Scottish lung cancer rates rise for women over 40 years

Thu, 03/20/2014 - 14:35

Lung cancer rates in women have almost doubled in Scotland over the past 40 years, according to Cancer Research UK.

Cancer Research UK said the number of females diagnosed with the disease had climbed 97% since 1975, reported BBC.

Although more men still die from lung cancer there has been a 40% drop in the rate among males over the same period.

The charity said the figures reflected smoking trends in the UK, with the number of male smokers falling from the 1950s.

It was not until two decades later that the number of female smokers began dropping significantly.

Lung cancer is the most...

New evidence links smoking to postmenopausal breast cancer risk

Wed, 03/19/2014 - 11:20

Postmenopausal women who smoke or have smoked in the past may have an increased risk of breast cancer compared with women who have never smoked according to a new study published in the British Journal of Cancer.

Researchers from the U.S. National Cancer Institute in Bethesda, Maryland found that postmenopausal women who reported they smoke were 19 per cent more likely to develop breast cancer compared with women who never smoked.

And those who said they were former smokers were seven per cent more likely to be diagnosed with the disease than women who had never smoked.

These results held true even after accounting for alcohol consumption, which is known to increase...

Gamers decode half a year of Cancer Research UK’s genetic data in one month

Mon, 03/17/2014 - 08:35

In one month ‘citizen scientists’ have analysed DNA data that would have taken a scientist six months to analyse by eye by playing Cancer Research UK’s new smartphone game Play to Cure: Genes in Space.

If this amount of DNA – tightly-coiled strings of genetic information – was unravelled it would stretch across 40 miles, or (65 km). Incredibly, this is a distance equivalent to the length of more than 540 football fields, or about 80 times the...

Lifestyle interventions can improve health outcomes in patients at risk of colorectal cancer

Thu, 03/13/2014 - 16:30

Direct interventions in diet and physical activity among patients at risk of colorectal cancer can lead to significantly improved weight reduction, helping tackle a major risk factor for the disease, a new study led by the University of Dundee has shown.

Obesity is a recognised risk factor for colorectal and other cancers. Recent UK estimates on cancer preventability indicate that 47% of colorectal cancer can be prevented through attaining a healthy body weight, appropriate levels of physical activity and dietary fibre intake and reductions in...

Researchers capture 'most complete' picture of gene expression in cancer cell cycle

Mon, 03/10/2014 - 08:10

Uncontrolled cell growth and division is a hallmark of cancer. Now a research project led by the University of Dundee has provided the most complete description to date of the gene activity which takes place as human cells divide.

Researchers have managed to gather data which details the behaviour of protein molecules encoded by over 6000 genes in cancer cells, as they move through the cell cycle. The team has used advances in technology and data analysis to study how genes work over time in cancer cells, as opposed to capturing a `snapshot’ of activity – a leap forward they describe as akin to `...
