Nunya at a tomotherapy session for her nasal tumor.Tomotherapy is a type of radiation therapy used on dogs.  It delivers the radiation in slices instead of a beam.  Nunya had 20 sessions to complete her tomotherapy treatment.  To start the treatment off, a CT scan was done and the oncologist took a few days to map out how the dosage would be delivered.

From these posts, we heard an amazing story about a horse going through tomotherapy in the same machine pictured to the right. Click here to see Breezy, the horse, undergoing tomotherapy treatment.  Breezy had a rare tooth root cancer and helped pioneer radiation tomotherapy treatment on horses, thanks to the doctors at A&M.

As with all forms of radiation treatments, there are side effects.

Radiation Burns:

Nunya showed no signs of radiation burns until the very end of her treatment.  She started losing a few chunks of skin directly under her eyes after the last week of tomotherapy treatment started.  These spots grew in size and redness for a good three weeks.  During that time they  blistered and looked extremely painful but Nunya was always great about allow us to put the burn cream on her face.
