Is it normal to get Brain Scans if experiencing headaches?

[Freakzilla]

Hi Guys,

My girlfriend has been experiencing headaches for a while now. They aren't getting any worse. She is on Zoladex and Tamoxifen.

We've just been to see her oncologist and they have booked a head and neck ct scan. They said if they come back clear they then request MRI Scan. The reason for CT first is that it's quick to get a CT Scan.

Am I right in thinking this is common protocol if you tell your oncologist you've been experiencing headaches.

My girlfriend is beside herself, but I said it's a process of elimination to find out what the problem is.

Thanks
