Shannen Doherty has always been beautiful, but these days, her bravery is making her outright stunning. 

Ever since Doherty made her breast cancer diagnosis public last year, the "Beverly Hills, 90210" actress has continued to share her ongoing battle with the world. Her raw, vulnerable posts — frequently accompanied by the hashtags #TheManyFacesOfCancer and #FightLikeAGirl — have helped humanize a disease that's often a source of fear and misinformation, and her involvement with nonprofits shows she wants not only to get better herself, but to help others heal, too.

Here, we've rounded up some of Doherty's most brave and beautiful moments to come from her fight against cancer. Read on, and prepare to feel inspired.

Most recently, Doherty shared a side of cancer many don't see — the inside of a hyperbaric chamber.

A form of oxygen therapy, hyperbaric chambers are often used for scuba divers to treat decompression sickness. In her caption on Thursday (September 15), she wrote how thankful she was to have a doctor willing to try "out of the box" methods. 

"He saved my skin ... literally," she wrote. "We have many procedures in the future but as long as he's my doctor, I feel safe."

She also advocated that the future of cancer treatment should allow for similar, fully insured methods, giving patients more options.

And after Stand Up to Cancer's fifth annual telethon last week, she reflected that she felt "blessed to be a part of the cancer family tonight and to (have) witnessed such love."

Doherty was one of many celebrities to lend their support as telethon volunteers, with Emma Stone, Bradley Cooper, Tom Hanks, and Celine Dion also in attendance.

The telethon's red carpet was the first one Doherty had walked since shaving her head in July — an experience she also shared with her fans.

Doherty began losing her hair after starting chemotherapy treatments in July. With the help of her mom and a good friend, she made the decision to shave the rest off, and the resulting photo series is as powerful as it is vulnerable.

And she's had some fun with her new look, too!

Her pink locks are reminiscent of Natalie Portman's in "Closer" or Scarlett Johansson's in "Lost In Translation."

She thanked her friends for their support, saying she's realized "vulnerability is something to embrace — not a mask."

From Sara Michelle Gellar to Rose McGowan, Doherty's famous friends have been a constant pillar of support.

And she's offered advice to other cancer battlers in how to choose a doctor.

"He respects that I always come in with new questions, and he takes the time to address and answer all of them," Doherty wrote. "The key is to find a doctor who listens to you and appreciates your concerns."

She encouraged others not to give up their agency just because they're sick, but to feel empowered to question doctors about their treatment, adding "Don't settle."

She shared this extremely intimate photo, showing what it's like to get chemotherapy injections.

And the look on her face makes me really, really want to hug her.

But added it's a lot easier to endure with someone you love by your side.

"I'm blessed to have such a strong support team starting with Kurt (Iswarienko, her husband) who loves me more every second," she wrote in another post. "Can't imagine my life without him. Cancer is not pleasant but it can bring out the best in relationships or the worst. Thankfully, it has made our marriage stronger."

Including when that person is your mom.

Doherty's mother, Rosa, has been a constant source of support throughout her treatment process, proving we're never too old for mom to make things better.

There are still moments when she's scared.

Which, of course, is completely natural.

But ultimately, she strives to stay strong and find silver linings.

"I’ve been given a really interesting opportunity and one that, in a way, I kind of feel blessed,” Doherty told ET in a recent interview. “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.”

And, perhaps most beautifully of all, she hasn't let her own struggles keep her from working to improve the lives of others — especially at-risk animals.

A vocal animal rights activist, Doherty partnered with The Animal Hope and Wellness Foundation — even in the midst of chemo — to bring awareness and aid to abused animals. She's continued to spend a lot of time at their center, snuggling neglected dogs and advocating for their adoption. And the fact that she's taking time out of her own personal trials to protect other vulnerable creatures is moving as hell.
