The 39-year-old singer was diagnosed with breast cancer last year and was told later on that the cancer had spread throughout her body, meaning that she 'won't see another Christmas', according to a new book she has written about her ordeal called Hear Me Out.
In closing that book, she wrote: "Before I put this book to bed, I wanted to share a little bit of positive news.
"MRI scans at the end of December revealed that the tumours in my brain and in my lung have shrunk a bit with the treatment."
She added: "I don't know exactly what this means for me, but at least I know it's moving in the right direction, and right now, every little victory feels momentous.
"With this news under my belt, I was able to enjoy a relaxing quiet Christmas with mum and yes, I got plenty of lovely Christmas pressies."
That said, she also wrote in the book about how she was told by doctors that this year's festivities could be the last that she enjoys.
In an extract printed by The Times, Harding said: "In December my doctor told me that the upcoming Christmas would probably be my last."
The Manchester-born musician said that she wants to be in 'comfort' and 'pain-free', and doesn't want an exact prognosis.
She said that she is 'trying to live and enjoy every second of my life, however long it might be'.
Harding explained: "I am having a glass of wine or two during all this, because it helps me relax.
"I'm at a stage now where I don't know how many months I have left.
"Who knows, maybe I'll surprise everyone, but that's how I'm looking at things."
Harding also revealed that she had suffered from sepsis during a stay in hospital and had to be placed into an induced coma, as well as on a ventilator.
She explained: "Even once I was off the ventilator, I couldn't speak properly,
"All I could do was make noises that sounded like a chimpanzee trying to communicate."
The star has previously spoken about her 'scary' decision to go public with her diagnosis in August 2020, but says that it has proven the 'right thing to do' and added that she has been 'inundated' with support from the public, as well as from her former bandmates.
She added: "I'm grateful beyond words for that."
