Feb. 4, 2014 — -- It's great news for Dr. Jen Arnold!

"The Little Couple" star, 39, tweeted today that her cancer is in remission.

"It's official- ME 1 vs CANCER 0... I WIN! Thank you for all the prayers, thoughts, & support!" she said.

This comes after months of chemotherapy treatment to battle the disease.

"What a wonderful way to celebrate #WorldCancerDay! I am done with cancer!" she tweeted shortly after.

"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."

Arnold began chemo in late December. She was diagnosed with stage 3 choriocarcinoma, a rare cancer that formed during a non-viable pregnancy she had in September.
