Radiation Appointment Duration

Great question! Understanding what to expect can help you plan your day. Here's what typically happens:

Initial Consultation/Planning Appointment

Duration: 1-2 hours
This is your first visit where the radiation oncologist:
- Reviews your medical history and imaging
- Explains the radiation plan
- Answers questions about side effects and what to expect
- May do a physical exam

Simulation/Planning Session (if needed)

Duration: 30 minutes to 1 hour
The team creates a detailed map of where radiation will be delivered
You'll be positioned on the treatment table and may have imaging done
Marks or tattoos may be placed on your skin to ensure accurate positioning

Actual Treatment Appointments

Duration: 15-30 minutes total
- Setup and positioning: 10-15 minutes
- Actual radiation delivery: 1-5 minutes (varies greatly by treatment type)
These are typically daily appointments (Monday-Friday) for several weeks
The actual radiation is painless and silent

Factors That Affect Timing:

Type of radiation (standard vs. advanced techniques like IMRT or proton therapy)
Your cancer location and stage
Whether imaging is done during treatment
How many fields need to be treated

💡 Pro tip: Arrive 10-15 minutes early to account for check-in time.
