Shannen Doherty is in the fight of her life, but she's got plenty of allies in her corner —including her mother, Rosa. The 45-year-old actress recently sent her mom a sweet message of thanks for the love and care she's been giving her during her grueling cancer battle.

The former "Beverly Hills, 90210" and "Charmed" star shared a tender black-and-white shot of Rosa cradling her like a child.

"Sometimes there's nothing like a mothers love to help get you thru," Doherty wrote in the photo's caption. "Thank you mom for always being there and being so strong for me. I love you."

Doherty was diagnosed with breast cancer in March 2015. The actress underwent a single mastectomy, and revealed recently that the cancer had spread to her lymph nodes. She's now undergoing chemotherapy treatments.

Doherty has shared each step of her journey with fans on social media. In July, she posted photos that documented her shaving off her long dark hair while her mom and her model pal Anne Marie Kotright comforted her.

Doherty's close-knit support group also includes her husband, Kurt Iswarienko, and longtime pal Sarah Michelle Gellar of "Buffy The Vampire Slayer" fame.

Gellar recently shared a photo of the two actresses to honor Doherty's courage and candor.

"My #mondaymuse (and really every day #muse) is my brave friend @theshando," wrote Gellar in the photo's caption.

"I've always said she is one of the most loyal friends I've ever known, and now while she is facing the toughest journey of her life, she is sharing it with friends she has never met in the hopes of helping other people who are going through the same struggle."

"That's a true friend," wrote Gellar.
