This report presents statistics on the National Bowel Cancer Screening Program for Australians invited to take part between July 2008 and June 2011. Just over 800,000 people were screened in that time, with about 60,000 found to require further assessment. One out of every 11 colonoscopies performed for further assessment detected and removed an advanced adenoma (pre-cancerous lesion), and a cancer was detected in 1 out of every 33 colonoscopies. However, this represents only a partial picture of outcomes due to incomplete reporting.
