Obesity& Cancer

Cancer Research UK found more than a third of all cases of cancer were avoidable - some 123,000. The charity similarly found that surplus weight now instigated 6.3% of all cancer cases - up from 5.5% in 2011 - while smoking as a root had declined.

Cancer Research UK found the country with the greatest amount of preventable causes of cancer was Scotland with 46.5%, followed by Northern Ireland on 37%, Wales on 37.9%, and England on 36.3%.

Across the UK, smoking endured by far the leading cause of avertible cancer, although it dropped from 18.4% in 2013 to 14.7%.

The standard way of identifying if someone is obese is by calculating their body mass index (BMI). It trials whether you're a fit weight for your height. A BMI of more than 25 means you're overweight and a BMI of more than 30 means you're classified as obese, while there are some exceptions. Cancer Investigation UK found overexposure to UV radiation began about 13,600 cases of melanoma skin cancer a year - or 3.8% of all cancer cases. Other preventable causes of cancer comprised drinking alcohol and eating too little fibre, it said. However, overall the analysis found the part of preventable cases of cancer had fallen - from 41.3% in 2013 to 33.7%.
