What is RapidArc?

Why do I need a CT scan for radiation?  I just had one recently at the hospital.

Can you tell what is happening with the cancer by these x-rays?

What is a boost?

How many weeks will my treatments last and how long does each treatment take?

Can I miss a treatment? Will it affect my outcome?
 

I feel fine. Why do I have to see the doctor every week?
 

Will I have the same treatment time every day? What if I have a doctor’s appointment or an appointment for chemotherapy?
 

Will I start radiation today? How soon can I start radiation? 
 

I have an oncology doctor and surgeon at another facility, but would like to get radiation therapy treatments at The Cancer Center, since that is closer to my home. Is this OK?
 

What if I have outside x-rays and studies?
