How do you feel doctors should approach the “potential”

Diseases, conditions. I know that most have to save their asses and make the parent aware. But after doing my own research, I am a bit upset at my pediatrician for giving me a “diagnosis, but not really cause we can’t know until a neurosurgeon looks at it” that has me freaked out. I feel like they should tell the parent that there is cause of concern, but that further testing will identify or rule out certain conditions.” He threw out “hydrocephalus” like it’s a light word. I’ve been crying every night and driving myself crazy as to how my child will be. I’ve found so many articles about how this could benign or extraaxial fluid. I am researching but feel that maybe my pediatricians Gould this have jumped the gun with “hey, I think it’s this. This is the course of treatment that those children usually have.”
