30 percent of women diagnosed with breast cancer in Ireland are aged between 20 and 50.
At the start of Breast Cancer Awareness month, women of all ages are being urged to be breast aware and to look out for signs of the cancer.
Speaking to 98FM, Aisling Hurley, CEO of Breast Cancer Ireland, said: One of the main concerns we have is that while Breast Check is fantastic in that it offers free mammograms to women over the age of 50, we are seeing that high proportion of younger women being diagnosed. So it is really important that younger women are more breast aware and that they go and routinely look, particularly from the age of 40, to have their mammogram done.'
Women can download the Breast Cancer Ireland app to learn how to check themselves properly and get a monthly reminder to do so.
Breast Cancer Ireland will host The Great Pink Run in the Phoenix Park on October 13.
