    (NaturalNews) The results of the decade-long Interphone study on cell phone safety are that heavy cell phone use increases the risk of developing brain tumors later in life. The study, which focused on three types of brain cancer and tumors of the parotid gland, found a significant increase in cancer after a decade or more of cell phone use. When a cell phone tower connects with a cell phone, electromagnetic radiation is created. When the cell phone is held against the ear, this radiation penetrates the brain, particularly in children. According to the Daily Telegraph in London, the World Health...

    Cancer often strikes its final, fatal blow when a tumor spreads to other organs. A new study published online today in Science sheds light on this poorly understood process, called metastasis. The researchers report that mutations in mitochondrial DNA can spur metastasis and that it can be reversed with drugs, at least in mice. Mitochondria are the tiny organelles inherited from your mom that serve as the cell's powerhouses. They have their own DNA, called mtDNA. Ten years ago, cancer researchers noticed that mtDNA in tumor cells tends to be riddled with mutations--far more than in normal tissues. (This is...

    Within the next few months, researchers at three medical centers expect to start the first test in patients of one of the most promising — and contentious — ideas about the cause and treatment of cancer. The idea is to take aim at what some scientists say are cancerous stem cells — aberrant cells that maintain and propagate malignant tumors. Although many scientists have assumed that cancer cells are immortal — that they divide and grow indefinitely — most can only divide a certain number of times before dying. The stem-cell hypothesis says that cancers themselves may not die because...

    When the U.S. Food and Drug Administration approved implanting microchips in humans, the manufacturer said it would save lives, letting doctors scan the tiny transponders to access patients' medical records almost instantly. The FDA found "reasonable assurance" the device was safe, and a sub-agency even called it one of 2005's top "innovative technologies." But neither the company nor the regulators publicly mentioned this: A series of veterinary and toxicology studies, dating to the mid-1990s, stated that chip implants had "induced" malignant tumors in some lab mice and rats. "The transponders were the cause of the tumors," said Keith Johnson, a...

Cancer Agency in Vancouver. The team, led by Dr. Poul Sorensen, says the gene has the power to suppress the growth of human tumours in multiple cancers, including breast, lung and liver. The gene, HACE 1, helps cells fight off stress that, left unchecked, opens the door to formation of multiple tumours. Dr. Sorensen's team found cancerous cells form tumours...

    Canberra, Australia (LifeNews.com) -- An MIT professor says that embryonic stem cell research is nowhere close to helping patients. He said that's because scientists haven't yet figured out how to stop embryonic stem cells from causing tumors when injected into patients. Professor James Sherley, a stem cell researcher at the Massachusetts Institute of Technology, was in Australia to talk with lawmakers about why they should resist backing legislation promoting human cloning. Sherley said that embryonic stem cells cause tumors and cancers when injected into human tissue and, as a result, they can't be used to treat patients with various diseases....

But a potentially cancerous side effect might put the brakes on such therapies for humans. Parkinson's disease kills off neurons that produce the neurotransmitter dopamine, leading to problems with movement and balance. Most treatments currently involve replenishing the dopamine through drugs. But researchers...

    EMBRYONIC stem cells turn into tumours when injected into human tissue and therefore cannot be used to treat diseases, a visiting US expert said today. Professor James Sherley, a researcher in the field of adult stem cells, is one of a series of experts in Canberra to lobby MPs ahead of a conscience vote on whether a ban on therapeutic cloning should be overturned. Prof Sherley, from Boston's Massachusetts Institute of Technology (MIT), today said scientists had failed to reveal problems with embryonic stem cells that would prevent them being used in humans. The unique feature of embryonic stem cells...

    Doctors had diagnosed an ear infection in Robyn Miller's 5-week-old daughter Megan, but Ms. Miller had only to gaze into Megan's blank face to know that something more was going on. "Her eyes dipped down so low that most of what you could see was white," she recalled. M.R.I. scans revealed a teratoma in Megan's skull — a noncancerous mass of rapidly dividing cells, the result of natural developmental processes gone awry. "I always thought a benign tumor meant you were going to be O.K.," said Ms. Miller, who lives in Melbourne, Australia. "But this tumor was the size of...
  • Study Says Stem Cell 'Fusion' Occurs In Tumors

    An Oregon Health & Science University study is adding credence to an increasingly popular theory that fusion is what bonds stem cells with bone marrow cells to regenerate organ tissue. Scientists in the OHSU School of Medicine found that transplanted cells derived from adult bone marrow can fuse with intestinal stem cells of both normal and diseased tissue comprising the cellular lining of intestinal walls, known as the epithelium. The findings, reported recently in the Proceedings of the National Academy of Sciences, point to the integral role of bone marrow-derived cells in not only regeneration of damaged tissue, but also...

Ben Harder The Dominican Republic is known among tourists for its white sands, magnificent waterfalls, and unusual wildlife. But none of those was the attraction that drew Charles A. Reinwald. He came for a rendezvous with an ultrasound device. Reinwald had aggressive prostate cancer, and he didn't care for the treatment options available in the United States. So, one day in late June 2004, Reinwald traveled from his home in Tequesta, Fla., to a hospital in the Dominican city of Santiago. There,...

    A freshly published study (PDF) in the British Medical Journal, jointly conducted by four English universities and sponsored by the World Health Organization's International Agency for Research on Cancer (IARC), has found no causal relationship between cell phone usage and glioma, the most common and deadliest of the different types of brain tumors. Nearly 2,000 confirmed glioma sufferers were selected from hospital oncology departments and cancer registries, though 30 percent of the patients died before completing the interview process. After discounting other nonrespondents, 51 percent of the original population, or 966 cases, were included in the study. The demographic makeup...

    Traditional attempts to destroy cancerous tumors involve treatments such as chemotherapy that kill healthy cells right along with mutated ones, often leaving patients weak, nauseous, hairless and vulnerable to infection. But now biologists and engineers at the Massachusetts Institute of Technology have engineered a dual-chamber molecular bomb designed to infiltrate a tumor, shut down its blood vessels — thereby sealing off the exits — and detonate a dose of cancer-killing toxins. The drug-delivering nanocell, reported recently in the journal Nature, could help usher in more effective cancer therapies that pinpoint and obliterate disease without harming normal, healthy cells. "By having...

    PITTSBURGH, August 8, 2005 (LifeSiteNews.com) - Researchers at the University of Pittsburgh have revealed findings that some placental cells have many of the same characteristics of embryonic stem cells. Like umbilical cords, the placenta is routinely discarded after a baby is born, and is a rich source of these cells. The cells are readily available and have been shown not to produce the tumors that are a major medical barrier to using embryo cells in direct treatments. "We think it would be easier to get these to the clinic than [embryonic stem] cells," said Stephen Strom, an associate professor of...

    PHILADELPHIA – Nano-sized particles embedded with bright, light-emitting molecules have enabled researchers to visualize a tumor more than one centimeter below the skin surface using only infrared light. A team of chemists, bioengineers and medical researchers based at the University of Pennsylvania and the University of Minnesota has lodged fluorescent materials called porphyrins within the surface of a polymersome, a cell-like vesicle, to image a tumor within a living rodent. Their findings, which represent a proof of principle for the use of emissive polymersomes to target and visualize tumors, appear in the Feb. 7 online early edition of the Proceedings...

    Cancerous and benign growths can be removed through the use of a non-invasive, experimental device that uses focused ultrasound to break up the tumors. The system, ExAblate 2000, developed by the Israeli InSightec company, is tracked in real-time using an MRI scanner. The treatment is being clinically tested for use in fighting breast cancer, brain tumors and uterine fibroids, and it may preclude the need for many hysterectomies regularly performed today. While experimental trials are underway in medical centers around the world, in Israel, the treatment is already being implemented regularly at Haddasah and Sheba hospitals. And it will shortly...
