Cervical cancer campaigner Lynsey Bennett is hoping to travel to Mexico on Tuesday for specialist treatment.
The 32-year-old, who has advanced cervical cancer, said she is trying to have back up treatment plans to stay alive.
''I plan to stay here for as long as I can. I'm not delusional, but I'm hopeful.'' she said.
Ms Bennett from Ennybegs, Killoe, Co Longford, settled her case against the Health Service Executive this week over the reading of her cervical smear tests.
Ms Bennett, who has two young daughters, had four smear tests between 2010 and 2016, but each time was told they were negative.
She said her cancer was allowed to develop and spread unidentified, unmonitored and untreated until she was diagnosed with cervical cancer in January 2017. In 2018, her cancer returned.
She said she has already planned her own funeral, including hymns, songs and speeches.
She told Ryan Tubridy that she chose Dermot Kennedy's version of Van Morrison's 'Days like this' as her funeral song.
She said she wanted to teach her daughters that "there will be good days and there will be bad days. Even if mammy isn't here to remind you, you put on that song," referring to a conversation she had with her daughters.
She urged women to get smear tests because they saves lives, she said.
