As Shannen Doherty's breast cancer battle continues, the actress took some time to thank her supportive mother on Instagram.
"Sometimes there's nothing like a mothers love to help get you thru," she wrote alongside a photo of the pair on Saturday. "Thank you mom for always being there and being so strong for me. I love you. #mamarosa #cancersucks #fightlikeagirl."
Doherty told PEOPLE magazine last August that she was "currently undergoing treatment" in her battle with the disease.
A year later, she shaved her head, sharing photos with fans.
In another post this week, Doherty was brutally honest about her treatment.
"Chemo day. A day many of us dread," she captioned a photo of herself under the covers. "Strength gets us thru but every once in awhile, you just want to hide in bed and let chemo day pass you by."
