Actor Stanley Tucci has opened up about being treated for cancer three years ago.

Known for his roles in such films as 'The Devil Wears Prada' and 'Captain America: The First Avenger', or more recently 'Supernova', Stanley Tucci discussed the previously-undisclosed diagnosis in an interview with Vera Magazine.

The actor was diagnosed with a tumor at the base of his tongue.

He told Vera: "It was too big to operate, so they had to do high-dose radiation and chemo.

"I'd vowed I'd never do anything like that, because my first wife died of cancer, and to watch her go through those treatments for years was horrible."

Tucci's wife Kate died of breast cancer in 2009 when she was 47.

The couple had been married since 1995.

They had three children together, twins Nicolo and Isabel and daughter Camilla.

"The kids were great, but it was hard for them," Stanley Tucci said in the interview. "I had a feeding tube for six months. I could barely make it to the twins' high school graduation."

The actor also said that the cancer is unlikely to return (according to the Vera article, he said this while "touching wood with both hands")

He also spoke about how: "[cancer] makes you more afraid and less afraid at the same time.

"I feel much older than I did before I was sick. But you still want to get ahead and get things done."

Stanley Tucci currently stars in the 9/11 drama 'Worth' opposite Michael Keaton on Netflix.
