1 Risk of skin cancer following phototherapy for neonatal jaundice: retrospective cohort study David H Brewster, 1,2 Janet S Tucker, 3,4 Michael Fleming, 1 Carole Morris, 1 Diane L Stockton, 1 David J Lloyd, 3,4 Sohinee Bhattacharya, 3,4 James WT Chalmers 1,2 1 Information Services Division, NHS National Services Scotland 2 University of Edinburgh 3 University of Aberdeen 4 Aberdeen Maternity Hospital Colorectal Cancer Study Day Stirling 13 September 2012 How Scotland compares to other countries

2 Outline Risk factors Mortality Incidence Survival

3 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

4 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)
