The 39-year-old pop star has opened up about her fight with the disease for the first time since announcing she had advanced-stage breast cancer in August insisting she is being as "brave" as she can be in her fight against the illness.
Taking to Instagram, she wrote: "Hi everyone. Thank you so much for all the messages of love and support that I've received since my last post.
"Everyone has been so kind and reading your comments and DMs has been such a huge source of strength to me.
"I can't deny that things are tough right now but I'm fighting as hard as I possibly can and being as brave as I know how."
The former Girls Aloud singer also revealed she has written a book about her life, which has given her a "positive" focus while she's having to stay at home "in between" hospital visits.
The memoir will be called 'Hear Me Out' and will be out shortly after Christmas.
She said: "In September the lovely people at Ebury Publishing asked me if I would be interested in writing a book about my life story.
"It came at such a good time for me as it's given me something fun and positive to focus on while I've been stuck at home in between trips to the hospital for treatment.
"I've nearly finished it now and this week Mum and I have been looking though old photos choosing which ones to include.
"It'll be out after Christmas and I'm really proud of it. I hope you'll like it. Sending lots of love to everyone – I hope you're all keeping well - S x"
Over summer, Sarah revealed she has been diagnosed with breast cancer earlier in the year, which then spread to other parts of her body.
She said at the time: "There's no easy way to say this and actually it doesn't even feel real writing this, but here goes.
"Earlier this year I was diagnosed with breast cancer and a couple of weeks ago I received the devastating news that the cancer has advanced to other parts of my body.
"I'm currently undergoing weekly chemotherapy sessions and I am fighting as hard as I possibly can.
"I understand this might be shocking to read on social media and that really isn't my intention.
"But last week it was mentioned online that I had been seen in hospital, so I feel now is the time to let people know what's going on and this is the best way I can think of to do so."
