Risk factors / protective factors (1)
Family history and inherited conditions• Familial adenomatous polyposis (FAP)• Hereditary non polyposis colorectal cancer (HNPCC or
Lynch syndrome)• Ashkenazi Jewish background
Other medical conditions• Ulcerative colitis• Crohn's disease• Diabetes mellitus• Acromegaly• PMH of large bowel cancer, endometrial cancer,
testicular cancer, or lymphoma• PMH of cholecystectomy• PMH of organ transplant

Risk factors / protective factors (2)
Diet• Red and processed meat increase risk• Fruit, vegetable, fibre decrease risk• Calcium may reduce risk
Other factors• Age• Excess weight increases risk• Alcohol probably increases risk• Smoking (long-term) may increase risk• Physical activity decreases risk• Aspirin (and other NSAIDs) probably decrease risk• HRT and OC may decrease risk• Vitamin D may decrease risk• Screening reduces risk of dying from colorectal cancer
(and endoscopic screening reduces incidence)

Our statistics on incidence, survival, and mortality, and on the prevalence of lifestyle risk factors suggest that we can
So how does Scotland compare to other countries, and can we do better?
