Let's use real numbers shall we? https://seer.cancer.gov/statfacts/html/colorect.html https://seer.cancer.gov/statfacts/html/colorect.html Approximately 4.3 percent of men and women will be diagnosed with colorectal cancer at some point during their lifetime, based on 2012-2014 data. Your chance (roughly) goes from 4.3% to 5% if you eat bacon (and salumi, prosciutto, etc) regularly. Whether or not you personally consider this small or large, it seems like a pretty straightforward cost/benefit analysis.
