‘Little Couple’s’ Jen Arnold’s Cancer in Remission

The TLC star’s battle with the disease will be documented on the upcoming season of the series

‘The Little Couple’s” Jen Arnold’s rare cancer is in remission.

The TLC star announced the news on Tuesday, which is also World Cancer Day.

“I had my official last chemo treatment,” Arnold told People. “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.”

A TLC representative told TheWrap that her battle with the disease and remission will be featured on the upcoming season of “The Little Couple,” which returns Tuesday, March 4 at 10/9c.

Arnold revealed in December that she had been battling Stage 3 choriocarcinoma, a rare uterine cancer that occurred after she had a failed pregnancy.

“It actually got harder as more time went on,” Arnold says. “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.”

Doctors had to determine the correct chemotherapy dosage levels for a person of her size. Arnold is 3’2”, a result of her dwarfism. In addition to the weekly drugs, she developed pneumonia after surgery to remove a mass in her uterus.

Arnold, 39, is a Houston-based pediatric doctor specializing in newborn infants. She and husband Bill Klein adopted daughter Zoey, 2, and adopted son, three-year-old Will.

“The Little Couple” debuted in 2009 and documented Arnold and Klein, an entrepreneur who recently opened Rockie and Maggie’s Pet Shop in Houston, as they just relocated from New York to Houston for Arnold’s career.
