Ms Hayes will undergo brain surgery to remove up to 90% of the tumour this week and then start chemotherapy and radiotherapy.
“The rest [of the tumour] is in part of my brain they think they are going to leave because that’s too dangerous to get out,” she said.
“So there will be a little bit left that we treat with chemotherapy and radiotherapy and it’s going to be a rough year probably,” she said.
Ms Hayes said she had since written a will and was now dealing with what she termed her “brain tumour admin” ahead of her operation.
“As a mum you don’t want to leave a mess behind if things go south,” she said.
“You want to leave everybody OK.”
