Shannen Doherty introduced her Instagram followers to the radiation machine that she refers to as "Maggie."
"I've seen Maggie five days a week for what seems like forever. We have a love hate relationship," the 45-year-old actress captioned a photo on Wednesday of herself posing with the machine. "I love her because she's part of the life saving treatment I'm receiving. It's astounding how far we have come with technology."
Doherty -- who is currently battling breast cancer -- added that she hopes one day Maggie will be out of a job. "Maggie will be retired and the cure will be found. Things like immunotherapy are the future," she continued. "But for now, it's me and Maggie."
Last month, the TV star was honored with the Courage Award at the American Cancer Society's inaugural Giants of Science Gala, and told ET that she was accepting the award on "behalf of every single cancer patient out there" for their "courage."
"Courage isn't something that comes to you immediately," Doherty said during her acceptance speech. "It's not something that you have fully. Courage is something that you gain and it grows. Courage is facing every day and every obstacle one step at a time. Courage is knowing that fear is not going to find a solution; it's not going to help you find a cure. Courage is embracing what you're going through and trying to get through it with as much dignity as you possibly can, while also accepting your circumstances and allowing yourself to feel everything."
