Arnold, 39, told People.com, "I had my official last chemo treatment. And while I'm hesitant to say I'm cancer-free -- maybe that's common for people who have had cancer -- I'm doing great. Everything is moving in the right direction. I am very excited."
She said the weekly treatments to battle stage 3 choriocarcinoma took a toll, especially while finding the right dosage levels for a person of her size. Arnold has skeletal dysplasia, a bone-growth disorder that causes dwarfism.
"It actually got harder as more time went on," Arnold admitted. "Some weeks were more difficult than others with different side effects. I had a lot of fatigue and nausea and some days it just felt like my hands and feet were very heavy."
She was just thankful for her husband, Bill Klein, and their two young children, son Will, 3, and daughter Zoey, 2. "Bill knows when I'm not doing well and he takes such good care of me. That was huge. That and enjoying watching my children play was a huge uplifting part of my treatment. With kids running around, you don't have much time to feel sorry for yourself."
Dr. Arnold, a neonatologist, has not returned to work full time at Texas Children's Hospital, but is ready to get her life back on track. “Sometimes I get a little winded when I walk around more, and I have that fuzzy chemo brain at times, but I am very excited and happy to be where I am right now. I want to get stuff done. I am anxious to get back to my normal self."
Dr. Jennifer Arnold, star of the TLC show “The Little Couple,” has a reason to celebrate these days. After undergoing intensive chemotherapy treatments to combat a rare form of cancer, she is in remission.
