The former "Beverly Hills 90210" star posted on Instagram Thursday a photo of herself in a pink wig and her husband, Kurt Iswarienko, playfully touching her nose.
"I'm blessed to have such a strong support team starting with @kurtiswarienko who loves me more every second. Can't imagine my life without him," she continued. "Cancer is not pleasant but it can bring out the best in relationships or the worse. Thankfully, it has made our marriage stronger."
"Cancer is like a book with so many pages you don't see a way to read through all of them at once. But when you take them one page at a time, a story emerges and takes shape in unexpected ways," Iswarienko wrote on his own Instagram page.
He continued, "The outcome isn't clear or easy to reckon with, but you find as you go through the journey that a clear outcome isn't the point. The journey is the thing. The people you connect with along the way are the point. It's about human energy. It's about breathing. #shannensquad."
