"I've been given a really interesting opportunity and one that in a way, I kind of feel blessed," Doherty, joined by her husband, Kurt Iswarienko, and her oncologist, Dr. Lawrence Piro, shared. "Cancer has in a strange way done some amazing things for me. It's allowed me to be more me, like much more in touch with who I am, and much more vulnerable and the person that I always was, but I think it got hidden behind a lot of other stuff."
"My marriage was always fantastic," she continued, "but it's even better now."

BACK TO SLIDE
Having the support of her family and doctors like Dr. Piro means a lot to Doherty.
"I stand here to support every single person who has cancer, and I stand here to also support the husbands and the family that has to go through it," the former Beverly Hills 90210 star said. "Because it's not just the people who have cancer. It's the families too that go through it that it's very hard on."
"I have the easy part," Iswarienko added. "Just being a support system for her... I wish I could do it for her, you know?"
As for what Doherty hopes her fans will take away from her battle with the disease, she says it's all about courage.
"I hope they take away the fact that you have to be strong and put yourself out there and have courage and be a warrior," she stated. "And for me, one of the most important things is for them, their messages, their stories, their love, their support has given me courage. And I thank them for that wholeheartedly."
The actress' positive attitude and legion of supporters appears to be paying off. According to her doctor, she's "nearly finished" with chemotherapy, after starting the treatment in July.
"Shannen is doing amazing," Dr. Piro reported. "We have just a few more weeks of treatment, and then we'll be nearly finished with the chemotherapy."
