Swinder: You wanna remove her hippocampus?
Derek: One of them. It's a common procedure for seizure patients
Swinder: Moving her hippocampus could compromise her memory, her speech, she wouldn't be able to practice medicine anymore.
Derek: I have performed this surgery hundreds of times.
Swinder: On cancer patients?
Derek: No. But it's...
Izzie: If you do the surgery I could lose my memory?
Derek: It's unlikely but it's possible.
Izzie: And, if you don't do the surgery...
Swinder: We could shrink the tumor with IL2.
Izzie: If the tumor doesn't kill me first.
Derek: Why take the chance?
Swinder: Have you even done a WADA test to see how her memory would be affected?
Derek: Putting her brain to sleep and asking her to remember a bunch of flash cards is not an accurate assessment of the post surgical outcome.
Swinder: But, it would tell us whether or not she could function afterwards. And, as Dr. Stevens primary physician...
Derek: Fine I'll do it. It's unnecessary but...
Swinder: The surgery is unnecessary.
Derek: The tumor is already symptomatic, she's having hallucinations.
