blood cancer research

Anyone can take part. Whether you walk 1km, 10km, or 40km you’re helping to fund life-saving blood cancer research. And you won’t be walking alone!

Together we can beat the deadliest blood cancers

We're a community dedicated to beating blood cancer. We do this by funding research and supporting those affected. Since 1960, we've invested over £500 million in blood cancer research, transforming treatments and saving lives.

More people are surviving cancer than ever. But if you're diagnosed with one of the deadliest blood cancers, your chances are just 1 in 3.

That’s why every step counts this October. Every kilometre you walk represents one person diagnosed with blood cancer, and every pound you raise will help fund life-saving blood cancer research. So, join the challenge today and together we can beat the deadliest blood cancers.

“Walking in the countryside helped me cope with the death of my husband”

Denise took part in Walk the World after her husband sadly died from acute myeloid leukaemia (AML), one of the deadliest blood cancers, just 5 years into their marriage.

“What started as tiredness, back pain and an unusual yellow tongue quickly became every family's worst nightmare when a blood test revealed my husband had no immune system. The next day, he was diagnosed with AML.

He endured three rounds of chemotherapy and a stem cell transplant, with his 26-year-old son donating his stem cells. The treatment was horribly gruelling, and sadly he died one year after being diagnosed in July 2021.

I chose to take part in Walk the World because walking in the countryside has helped me cope with losing my husband just five years into our marriage. I wanted to raise money for Blood Cancer UK to fund research into kinder, more effective treatments for people facing blood cancer in the future.”
