ATLANTA — Cancer is over one hundred different diseases hiding under one name. That's why, just as there isn't one universal way to treat cancer, there also isn't one universal way to detect it. But that doesn't mean scientists aren't trying: If researchers can find a unique signature or "biomarker" of cancer — meaning a characteristic that all cancerous cells share but healthy cells do not — they may be able to create a simple test to detect it. One unique cancer biomarker could be DNA. Of course, DNA isn't something that's unique to cancer cells — every cell in the body has it. But according to a team of researchers from Australia, cancer DNA takes on a different structure than healthy DNA, and that's something scientists could target. [7 Diseases You Can Learn About from a Genetic Test] That was the premise of a paper that the team published last December in Nature Communications. They found that because of its unique shape, DNA from cancer cells bound … [Read more...] about Will There Ever Be a Universal Test to Detect Cancer?
Potential cancer cure
Hilary Brueck, provided by Published 8:11 am PST, Friday, February 22, 2019 Dan Kitwood / Getty Images There is no cure for cancer, but there are many ways we can reduce our risk of developing some types of the deadly class of diseases. Some of the most powerful ways to reduce your cancer risk include staying active, not smoking, and maintaining a healthy weight, especially around your waistline. Vitamin-rich plants and fiberous foods also play an important role. Cancer is a dangerous and common class of diseases: it's the second-leading cause of death in the US, and you probably know at least a few people who have been diagnosed. More than 15.5 million Americans — nearly one in 20 — have had cancer in the past or currently do, according to the American Cancer Society. Yet nearly half of US cancer cases and deaths are linked to preventable risk factors. Similarly, experts in the UK estimate that 4 in 10 cancer cases there are preventable with … [Read more...] about 32 science-backed ways to reduce your risk of developing cancer
Is there any more tantalizing headline than “Scientists discover a cure for cancer”? Some version of this fantastical claim has been dropped into the news cycle with the regularity of a super blood wolf moon for the better part of a century. In 1998, James Watson told the New York Times a cancer cure would arrive by Y2K. This magazine hasn’t been immune either, running an “End of Cancer” headline a few years later. Each instance stirs up hope for patients and their families desperate to find a solution, no matter the risk or cost. And yet, here we are in 2019, with that constellation of complex, diverse diseases we lump together and call “cancer” for convenience's sake still killing one in eight men and one in 11 women, according to the World Health Organization’s latest stats. You’d think creators and consumers of news would have learned their lesson by now. But the latest version of the fake cancer cure story is even more … [Read more...] about The ‘Complete’ Cancer Cure Story Is Both Bogus and Tragic

A new study has found that dirt — yes, actual dirt — could be a possible cure for what is considered the "modern-day health epidemic."A study conducted by the University of South Australia (UniSA) that investigated the effect of clay materials on drug delivery was the source of this unexpected discovery. Tahnee Dening, a UniSA and Ph.D. candidate, learned that clay materials have the surprising ability to reduce fat droplets in the gut by soaking them up.Dening had been investigating how clay materials could improve the oral delivery and absorption of antipsychotic drugs, but during this study, she noticed that the clay particles were behaving in an unexpected manner.The dirt … [Read more...] about Clay Could Cure Obesity By Trapping Fat, Study Reveals
Restricting the ability of cancer cells to metabolize sugar could make oncolytic viruses more effective at attacking them, suggests a study published in the journal Cancer Research. Viruses that are trained to attack cancer cells - known as oncolytic viruses - can kill tumors without affecting healthy cells nearby. They normally work by invading the cells, multiplying, and destroying the tumor from inside. They are currently being tested in clinical trials. In this new study, a team of scientists exposed lung, ovarian and colon cancer cells, and mouse models, to conditions similar to those in the human body, and investigated how manipulating cell metabolism can make cancer more vulnerable to oncolytic viruses. In the lab, scientists usually keep cells at the perfect temperature and provide them with lots of glucose, as it's easier to grow and store them this way. In this study, the researchers changed the lab conditions to make them reflect what actually happens in the human body, … [Read more...] about Altering Cancer Metabolism Helps Treatments Attack Tumors
