Clinical Oncologists of Reddit, how is the technical aspect of a consult like?

We all know navigating doctor-patient relationship is a huge part of oncology, but I'm not talking about that. I want to know what type of medical thinkling you do when defining a therapy. Is it "just" a question of matching cancer subtype to specific drug? Are there puzzle-solving aspects or complex medical decisions (purely on the medical side, naturally every decision in oncology is multidimensional and very complex)? In short, is it an intelectually stimulating specialty on the pharmaceutical-physiological side?
