Agreed, this part was oversimplified. Sicker, more complex patients will have multiple interacting conditions, and choosing the right course of action is often not trivial (this is why we have medical school and residency). I think if you talk to physicians in different specialties, they will also argue that their disease of interest is as complicated as cancer. Also, if you were to look at UpToDate (the clinical guidelines used by physicians), you would be hard pressed to find any diagnosis with a single treatment for all patients. Nothing in medicine is simple.
