US actress Shannen Doherty, star of shows such as 'Beverly Hills 90210' and 'Charmed', has revealed her cancer has returned.
Doherty was first diagnosed with breast cancer in 2015, but soon went into remission.
However, the 48-year-old has told Good Morning America that her cancer returned a year ago, calling the diagnosis a "bitter pill".
It is reported that as part of a court battle with an insurance firm, the diagnosis was likely to made public shortly.
Speaking to the show, she said: "It's going to come out in a matter of days or a week that I'm stage four.
"So my cancer came back and that's why I'm here."
She added: "I don't think I've processed it. It's a bitter pill to swallow in a lot of ways.
"I definitely have days where I say 'Why me?' And then I go 'Well, why not me? Who else? Who else besides me deserves this? None of us do'.
"But I would say that my first reaction is always concern about how am I going to tell my mom, my husband."

While working on the reboot of 'Beverly Hills 90210', she kept the news quiet amid the death of former co-star and friend Luke Perry.
She said: "It's so weird for me to be diagnosed and then somebody who was seemingly healthy to go first.
"It was really shocking. And the least I could do to honour him was to do that show. I still haven't done enough, in my opinion. So it's a hard one.
"One of the reasons, along with Luke, that I did 90210 and didn't really tell anybody because I thought, people can look at that, other people with stage four can work too.
"Like our life doesn't end the minute we get that diagnosis. We still have some living to do."
She also revealed that she had support from co-star Brian Austin Green during filming, saying he helped her through.
"I had moments of great anxiety where I thought 'I can't really do this', and Brian was the one person who, of that group of people that knew, that I told pretty quickly and said 'here, this is what I'm dealing with,' she said.
"So, prior to shooting, he would always call me and say 'listen, you know, whatever happens, I have your back.'
"He would look at me and be like 'we got this, kiddo', so Brian helped me through a lot."
On Instagram, the actress posted a photo of Charlie Brown and Snoopy, saying: 'We only live once, Snoopy.
'Wrong! We only die once, We live every day!'
