When Clare Taylor first adopted her horse, Frankie, she knew there was work to do. Frankie hadn't been well looked after, and needed a lot of training.
But despite all the work Clare was putting in, the eight-year-old mare suddenly began reacting to her new owner a little strangely.
Every time she went near Frankie, the horse would repeatedly nudge the right side of her chest, near her shoulder. After a while, it started to get sore - and that's when Clare noticed a lump.
It was confirmed as Grade 3 triple negative breast cancer.
She then began six months of chemotherapy - which finished last year - and also had a double mastectomy after discovering she had the BRCA mutation, which is linked to a range of other cancers too.
But thanks to Frankie, the cancer was caught early. Clare is now a year out of treatment and doing well.
Across the UK, someone is diagnosed with cancer every two minutes.
In Warwickshire and the West Midlands, it's three people every hour. But thanks to research breakthroughs over the last 40 years, survival rates have doubled.
And people like Clare have a better prognosis than ever before.
She is now supporting Cancer Research UK, helping to promote World Cancer Day through the charity's 'Unity Bands' and fundraising towards future research.
"Years ago, someone with my diagnosis wouldn't have had anywhere near the outlook I have now," she said.
"I'm so grateful for all the work they do. Hopefully, the research will continue and maybe - if my kids have got the BRCA gene too - things will be even more positive for them."
