Further treatment will be needed, she said, such as immunotherapy - but she won't undergo chemotherapy.
However, the fitness star is determined to remain positive. 'I don't want to feed any negative energy and I want to keep positive because I also think I'm a role model for other people,’ she told the publication.
'I just think the mind is a really strong thing and it's really important to keep positive and try and focus on the good things.'
Two weeks ago Jacqui confirmed she had been diagnosed with the tumour. The star was previously diagnosed with a stage four melanoma on her back in 2017 after her sister noticed an unusual mole on her shoulder.
Speaking about the tumour in her head, the bodybuilder said: 'I'm really p*ssed off, but what can you do about it? Just got to roll with the punches don't you, not just cry about it?'
Jacqui discovered the lump in her head by accident last month and after getting a second opinion was told she had a malignant tumour.
“I was doing my hair one morning and I thought ‘oh, I’ve got this lump on my head. It was around early February,” she said.
“I went to the doctor who said it was just a cyst and that it was fine and not to worry about it. Then I went to my skin doctor in Byron and he did a biopsy then two days later he said ‘you’ve got a malignant tumour’.
“So I was straight in for a CT scan and then I went to a specialist who said ‘I’m not going to touch you until you’ve had a pet scan’, which I had last Friday.
‘The result of that is that it hasn't spread which is great. Their concern now is whether it's a primary or secondary - they're going to operate ASAP,' she said.
Despite the diagnosis, Jacqui says she has no plans to slow down and hopes to enter a bodybuilding competition after surgery.
