According to figures provided by the Society, at the 26 public hospitals that offer cancer treatment, the revenue raised by car parking in 2015 totalled almost €16 million, with two hospitals taking in in excess of €1 million, and another two hospitals taking in €1.5 million and €2.9 million respectively.
Donal Buggy, Head of Services and Advocacy at the Irish Cancer Society said: said: “While we acknowledge that car parking is a key source of revenue for many hospitals, the excessive rates charged at some facilities place an unnecessary strain on cancer patients and their families.
"We are asking the HSE to issue guidelines to hospitals, like those that exist in the UK. Introducing free parking for patients undergoing cancer treatment will help ease the burden they face at a time of complex need and financial stress."
The Irish Cancer Society is calling on the public to sign a petition to support their campaign for free parking for cancer patients. To sign go towww.cancer.ie/parkthecharges
