Shannen Doherty refuses to let the cancer win.
She refuses to stop living her life and making the most of every second, especially when it comes to spending time with her husband.
The latest case in point? Doherty and Kurt Iswarienko celebrated their five-year anniversary in Mexico on Saturday, October 15.
Doherty revealed that she had been diagnosed with breast cancer just over a year ago, in August of 2015.
In August of 2016, meanwhile, she was forced to announce that the cancer had spread.
She explained what happened in an interview with Entertainment Tonight.
"I had breast cancer that spread to the lymph nodes, and from one of my surgeries we discovered that some of the cancer cells might have actually gone out of the lymph nodes," Doherty said at the time.
Since then, the actress has been very open and honest about the difficulty of treatment, sharing photos of herself with a shaven head, in a weakened state.
But she was thankfully feeling good enough to travel this weekend.
And to pet a zebra on her trip!
"5 years ago today I made one of the best decisions of my life,” Doherty captioned the above photo.
“I said ‘I do’ and married my best friend and soul mate @kurtiswarienko. Life has thrown us some huge curves and we have faced them together with strength, love, passion and a desire to stand next to one another thru it all."
"I have learned what partnership truly is with this man. Yes we love to travel and have adventures together like today … hanging out with Vicky the zebra but everyday is an adventure with Kurt regardless of where we are and what we are doing."
The 45-year old added the hashtags "#thisistruelove #anniversary #mexico" to her post.
Doherty also shared the picture at the outset of this article, which features her and her husband wearing sunglasses while standing in front of a row of sculptures.
She wrote as a caption:
"Mexico City. What an amazing place. I’ve been to many spots in #mexico but never here. The food scene is on fire here, history, charm … It’s got it all including childhood memories for @kurtiswarienko who lived here when he was a kid."
As she fights for her life, Doherty is making an effort to remember what's important.
She wrote an emotional message to her mom, for example, and she continues to gush over Iswarienko.
“Our wedding was exceptional and not for the big event it was,” Doherty wrote as a caption recently to a photo from their 2011 nuptials.
“It was exceptional because we committed for better or worse, in sickness or in health to love and cherish one another.”
She concluded at the time:
“Those vows have never meant more than they do now. Kurt has stood by my side thru sickness and makes me feel more loved now than ever. I would walk any path with this man. Take any bullet for him and slay every dragon to protect him.
"He is my soul mate. My other half. I am blessed.
We send Doherty our best wishes for a full recovery.
