Consultation preparation
- Pathology report and immunohistochemistry if already done.
- Staging imaging in DICOM where possible, plus the written report.
- Operative notes, prior systemic therapy and any previous radiation plan, including dose and volumes if available.
- A named clinical question: curative, adjuvant, salvage or symptom control.
Questions to ask
- Where will simulation and daily treatment take place, and is that the same campus as the consultation?
- Which technique is planned, and why not an alternative already documented on GAF’s cost guides?
- Who owns follow-up after you return home, and what is sent back to the referring team?
- What is the written estimate for the planned course — separate from any consultation fee?
