I just wanted to say that the staff at the Oncology Center were amazing. A special shout out to Lauren, to Cara, and Deborah. Those girls made my transition. Having radiation every day, they made it a lot easier, a lot smoother. They always had a smile. I am just so flabbergasted that there are still people out there that look after individuals who are going through traumatic times. So I really appreciate the whole team at the Oncology Center. And tomorrow is my last day. Yay!

The CT scan had to be done twice because the oncologists felt more area needed to be scanned as a result of me having surgery to remove my esophagus the first time through. The radiologist was very empathetic to the extreme discomfort I was going through during the scan and review process and kept me updated all the way through. As soon as she got the call that the scan was approved, she came in to complete her remaining tasks and permit me to get my arms out of a most uncomfortable position.

Every radiation tech that worked with me, over the 5 weeks I was going, was GREAT!!! They all were knowledgeable and friendly. They explained everything and worked very well together. I was very comfortable through all my treatments. The only problem is wait times to get back to get my treatment. There were only 4 treatments that I was taken back on time. That is a problem. But all the techs that worked with each day were GREAT!!!
