Anastacia reveals the terrifying menopause symptoms that she thought were caused by a brain tumour

US pop star Anastacia has revealed the terrifying moment she thought she had a brain tumour. 

Speaking on The Project on Monday night, the singer, 56, said she was shocked to discover she was actually experiencing menopausal migraines.

Anastacia went on to explain she had been self-diagnosing and had ‘no idea’ that her symptoms, which included exhaustion and brain fog, were ‘hormone-related’. 

‘It was really really scary, but I’m not scared to talk about it… Menopause has not been easy,’ the noughties icon told The Project hosts Waleed Aly and Sarah Harris on Monday. 

‘What’s been the hardest thing?’ Harris asked. 

‘Everything. I had every side effect that I had no idea that I had. I didn’t really know what was wrong. My SVT (supraventricular tachycardia) came back. My heart palpitations,’ she explained.

The singer, 56, said she had no idea she was actually experiencing menopausal migraines 

‘I thought I had a brain tumour. I was not in a good place towards the end and then realised that I had no numbers. ‘So I was like “Oh, okay. Well give me some numbers kids. Give me progastrin”.’

Anastasia joined the program to promote the upcoming Australian leg of her 25th anniversary tour of her debut album, Not That Kind. 

‘I am wearing my low rise jeans on tour,’ Anastacia said as she explained her enduring commitment to Y2K fashion staples. 

‘You never know with my age and the mesopause situation, we might fluctuate between sizes on the tour.

‘I went through a period of wanting to eat everything in the refrigerator and now I’m on bioidenticals girl, so you know how it is,’ she told Sarah. 

Bioidentical hormone therapy (BHRT) for menopause involves using hormones that are chemically identical to those naturally produced by the body. 

Sarah praised the singer’s ‘good attitude’ about her health struggles, to which Anastacia replied: ‘I don’t like the side of winging and moaning.’

Anastasia has previously suffered from an abnormal heart rhythm, and was diagnosed with Crohn’s disease at 13.

The pop icon was also diagnosed with breast cancer in 2003, aged 34, and then again a decade later.  

Last month, Loose Women fans were left moved by Anastacia’s two-word verdict on her cancer battle that involved 16 surgeries.

While chatting to Christine Lampard, Brenda Edwards, Coleen Nolan and Jane Moore, her health came up. 

Anastacia said: ‘When I got it the second time I decided to do the mastectomy, that means it’s all gone.

‘I made a very, very hard choice early and the minute the surgery was complete, I never worried about it again. 

‘I did have 15 more surgeries  after that surgery to get to where I was complete, but who cares?’

She poignantly signed off: ‘I won!’

Anastacia is heading Down Under for the time in a decade as part of a world tour celebrating 25 years of her hit debut album, Not That Kind.
