Lifestyle change can prevent thousands of cancer cases

The other major preventable lifestyle behaviours include drinking alcohol, reducing exposure to ultra-violet (UV) radiation, air pollution and eating good amount of fibre

  • Few lifestyle changes can prevent cancer
  • Leaving habits like smoking, etc. can help
  • environmental factors like air pollution are also responsible for cancer

Getting rid of smoking tobacco, exercising and shedding weight may be key lifestyle behaviours that can cut down thousands of cancer cases a week, say researchers, including one of Indian-origin.

The other major preventable lifestyle behaviours include drinking alcohol, reducing exposure to ultra-violet (UV) radiation, air pollution and eating good amount of fibre.

Following these can prevent nearly four in 10 cancer cases in the UK, says the Cancer Research UK, a non-profit, in a paper published in the British Journal of Cancer. The study showed that more than one in 20 cancer cases could be prevented by maintaining a healthy weight.

“Leading a healthy life doesn’t guarantee that a person won’t get cancer, but it can stack the odds in your favour. These figures show that we each can take positive steps to help reduce our individual risk of the disease,” said Harpal Kumar, chief executive at the Cancer Research UK.

According to the World Health Organisation, cancer is the second leading cause of death globally, and is responsible for 8.8 million deaths in 2015. Globally, nearly one in six deaths is due to cancer.

The latest figures, calculated from 2015 cancer data, showed that tobacco smoke caused around 32,200 cases of cancer in men (17.7 per cent of all male cancer cases) and around 22,000 (12.4 per cent) in women in the UK.

Around 22,800 (6.3 per cent) cases of cancers including bowel, breast, womb and kidney, a year are down to being overweight or obese.

“The research clearly demonstrates the impact of smoking and obesity on cancer risk. Prevention is the most cost-effective way of beating cancer,” Kumar said.

“Obesity is a huge health threat right now, and it will only get worse if nothing is done. Banning junk food TV adverts before the 9 p.m. watershed is an important part of the comprehensive approach needed,” said Linda Bauld from the non-profit.

In addition, overexposure to UV radiation from the sun and sunbeds causes around 13,600 cases of melanoma skin cancer a year, while drinking alcohol, eating too little fibre caused around 11,900 and 11,700 cases respectively. Outdoor air pollution was responsible for around 3,600 lung cancer cases a year. IANS

Air Pollutants Can Be Stopped If They Are Frozen : Scientists

The air-quality across the NCR was very poor

Freezing pollutants can prevent deadly outdoor air pollution — thought to cause more than three million premature deaths worldwide every year — from seeping indoors by 99 per cent, scientists have discovered.

The research, by a team of scientists from the Nottingham Trent University in the UK and the Chinese Academy of Sciences, involved studying the effectiveness of cryogenics for indoor air purification, by removing the gaseous pollutants and tiny particulates caused by haze.

The team found that as they circulated haze-polluted air through a cryogenic condenser, the finer particles stuck together in the condenser tube before dropping out by gravity, and emerging as clean air.

Their method was able to remove 99 per cent of particulates and 98 per cent of nitrogen oxide pollutants.

“Hazardous outdoor air pollution has severely affected indoor air quality, threatening the health of billions of people,” said Professor Robert Mortimer, Dean of the School of Animal, Rural and Environmental Sciences at Nottingham.

“Outdoor air pollution in cities is a global problem. While there are some existing technologies to purify indoor air, they can be inefficient, expensive or produce harmful by-products.

“When outdoor air quality is poor, people tend to spend even more time indoors – but outdoor pollution also leads to indoor pollution and people are still impacted.”

The experiments, reported in the journal Science of the Total Environment, showed that by simply circulating polluted air through a small freezing chamber we can remove most of the fine particles and gas pollutants.

“Our study makes it possible to add an ‘air cleaner’ option to household appliances in areas which might experience extremely poor air conditions. By controlling indoor air pollution and improving air quality in this way, this work could be greatly beneficial for public health,” added Gang Pan, Professor at the varsity.

It is hoped that the work could pave the way for simple modification of air conditioning and humidifier units so that they can also clean polluted indoor air, the team said.

Delhi and the National Capital Region (NCR) on Sunday witnessed “very poor” air quality with the minimum temperature recorded at 12.4 degrees Celsius, two notches below the season’s average.

The air-quality across the NCR was very poor, according to System of Air Quality and Weather Forecasting And Research.

The humidity at 8.30 a.m. was 87 per cent. The maximum temperature was likely to hover around 28 degrees Celsius. (IANS)
