Blood test could detect serious skin cancer spread

 A simple blood test could be used to identify patients whose skin cancer has spread, according to a presentation at the National Cancer Research Institute conference.   Melanoma is particularly difficult to detect and treat once it spreads.   Dundee University researchers say that measuring levels of a gene called TFP12 in DNA in the blood could be key.   Cancer Research UK said the findings could lead to faster diagnoses and new treatments.   Dr Tim Crook,...

France issues rabies warning after kitten's death

French authorities are warning of a rabies threat after a cat died of the disease, previously thought to have been eliminated from the country. The two-month-old black and tan kitten was found last Friday in Argenteuil, near Paris. It died three days later. France's Ministry of Agriculture has begun an investigation and vaccinated five people as a precaution. France was declared free of rabies in 2001 but a dog imported from Morocco infected other dogs in 2008. "It is...

Breast cancer 'rising in under-40s' across Europe

Cases of breast cancer in women under 40 are rising across Europe, research suggests. Experts say it is unclear whether this is due to improved diagnosis or new risk factors. A study in Cancer Epidemiology found cases rose by about 1% a year between 1990 and 2008 in seven countries. Breast cancer is the most common cause of cancer among women globally, and the leading cause of cancer death. Cancer in young women is rare - only about 5% of all breast cancers are in women under the...

Patient in vegetative state 'paid attention' to sounds

A patient in a vegetative state was able to pay attention to sounds in his surroundings, a study found. An analysis of brain activity in 21 patients and eight healthy volunteers showed one of the patients could pick out individual sounds. The University of Cambridge researchers say the finding marks an advance in understanding levels of consciousness in vegetative patients. The team hope to develop better ways for some patients to communicate. A vegetative or minimally conscious...

HIV antibodies 'have potent impact'

A potential new HIV treatment has a "profound and unprecedented" impact on the virus, according to animal studies published in the journal Nature. Potent antibodies were able to wipe a hybrid of human and monkey immunodeficiency viruses from the bloodstream of monkeys within days. The findings could "revolutionise" the search for an HIV cure, say experts. The US researchers said trials in patients with HIV now needed to take place. The immune system produces...

Seven classes of breast cancer test 'offers new hope'

 A test that identifies seven classes of breast cancer could be available within two years, say UK scientists.   Writing in the British Journal of Cancer, the Nottingham researchers say it could help doctors tailor treatment better and boost survival rates.   Currently, two biomarkers are routinely screened for in breast tumours.   Last year researchers revealed that breast cancer can be divided into 10 different forms of the disease based on a patient's genetic...

Gardening 'linked to longer lives'

Pottering around the garden or fixing up the house has been linked to a longer life in a study of people over the age of 60. Older people can struggle to exercise vigorously, but the study said simply getting off the sofa and avoiding a sedentary lifestyle was a lifesaver. The Swedish study of 4,232 people suggested the risks of heart attack and stroke were cut. The findings were published in the British Journal of Sports Medicine. The researchers at the Karolinska University...

Saturated fat pledge 'a drop in the ocean'

A pledge by food manufacturers to cut saturated fat levels is "a drop in the ocean" in the fight against obesity, a top public health expert has said. Morrisons, Subway and Nestle are among firms signed up to the voluntary "responsibility deal" between industry and government. But Prof John Ashton, president of the Faculty of Public Health, said the approach "lacked credibility". The Department of Health (DoH) said it would "make a huge...

Light shed on how genes shape face

Scientists are starting to understand why one person's face can look so different from another's. Working on mice, researchers have identified thousands of small regions of DNA that influence the way facial features develop. The study also shows that tweaks to genetic material can subtly alter face shape. The findings, published in Science, could also help researchers to learn how facial birth defects arise. The researchers said that although the work was carried out on animals,...

Slow metabolism 'obesity excuse' true

The mocked "obesity excuse" of being born with a slow metabolism is actually true for some people, say researchers. A team at the University of Cambridge has found the first proof that mutated DNA does indeed slow metabolism. The researchers say fewer than one in 100 people are affected and are often severely obese by early childhood. The findings, published in the journal Cell, may lead to new obesity treatments even for people without the mutation. Scientists at the...
