Shannen Doherty has thanked her mum for helping her in her battle with breast cancer.

The former Beverly Hills 90210 star shared a touching image on Instagram of herself with her head in her mother Rosa's lap.

She wrote: "Sometimes there's nothing like a mother's love to help get you thru.

"Thank you mom for always being there and being so strong for me. I love you."

Shannen added the hashtags #mamarosa #cancersucks #fightlikeagirl.

The 45-year-old actress revealed that she was fighting breast cancer in August last year, after being diagnosed in March.

She has been documenting her fight on social media, recently sharing a set of images of herself shaving her head.

In another recent post, Shannen opened up about going through chemo.

"Chemo day. A day many of us dread," she said.

"Strength gets us thru but every once in awhile, you just want to hide in bed and let chemo day pass you by."
