We are often told that being overweight increases our risk of cancer. In fact, in the UK, obesity is the biggest preventable cause of cancer after smoking, according to Cancer Research UK. But why does being overweight increase a person’s likelihood of developing cancer? A group of scientists say they now know. The team from Trinity College Dublin say the reason overweight people are at greater risk of developing cancer is because a certain cell in the body that’s used to destroy cancer gets clogged with fat and stops working as a result. Publishing their findings in the Nature Immunology journal, the team said they were able to show that the body’s natural cancer-fighting cells get clogged by fat. They are hopeful that new drug treatments can be developed that will reverse the effects and restore the cancer-killing ability of said cells. Until then, though, the best advice remains to stay a healthy weight, stop smoking and cut down on alcohol. Speaking about the findings of the research, Dr Leo Carlin, from the Cancer Research UK Beatson Institute, said: “Although we know that obesity increases the risk of 13 different types of cancer, we still don't fully understand the mechanisms underlying the link. “This study reveals how fat molecules prevent immune cells from properly positioning their tumour-killing machinery, and provides new avenues to investigate treatments.” [Related reading: Major study finds eating processed meat raises risk of breast cancer]
A new report from Public Health England (PHE) shows that smokers who take advantage of local support services and stop smoking aids, like e-cigarettes, inhalers and nicotine patches, stand a much greater chance of successfully kicking the habit. Quitting smoking using willpower alone, often referred to as ‘going cold turkey,’ only works for a small number of people who try it, with just 4% remaining smoke-free after 12 months. Nevertheless, of the six in 10 smokers in England who want to quit, the majority try to do so using the cold turkey method. But by turning to a combination of local support services and nicotine replacement therapies, smokers could witness much better success, according to PHE. In fact, PHE says that 51% of smokers who utilised local support services successfully quit and this figure rose to 63% for those who incorporated an e-cigarette or similar into their efforts. To further boost the stop smoking drive in England, PHE has created the Stoptober campaign. In addition to increasing awareness about the most effective ways to quit smoking, the campaign also has its own free online personal quit plan. This plan provides personalised stop smoking advice based on a smoker’s answers to three quick questions. There’s even an official Stoptober app to help smokers stay on track and get stop smoking advice while on the go. The Stoptober campaign centres on three really good reasons to kick the smoking habit: feel healthier, save money and protect your family – can’t really argue with that!
