What does the RACGP Red Book say?
For a man aged 50, the benefit is greatest for quitting smoking (24 fewer deaths per 1000 males per decade), which is 10 times the benefit of lowering lipids in a man with metabolic syndrome and 50 times greater than from participating in regular colorectal cancer screening.*
Benefits for women are generally lower, as their baseline risk is lower.*
