The “Beverly Hills, 90210” star Shannen Doherty has stage 4 cancer and says she’s learning to let go of her material possessions so she can focus on what matters.

On Monday’s episode of her podcast, “Let’s Be Clear With Shannen Doherty,” the actor opened up about clearing her storage units to get rid of things that no longer brought her joy.

“The cancer, for me, has really made me take stock of my life and shift my priorities, and my priority at the moment is my mom,” Doherty said, adding that she knew it’d be hard on her mother if she died first.

The actor said that even though she had high hopes for medical treatments to “keep prolonging” her life, she felt that she “needed to make things clean, just in case.”

Doherty was first diagnosed with breast cancer in 2015 but went into remission in 2017. In 2020, she announced on “Good Morning America” that her illness had returned as stage 4 cancer, meaning that it had spread beyond its original location.

“I don’t want her to have a bunch of stuff to deal with,” Doherty said, referring to her mother. “I don’t want her to have four storage units filled with furniture because I have a furniture obsession.”

The “Charmed” actor said she had “accumulated so much crap” because of her love for antique-furniture shopping and that all the items were just sitting in storage.

“I’m not enjoying it and others aren’t enjoying it, and do I really need any of it? Do I need to have three dining-room tables?” she said. “The answer is no, none of us really need all the stuff that we have, and we could all do with a little bit of downsizing and not be a hoarder, which I was becoming with all my furniture.”

Doherty added that she hoped to sell off all the things she didn’t need so she could have the money to take trips and make more memories with her loved ones.

“I get to take my mom on vacations because I’ll have all this extra money lying around, and I’m not digging into the money in my savings that’s going to make sure everybody in my life is taken care of once I’m dead,” she said.

The 52-year-old said it took time for her to come to terms with the idea of clearing her possessions and the various properties she owned because it felt like she was “throwing in the towel.”

“It feels like you’re giving up on something that was very special and important to you,” she said. “But you know that it’s the right thing to do and that it’s going to give you a sense of peace and a sense of calm because you’re helping the people that you leave behind just have a cleaner, easier transition.”

In the US, about 240,000 cases of breast cancer are diagnosed in women each year and about 2,100 in men, per the Centers for Disease Control and Prevention.

Common symptoms of breast cancer include a hard, painless lump around the breast area, nipple discharge, and dimpling on the breast in a way that’s similar to an orange peel.

While most breast cancers are typically found in women who are 50 or older, cases of it — along with those of colorectal and cervical cancer — in people under 50 are on the rise.

And while researchers don’t know why the rate is increasing, Doherty’s move to declutter her life is typical of — and often helpful for — people who are facing a serious medical diagnosis, two experts told Business Insider.

Dr. Jeffrey Peppercorn, a breast cancer medical oncologist and the director of the Massachusetts General Hospital Cancer Supportive Care and Survivorship Program, told BI he advises his patients to focus on the things in life that are most important to them amid the uncertainty of their prognosis.

“Stage four breast cancer is not curable, but it is treatable, meaning that we can control the disease and prevent it from getting worse, often for years,” he said.

“So ‘decluttering’ your life, whether that means material possessions that you don’t need, closets you have ignored for years, or things that you get stressed over that really aren’t important, can be helpful,” he said.

It’s common for people to realize that certain material possessions aren’t that important anymore, Amy Morin, a psychotherapist and the author of “13 Things Mentally Strong People Don’t Do,” told BI.

“Someone might get rid of their tools as they realize they won’t be restoring that antique car they dreamed about, or they might sell their boat as they no longer imagine a life on the lake where they go fishing,” Morin said.

How decluttering can help

“People with a serious illness often have little control over what’s going on. But one thing they can control is their material possessions,” Morin said. “Selling things, sorting through items, and getting rid of stuff they no longer need may help them feel more in control over something.”

Getting rid of stuff might help someone feel like they’re relieving their families from that burden, too, Morin added.

However, it’s important to note that things can continue to improve, Peppercorn said.
