linked to changes in recreational or holiday exposure to UV rays (including sunlight and sunbeds). 7,8 Liver cancer, though rare in the UK (age-standardised rates are 7 per 100,000 males and 3 per 100,000 females) is the second fastest increasing cancer in males and the fourth fastest in females (increases of 40% and 30%, respectively, in the last decade). Cirrhosis of the liver (caused by excessive drinking, viral infections or inherited diseases) is a major risk factor for this cancer. 9 Kidney cancer is the fourth fastest increasing cancer in males and third fastest in females (age-standardised rates have increased by 26% and 31%, respectively, in the last decade). Established risk factors for kidney cancer include cigarette smoking and obesity. 10-12 Prostate cancer is the third fastest increasing cancer in males, with age-standardised rates rising by around a third (32%) in the last decade. The use of PSA testing for prostate cancer will have contributed to the marked increase in new diagnoses of this disease. 13,14 While thyroid cancer is the fastest increasing cancer in females, with the age-standardised rate rising by more than two-thirds (68%) in the last decade, it has a small disease burden (5 per 100,000 females). Increased breast cancer incidence (and subsequent treatment) may explain some of the increase. 15 Another rapidly increasing cancer with a small disease burden in females is mesothelioma , which is not among the 20 most common cancers, but the age-standardised rate (1 per 100,000 females) has increased by 44% in
