Treatment for glioblastoma (GBM)

Meet Karla


My name is Karla Harris. I'm coming to you to talk to you about my best friend, Optune.

So I had my head shaved yesterday. I'm a little nervous but very excited to be participating in a program that's going to help not only me, but other people in the future.

My responsibility in all of this is essentially we're going to walk through everything piece-by-piece and get you all really comfortable with the equipment and the device. When you are ready, I'm going to have you initiate treatment. So do you see your blue TTfields? You are officially on Optune.

Hey everybody. It's day two of the Optune. I was so worried at first and kind of scared I suppose when they put them on about how hard it might be and how difficult of a challenge it would be. But it's not a problem at all, and today, I have some new hats to try on to wear over my Optune when I go out. And I did go out with a scarf on over the Optune today and no one really looked at me funny or pointed fingers or laughed at me. It went quite well.

I just want to let you all know how important this is today. Because today, at the doctor, we found out this is the only active treatment I can use at this point against the brain cancer. It's been a great experience. I've been able to lead my normal everyday life—all my community meetings and activities. Thank you very much.
