Sausage risk
Risk
21% increase in risk of colorectal cancer for every 50g of bacon daily.
Baseline risk
5 in every 100 get colorectal cancer
21% increase on 5
= 6 in every 100 get colorectal cancer
ie 99 out of 100 unaffected
Which is clear?
• An extra 50g of bacon consumed on a daily basis increases the risk of colorectal cancer by 21 per cent (incidence of 45 per 100,000).
OR• 5 in every 100 men typically get colorectal
cancer in a lifetime. If they all eat an extra rasher or two of bacon every day for life, 6 will.
