One person in five will develop cancer, according to WHO estimates, and the disease will touch 92% of people, either through their own diagnosis or that of a close family member. Continue reading...

Polio virus detected in London days before ministers cut global eradication funding
Campaigner criticises ‘shortsighted and self-defeating’ decision and says it increases risk to the UK public The polio virus was detected in London sewage for the second time this year, days before ministers withdrew funding for global polio eradication efforts. Its detection reveals the spending cuts to be “shortsighted and self-defeating”, campaigners said. Polio is an extremely infectious viral disease, which typically affects young children under-five. It can cause paralysis by damaging nerves in the spine and base of the brain, and can be life-threatening if it affects muscles used for breathing. Continue reading...
