One in four women in Ireland will develop cancer in their lifetime, with breast cancer, colorectal cancer and lung cancer the most common cancers in women. Cancer is more likely in older women, with only 18% of cancers in women occuring before the age of 50. To reduce the risk of cancer, women can stop smoking, be physically active, reduce alcohol intake and eat a balanced diet.
