil. They have motivations driven by training and backgrounds like everyone else. But I would arm myself with knowledge because there are too many possibilities for historical 'ops' to become the norm. This is hard as hell, harder, when a loved one is suffering, or worse. I want it gone, I want out out, now. But these decisions made now are likely irreversible. Knowledge knowledge knowledge.
