Is pituitary tumor surgery risky?

Yes: Yes. This gland sits in a bony bowl behind and between the eye balls. Find a specialized center and a neurosurgeon that treats these commonly.

Not if done well: Pituitary surgery is tricky but common and well defined. A competent surgeon should be able to give you his statistics of risk, but should also be positive about the benefit to risk ratio. Surgery to the brain is never without risk. However, now with microscopic computer guided and video monitored techniques, the risks have decreased quite a bit.
