In one, posted about a year ago, she's showing off a bikini in a fitness show. In the second, she's bald from chemotherapy — but still smiling.She explained that she hasn't given up her enthusiasm for fitness — or any of her passions. "Thankfully, we have caught it in enough time that I am still able to fight and can kick ovarian cancer's ass and be in remission one day, hopefully soon," she wrote. "I still go to the gym, I still laugh, cry, sing (horribly), and just enjoy each and every second of every single day."
