How to reduce cancer risk
There are many known risk factors for cancer. It has been estimated that smoking is responsible for 30% of all cancer deaths and that one-third of cancers can be linked to diet, obesity and lack of exercise.
Risk reduction is taking action to lower one's risk of developing cancer. Risk can be increased or decreased by lifestyle choices and the kind of environment a person lives and works in. About half of all cancers can be prevented through healthy living and policies that protect the public.
