Anastacia felt "so betrayed by medicine" when she received her cancer diagnosis

Speaking on the 'Turning Points' podcast, she told 'Shout' hitmaker Lulu: "I felt so betrayed by medicine. And when I say that I mean how doctors approach you as a woman is - do you have breast cancer in your family? And I go 'Mum?' No, we don't. Ok great.

"And they let it go.

!But when I hear the stats of women with breast cancer, 70% of those women with breast cancer is not genetic so why ask me and then toss it aside when the smaller amount of breast cancer is genetic and the bigger amount is unknown.?

"Like, that's the bigger number so shouldn't we pay attention or give some knowledge.

"And they're like - 'Well it's really hard as doctors because we can't tell you what not to do.'

"We can't tell you that it's food, we can't tell you that it's air, we can't tell you that it's stress, we can't tell you that it's anything particular, it's probably all of that, but it's definitely happening at a wider range than it is genetic.'

"So I'm like great, I'm going to talk about it."

The 'Left Outside Alone' hitmaker underwent treatment for the disease in 2003 and was given the all-clear but it returned a decade later and she opted to have a double mastectomy.

Asked what the biggest turning point in your life so far has been, she said: "I would say probably the first cancer because it came out without me wanting it to come out. It was released the day that I found out. It was leaked. So it was leaked and they asked me for a statement and I was like - what do you mean a statement, is that real? Do people give statements? I thought that was a joke. And I was like - I don't even understand how to give a statement. So before I was able to tell Elton or tell my friends, or tell anyone that I was positive let alone know if I would die, what stage, what anything, they were going with it, so whatever, whatever I said is in the news I guess or whoever they put together and then it was like chasing it from then on."
