More than 33,000 people are being diagnosed with invasive cancers every year, new figures have shown.
A report from the National Cancer Registry shows that more people than ever before are being treated.
The rising number is due to ageing and growth of our population, the organisation says, while rates of cancer 'appear to have stabilised or even fallen recently'.
The latest figures show around 9,000 people are dying from the disease annually - with lung cancer being the biggest killer.
However, the five-year cancer survival rate has increased to 61%, while there were an estimated 167,700 cancer survivors alive in Ireland at the end of 2015.
Professor Kerri Clough-Gorr, Director of the Registry, explained: “Some individual cancers (for example melanoma and female lung cancer) continue to show worrying increases in incidence and mortality rates.
"As the population grows and ages, and treatment and survival improve, the population of cancer survivors — now estimated to be almost 170,000 people — continues to grow."
