40,000 people will get cancer this year in Ireland.
The Irish Cancer Society has said the number of cases is increasing - and one in three of us will experience cancer in our lifetime.
Today is Daffodil Day, which, over the last 20 years, has raised over €63m for the charity.
Dr Robert O'Connor is head of research with the Irish Cancer Society.
He is urging people to support Daffodil Day so that vital research to find a cure can continue: “ A lot of our research is engaged with new diagnostics and new treatments, but we are growing our portfolio to better support the needs in terms of newer approaches in prevention, helping support early detection and understanding why people don’t make use of existing screening programmes.
“Developing ways to help people after treatment, helping people overcome some of the really serious symptoms like fatigue.”
