"Little Couple" star Jen Arnold seemed to be in good spirits as she celebrated the Christmas holiday with her family. Despite revealing she was diagnosed with cancer, the reality star posted pictures of her son Will playing with Christmas toys and posing with Santa. She also shared several snapshots of the meal she cooked for her family. 

"Cancelled chemo= feeling better for holiday=energy for baking Christmas cookies with kids & @ReallyBillKlein- Life doesn't get much better!" she wrote on Twitter.

The 39-year-old reality star announced that she was battling stage 3 uterine cancer in early December to People magazine. Arnold revealed that the cancer was caused by a non-viable pregnancy from August and had spread to her lungs.

She told the magazine that she was surprised to discover she was pregnant in August but when she went to the doctor for an ultrasound the baby didn't have a heartbeat. The embryo was removed but cells left behind sparked the aggressive cancer.

"There are moments I feel just terrible," she told People. "I can't believe it's happening. Other times, I feel like this is just a bump in the road."

Immediately after the diagnosis Arnold started chemotherapy but the cancer did not respond and grew four times its size. Doctors also discovered that the disease had spread to her lungs. Recently, the TLC star underwent a hysterectomy to help combat the disease.

"We wanted to avoid surgery in her case because of her shortened airway and the difficult she has had n the past with surgeries," Dr. Concepcion R. Diaz-Arrastia from Baylor College of Medicine said. "But we felt we had no choice. The disease was not responding to chemotherapy. We had to do this in order to save her life."

Despite her health problems, Arnold and her doctors are remaining positive about the prognosis and her battle with cancer will be shared on future episodes of the TLC reality show "Little Couple."
