Earlier this month we shared the unfortunate news that the star of TLC's "The Little Couple," Jen Arnold, revealed she has stage 3 choriocarcinoma, a rare type of cancer.
The reality TV personality gave fans an update of her ongoing battle via a Twitter photo she shared Friday.
Arnold snapped the pic during her second day of inpatient chemo therapy. She recently said the visit was originally scheduled for last week but was cancelled when doctors discovered she had a low blood count.
In addition to being a TV star, Arnold, 39, is a pediatrician based out of Houston, Texas. She and her husband, Bill Klein, have two adopted children from China and India.
"The Little Couple" first aired on TLC in 2009. The show follows the life of Arnold and Klein, who are both under four feet tall. The series wrapped up its fifth season in October.
