In an exclusive interview with ET in July, Doherty opened up about taking her journey day by day. "I don't look past today," she said. "I want to believe that if I fight, I'm gonna be OK."

"The unknown is always the scariest part," Doherty added. "Is the chemo going to work? Is the radiation going to work? You know, am I going to have to go through this again, or am I going to get secondary cancer? Everything else is manageable. Pain is manageable, you know living without a breast is manageable, it's the worry of your future and how your future is going to affect the people that you love."
