The first annual Weekend to End Women's Cancers has raised $3.5 million, making it the largest walk for female cancers in Queensland, organisers say.
More than 1300 walkers began pounding the pavement on Saturday to raise money for the Royal Brisbane and Women's Hospital and the QIMR Berghofer Medical Research Institute.
QIMR Berghofer director Professor Frank Gannon said the money raised would help fund much needed life-saving research programs focused on prevention, diagnosis and treatment of women's cancers.
Prof Gannon said the harsh reality was 50 per cent of Queensland women would suffer from cancer during their lifetime.
"A staggering one in two women in Queensland will be diagnosed with some form of cancer before the age of 85," he said.
Walkers will camp in Everton Park Lands on Saturday night before winding up the 60km trek at Roma St Parklands on Sunday.
