Most types of cancer can be put down to bad luck rather than risk factors such as smoking, a study has suggested.

A US team were trying to explain why some tissues were millions of times more vulnerable to cancer than others.

The results, in the journal Science, showed two thirds of the cancer types analysed were caused just by chance mutations rather than lifestyle.

However some of the most common and deadly cancers are still heavily influenced by lifestyle.

And Cancer Research UK said a healthy lifestyle would still heavily stack the odds in a person’s favour.

Ebola patient Pauline Cafferkey is receiving an experimental anti-viral drug and blood from survivors of the disease, doctors in London have said.

Specialists at the Royal Free Hospital in Hampstead, where the nurse is being treated, did not name the drug.

Dr Michael Jacobs said Ms Cafferkey was in isolation and was sitting up in bed, talking and reading.

As the disease has no known cure and is unpredictable, Dr Jacobs said they would know more in a week’s time.

He said Ms Cafferkey had agreed to all the treatments and her family had been to see her.

West Africa’s Ebola epidemic has cruelly exposed the weaknesses of health systems in the countries where it struck. It was understandable that they were not prepared for Ebola, which has never been reported in the region before, but the director of the World Health Organization (WHO), Margaret Chan, says what they lacked was a robust public health infrastructure to deal with the unexpected.

“This requires good background data on the usual,” she says, “so that the unusual stands out. [It means] making good quality care accessible and affordable to everyone, and not just to wealthy people living in urban areas; having enough facilities available in the right places with enough well trained staff and uninterrupted supplies of essential medicines; diagnostic capacity that returns rapid and reliable results; and information systems that pinpoint gaps and direct strategies and resources towards unmet needs.”

A healthcare worker returned to Glasgow, Scotland this Sunday from Sierra Leone and has been diagnosed with Ebola. The patient has been transferred to a specialized care unit at the Royal Free Hospital in London.

More than four in 10 cancers – 600,000 in the UK alone – could be prevented if people led healthier lives.

Latest figures from Cancer Research UK show smoking is the biggest avoidable risk factor, followed by unhealthy diets.

The charity is urging people to consider their health when making New Year resolutions.

Limiting alcohol intake and doing regular exercise is also good advice.

According to the figures spanning five years from 2007 to 2011, more than 300,000 cases of cancer recorded were linked to smoking.

A further 145,000 were linked to unhealthy diets containing too much processed food.

Obesity contributed to 88,000 cases and alcohol to 62,200.

Sun damage to the skin and physical inactivity were also contributing factors.

Sierra Leone has declared lockdown of at least three days in the north of the country to try to contain the Ebola epidemic reports BBC World News

Shops, markets and non-Ebola related travel services will be shut down, officials said.

Sierra Leone has already banned many public Christmas celebrations.

More than 7,500 people have died from the outbreak in West Africa so far, the Word Health Organization (WHO) says, with Sierra Leone the worst hit.

Sierra Leone has the highest number of Ebola cases in West Africa, with more than 9,000 cases and more than 2,400 deaths since the start of the outbreak.

The other countries at the centre of the outbreak are Liberia and Guinea.

State of emergency
Alie Kamara, resident minister for the Northern Region, told AFP news agency that most public gatherings would be cancelled.

“Muslims and Christians are not allowed to hold services in mosques and churches throughout the lockdown except for Christians on Christmas Day”, he said.

No unauthorised vehicles would be allowed to operate “except those officially assigned to Ebola-related assignments” he added.

The lockdown would operate for at least three days but this could be extended if deemed necessary, officials said.

Sierra Leone has been in a state of emergency since July.

The outbreak began a year ago in the West African country of Guinea, but only gained international attention in early 2014.
