MAJELLA O'Donnell has decided to undergo a double mastectomy in order to make certain she stays cancer free.
Majella had previously decided to have one breast removed.
However, her husband, singer Daniel O'Donnell, said she will remove both as a precaution.
"The only thing she has to face now, and this is her own way of facing it, she's going to have a double mastectomy in February and that's her security I suppose, for the future. Preventative," Mr O'Donnell said.
The singer said they had met a woman in a supermarket who revealed that after recovering from breast cancer, it later developed in her other breast.
"The doctors would say that radiation is just as successful you know, that the chances of it coming back in the other breast are, you know, very minute.
"But strangely enough when we were after being at the doctor and getting all that, we went into the supermarket and we met a woman who came over to us."
"The woman spoke to us and she said I'm going through the same thing' and she said 'I had it whatever many years ago' and she said 'this is my second time'.
"She said 'I've got it in my other breast'. And it was almost like an affirmation to Majella that that was the right thing for her to do," he said on RTE's 'The Late Late Show'.
Majella raised €500,000 for the Irish Cancer Society when she shaved off her hair live on the show after being diagnosed with breast cancer this year.
What made her illness harder was that husband Daniel was on tour in the US while she stayed in Ireland for treatment.
The pair were reunited at Dublin Airport this week for the first time since October 26.
They were surrounded by well-wishers when Daniel was invited to cut the ribbon on a new Best of Irish Designs Collection in department store Clerys.
