一項大型研究結果顯示，在英國，超重或肥胖逐漸成為致癌一大要因，而因吸煙致癌的病例數正在減少。英國癌癥研究所（Cancer Research UK）發現，約有三分之一的癌癥病例是可預防的。他們還發現由體重超標導致的癌癥所占比率已從2011年的5.5%升至現在的6.3%；而因吸煙致癌的患者數有所下降。

The link between cancer and lifestyle, how much we eat, smoke and exercise is becoming even more stark. The latest data on cancer shows that in 2015, smoking was responsible for more than 54,000 cases of the disease. It remains the most common cause of cancer despite a fall in the number of smokers.

In contrast, the rise in obesity, which is linked to 13 different cancers including breast, bowel and womb, means it is now the second biggest cause of the disease, affecting 22,000 people a year. Too much ultraviolet radiation from the sun or sunbeds, leading to skin cancer, is the third most common cause, with more than 13,000 cases.

Cancer Research UK says that while adopting a healthy lifestyle, stopping smoking, eating a good diet and exercising will not necessarily prevent cancer, it can greatly reduce the risk of developing the disease.

癌癥與生活方式、食量、吸煙量和運動量之間的聯系正變得愈發明顯。有關癌癥的最新數據顯示，在2015年，因吸煙造成的癌癥病例數量超過54,000個。盡管吸煙者數量有所下降，吸煙仍是最常見的致癌原因。

相反，肥胖人群的增加意味著在英國它現在是致癌的第二大原因，每年有22,000人因此患癌，此外，肥胖與乳腺癌、腸癌和子宮癌等13種癌癥也有關。致癌的第三大根源是過多接觸太陽光或日光浴床中的紫外線輻射而導致的皮膚癌，共有13,000起病例。

英國癌癥研究所稱，雖然養成健康的生活方式、戒煙、保持良好的飲食習慣和運動不一定會防癌，但這樣做會大大降低患癌的風險。
