The group is encouraging teenagers to develop a monthly routine where they check themselves once a month
Breast Cancer Ireland has launched a new awareness programme that is aimed at girls in Transition Year.
The group hopes that new classroom-based information sessions will help boost breast cancer survival rates in later years.
A clinical nurse will provide girls with information about how to check for symptoms, and they are promoting a new app with information videos and reminders.
The organisation says that 80% of respondents to a survey of 500 young women last year thought that breast cancer would always be a lump or a pain in the breast.
45% are said to have thought that breast cancer could only happen to women over 60.
The organisation's CEO Aisling Hurley says demand for the new education project came from young women who had survived the disease.
She says "if it becomes part of a monthly routine where they check themselves once a month, then they will detect an abnormality if it arises":
