LONDON:
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.
