Colorectal cancer is one of the leading causes of cancer-related mortality worldwide. Cancer screening is known to decrease mortality from colorectal cancer and the measurement of haemoglobin in faeces is an effective means of screening for colon cancer and other lower digestive tract illnesses that are accompanied by bleeding.

In Ireland, almost 3,000 people are diagnosed with colorectal cancer every year. The annual number of cases of colorectal cancer is projected to increase by approximately 100% by 2045 when compared to 2015. The earlier colorectal cancer is detected, it is easier to treat and there is a better chance of recovery or cure. The measurement of haemoglobin in faeces is an effective means of screening for colorectal cancer.
