Vicky Phelan has been told she will be able to travel home from the US to visit her children this summer.
The cancer campaigner has been receiving an experimental treatment near Washington DC since January of this year.
In recent day the mother-of-two has spoken about how hard she has been finding being away from her two children, Amelia (15) and Darragh (10).
In an Instagram post last night, she said she had asked her doctor is she would be able to visit home this summer.
“I got very upset as I was talking about how much I miss my kids and how I need to see them,” she said. “My poor doctor didn't know where to look.”
“His response was exactly what I need to hear right now; he told me that he will definitely get me home for at least a month in the summer to see my kids.
“I really, really needed to hear that today. I have been struggling over the past two to three weeks because I could not see an end in sight or countdown to a specific date in the future when I would see my kids again.
“At least now I know that I will be heading home sometime in July which is only nine weeks away. I can DO that.”

Speaking to Dermot and Dave on Today FM earlier this week, Ms Phelan said she was originally planning to bring her family to the US for a visit.
“We have kind of changed tack because, if I applied for their Visas and I was refused I’d be devastated,” she said, “I don’t think I could take it at the moment.
“It’s hard enough not seeing them for then to be told, ‘no they can’t come over;’ I think that would break me altogether.
“So, I thought, ‘right what is the easiest way around this’ and the easiest thing is, now that they have lifted the mandatory hotel quarantine for people coming home, is for me to go home.”
She said she expects to be able to remain home for around a month before returning to continue here medical trial.
