Incredible images of DNA in action have been captured by scientists who will use them to design cancer drugs. Researcher Dr Alessandro Vannini said the pictures were beautiful and in artistic comparisons were definitely a Van Gogh, since they capture a fundamental part of all plant and animal life, called RNA polymerase III, reading the genetic instructions contained in DNA. It is a process that gets hijacked by cancer.
Researchers at an Oxford hospital have developed artificial intelligence (AI) that can diagnose scans for heart disease and lung cancer. The systems will save billions of pounds by enabling the diseases to be picked up much earlier. The heart disease technology will start to be available to NHS hospitals for free this summer.
Earlier this year, researchers sparked a debate by suggesting that random cell mutations, rather than lifestyle choices, played a significant role in the development of tumors, a finding dubbed the “bad luck hypothesis.” A new study has nevertheless led scientists to believe that external influences have a far greater impact, implying that many cancers may be more preventable than previously thought.
Most types of cancer can be put down to bad luck rather than risk factors such as smoking, a study has suggested. US teams were trying to explain why some tissues were millions of times more vulnerable to cancer than others.
In what is being viewed as one of the most important discoveries in the battle against cancer, a major review of trials and studies has revealed that long-term use of low-dose aspirin reduces the risk of developing major cancers and dying from them by around one-third.
The WHO’s International Agency for Research on Cancer (IARC) said cancer was growing “at an alarming pace” worldwide and new strategies were needed to curb the sometimes fatal and often costly disease.
Cardiovascular diseases remain the number one cause of death throughout the world, and killed nearly 17 million people in 2011, that is 3 in every 10 deaths. Of these, 7 million people died of ischemic heart disease and 6.2 million from stroke, reports the World Health Organization.
Latin America's growing prosperity is fuelling a cancer epidemic that threatens to overwhelm the region unless governments take urgent preventive action, a study warned.
Bolivian president, Evo Morales, says his Venezuelan counterpart, Hugo Rafael Chávez Frías, is in stable conditions but still suffering from relapses in his recovery from a fourth round of surgery for cancer. Morales couldn't meet with Chavez but said doctors and relatives of Chávez informed him about his current condition.
Venezuelan doctor Jose Rafael Marquina, who is based in the US and is known for his accurate prognoses on President Hugo Chavez’s health, told a local Florida radio that the Venezuelan leader Chavez has “between two and three months to live”.
