The Joey & Rory singer, who is a devout Christian, announced in June (15) that the disease had returned a year after she was initially given the all-clear from cervical cancer.

She underwent surgery for colorectal cancer in July (15) and was said to be doing well, but on Friday (23Oct15), her bandmate and husband Rory Feek revealed the tumours have returned and there is no modern medicine available to her as she treats the aggressive condition.

In a post on the couple's blog, he writes, "Sometimes there just aren't enough surgeries - or doctors - or chemotherapies - or prayers. And you have to wipe the tears from your cheeks and say the words that you were hoping to never have to say... Enough."

Joey, 40, continues, "So we did what you do when the medicine isn't working, and the doctors are at a loss... and when the 'statistics' say you can do more chemo, but it will only buy you a little time... We came home. Not to die. But to live."

Rory admits he is struggling to come to terms with the thought of losing his wife, mother to their one-year-old daughter Indiana, who was born with Down syndrome, but he will continue to hope and pray for a "miracle".

He concludes, "We don't have forever. We've got right now. And that's enough...

"One of the mantras that I always try to live by is to have incredibly 'high hopes, but low expectations', So, even though we know we've reached the end of what medicine can do - and while we prepare for what God has put in front of us... Joey and I will continue to pray for a miracle. We ask for your prayers too. For a miracle. And even more so, for peace with His decision. That is enough."
