There was no hint that her uterus itself was damaged by the radiation, just her eggs.
He didn't say that, no. He told her first that the Eichner radiation caused very serious mutations of her mitochondrial DNA, then told her that the radiation caused massive mutations in her ova such that they were incapable of producing a viable fetus.
I don't think he had to mention the uterus: If the Eichner radiation caused such damage to her ova, how much damage would it have caused to the uterus in which Ian Andrew gestated for 36 hours, 4 hours being the minimum needed to cause said damage? Her fertility problems might well have stemmed equally from the damage to her ova and the damage to her uterus. Ree mentioned oncological complications stemming from the damage--if the problem related only to her ova, then as someone upthread pointed out there's no reason why she couldn't become a mother using donated eggs. The fact that he didn't allow for this possiblility says much, IMHO.
I grant you that there *might* have been damage to the uterus itself - but that wasn't what Ree talked about. Ree talked about the damage to the ova, a damage that prevents Deanna from ever conceiving a healthy child.
I read it as his explaining that the Eichner radiation, demonstrated to cause very serious DNA damage at substantially shorter exposures than Troi's, was responsible for the specific malformations responsible for the malformed fetus.
And conception usually takes place before the uterus even comes into play.
Yes, but the health of the uterus also determines the viability of the pregnancy.
But that's exactly what we're talking about here - I'd have liked the reasons for Ree's suggestion "on screen" so to speak. I'm not the one responsible to make sense of a character's actions, I'd say that's the writers' job.
The only things we have to go from are the radiation damage to the ova, and possible (not even certain!) oncological threats. That's it.
It could have been made more explicitly, I agree, but it doesn't seem much of a strength. Ian Andrew was presumably in Troi's ovary (her only one?) for as long as he needed to retrieve an egg, but he gestated inside her uterus for 36 hours, irradiating it all that time. It doesn't seem plausible to me that a radiation source could cause so great damage to one organ at a relatively brief exposure and then cause so little damage to another with a much longer exposure.
Ree's treatment of the condition suggests that the situation was urgent. Why else would we wake her up in the middle of the night to tell her the cause of her problems and recommend immediate medical treatment? Why would he favour removing presumably healthy, unaffected organs? He did favour hysterectomy when talking of possible oncological complications, but the unknown nature of Eichner radiation makes me think that he was aplying the precautionary principle--better to remove them now than keep them in, for no added benefit to the patient, and risk much more seriious disease. It's not like other forms of radiation damage to tissues doesn't cause cancer. The fact that the damage slipped under the radar for so long might also have caused him to treat this as a sort of ticking time-bomb situation.
As I've said above, the fact that his diagnosis wasn't challenged suggests that his treatment was the medically correct one. There's no reason to believe that Ree was incompetent, or excessively alarmable, or that he was eager to put Troi through unnecessary surgery.
I already mentioned the way my father was told he had cancer: The doctor came in, told him he had cancer - my father just sat there, not really reacting - and that there was nothing that could be done. Then he left, not even asking whether there are questions. Instead he should have sat down, explained the situation, taken the time (I mean he was essentially delivering a death sentence) - and presented options such as palliative chemo therapy, pain therapy. The result was that my father suffered for 3 months the worst pains imaginable, went to some obscure doctors who at least offered some hope... and he died in a way I wouldn't wish on anyone.
That's the difference I'm talking about.
I'm sorry--that's horrible.
What specifically could Ree have done better? Even before learning the root cause of her troubles, Troi was already depressed to the point of not caring whether or not she lived. Ree had to tell her that her reproductive career was definitively over, and that the damage to her reproductive organs was so severe as to merit a hysterectomy.
I agree that waking her up in the middle of the night was probably a bad approach. What else could he have done better?
