Jen Arnold's cancer in remission, 'The Little Couple' mom reveals

Neonatologist Dr. Jen Arnold, who stars with her husband, Bill Klein, on TLC's reality show "The Little Couple," said Tuesday that the cancer she revealed publicly in December is now in remission.

"I had my official last chemo treatment," Arnold, 39, told People magazine. "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."

Arnold said the chemotherapy treatments "actually got harder as more time went on."

"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," said Arnold, an attending neonatologist at Baylor College of Medicine and the medical director of the Simulation Center at Texas Children's Hospital, both in Houston.

The first symptoms of what was diagnosed as stage 3 choriocarcinoma appeared while she and Klein, 39 -- who was raised in Port Jefferson Station and graduated from Comsewogue High School there in 1992 -- were in India to pick up newly adopted daughter Zoey, 2.

She began bleeding. After contacting her OB-GYN, she flew home while Klein stayed with their adopted son Will, 3, to complete Zoey's paperwork.

Her husband, she said, "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."

The physician, whose dwarfism was caused by the bone-growth disorder skeletal dysplasia, has not yet returned to work. "Sometimes I get a little winded when I walk around more and I have that fuzzy chemo brain at times," she said, "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."
