Emma Stone says her mother's cancer diagnosis was "terrifying".

The Amazing Spider-Man actress was devastated when her mom Krista Stone was found to have triple negative breast cancer in 2008 and although she was living in Los Angeles at the time, Emma flew home to Arizona as much as possible while Krista underwent treatment.

She told People: "I was oddly stoic, the opposite of how I usually am. But it was terrifying."

Despite Emma's fears, Krista has been cancer-free for five years following a double mastectomy and chemotherapy and praised her daughter for her bravery.

She said: "I'm sure, in private, Em lived in fear and anxiety. But she really shifted into this [mode of], 'We're going to take care of this, and everything's going to be fine'."

Emma, 24, is extremely close to her mother and has previously credited her for telling her what to avoid wearing when growing up and giving her confidence.

She said: "When I was a teenager and all the cool girls were wearing their pyjama pants in school, my mother would forbid me to do that - or to let my bra straps show.

"Everybody has parts of their body that they dislike, but I'm not going to lose any sleep over them."
