Lollipop Day is taking place across the country today to raise awareness of oesophageal cancer.
Ireland has one of the highest rates of this form of the disease in Europe.
The lollipop was chosen because difficulty swallowing is one of the first symptoms.
Noelle Ryan, CEO of the Oesophageal Research Fund, explained what the day is all about.
"Lollipop Day is to raise awareness of oesophageal cancer, its symptoms and, through monies raised on Lollipop Day, to support research initiatives."
