It's Breast Cancer Awareness Month and one woman's diagnosis, more than a decade ago, has led to millions of pounds being raised for hospitals.
Glennis Hooper, who set up the charity Crazy Hats Breast Cancer Appeal in Northamptonshire, was a headteacher when she was diagnosed with cancer 14 years ago.
The charity has raised more than two million pounds for breast cancer care in local hospitals.
At Kettering General, hundreds of thousands have gone towards state-of-the-art equipment and finishing touches to make patients feel more at home.
And outside hospital - a different kind of treatment - free therapy sessions for patients and their carers.
The services the Crazy Hats Breast Cancer Appeal provide are so popular the charity's now looking for a bigger base.
It hopes it can keep supporting people with breast cancer for decades to come.
