Jennifer Arnold: Her cancer is in remission

U.S. reality TV personality Dr. Jennifer Arnold says her cancer is in remission after months of weekly intensive chemotherapy treatment. "I had my official last chemo treatment," the 39-year-old neonatologist and star of "The Little Couple" told People.com Tuesday. "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." The married mother of two young children was diagnosed with stage 3 choriocarcinoma last year. Arnold, who has dwarfism, underwent surgery to remove a mass in her uterus, then began chemotherapy after a bout of pneumonia.
