You Don't Have to be Afraid of Cancer Anymore Bill Sardi See book keywords and concepts

X-ray radiation from medical imaging and CT scans are also believed to increase the risk for cancer. A report issued by the Food & Drug Administration now suggests the risk for cancer from medical x-rays may be as much as 1 in 1,000. There are over 3 billion x-ray images taken annually in the world. Dr. Richard C. Semelka, MD, says patients receiving multiple CT scans today are being exposed to doses of radiation comparable to those given off by the x-ray machines used in the 1930s and 1940s. Cancers do not emanate from x-rays till years later.

Source: medical imaging Newsletter One out of three mammograms produce abnormal results that require further testing, but subsequent tests reveal no cancer. About 19% of biopsies are needless and cause 16 million false alarms over 10 years. [New England Journal Medicine, April 16, 1998] If a group of women begin breast screening at age 40, by age 50 half of them will have at least one false positive test and undergo needless biopsy. [The Ottawa Citizen, Sept. 4, 2002] Out of 100 positive mammograms, only 20 will actually indicate the presence of cancer. [LA Times Aug.

Overtreated: Why Too Much Medicine Is Making Us Sicker and Poorer Shannon Brownlee See book keywords and concepts

Just like high-tech infrared photography, medical imaging can trick physicians into thinking they know more than they really do. Doctors routinely dismiss possible diagnoses because their high-tech tools show a negative result. False-positive results—a scan that indicates there's something wrong when there isn't—can lead them to perform even more unnecessary tests, some of which can be invasive and potentially dangerous, in an effort to confirm the (incorrect) diagnosis. The power of imaging tests to fool doctors can be seen readily in appendicitis.

Health care economics: Diseases are too profitable to prevent or cure Mike Adams, the Health Ranger See article keywords and concepts

Because everybody's making money from disease, including the doctors, hospitals, medical imaging specialists, oncologists, radiologists, anesthesiologists and, of course, psychiatrists, who are now making money by imagining that people have all sorts of brain chemistry disorders like Road Rage Disorder that they claim need to be treated with prescription drugs.

The tale of doctors who tried to create art Mike Adams, the Health Ranger See article keywords and concepts

Using medical imaging equipment and an elaborate system of fiber classification, they were able to catalog and name over two hundred types of microscopic fibers found in the canvas. With this knowledge, the doctors were certain they now understood art. They knew the fiber structure of the canvas and the chemical composition of the inks. What more could art be made of? Armed with this new scientific knowledge of art, they gathered enormous samples of all the fibers, chemicals and inks now known and combined them in a giant mass of ink colors and canvas fibers. Only it still wasn't art.

Understanding Medicinal Plants: Their Chemistry And Therapeutic Action Bryan Hanson, PhD See book keywords and concepts

This is a medical imaging technique that uses the same principle as NMR. The word nuclear was removed from the name because of the negative connotations of the term.1-'' Let's go straight to how we can use C-13 NMR data to help find the structure of a molecule. A C-13 NMR spectrum of the same sample we used for our IR example (from Figure 5.11) is shown in Figure 5.13. The horizontal axis is called the chemical shift and is measured in parts per million (ppm). The vertical axis corresponds to peak strength; peaks point up in NMR spectroscopy.

The Secret History of the War on Cancer Devra Davis See book keywords and concepts

A single computerized scan of the stomach today can give half the dose that was shown to induce cancer in those who survived the atomic bomb blasts in Japan. The ACR advises that "the current annual collective dose estimate from medical exposure in the United States has been calculated as roughly equivalent to the total worldwide collective dose generated by the nuclear catastrophe at Chernobyl."20 Let me translate this.

Living Downstream Sandra Steingraber See book keywords and concepts

Medical imaging technology introduced in the 1980s profoundly altered the ways in which brain cancers are diagnosed. However, the greatest rise in brain cancer occurred well before this time and has continued to increase, even though use of the new methodologies has leveled off. Moreover, brain cancer incidence is also rising in countries where enthusiasm or budgets for these new imaging technologies are much less. These kinds of international comparisons are made possible because of a little-known office of the World Health Organization.

Common electropollution components include computers, underground radio transmitter grids, medical imaging, and high-voltage power lines. Home devices that may affect us include hair dryers and electric blankets. Some common avenues of electrical exposure are seen in the following chart.

It was not until the 1970s that it became adapted to medical imaging systems. To visualize living tissue, MRI capitalizes on the magnetic properties of protons (hydrogen atoms in water). Protons appear to behave like tiny spinning, magnetic earths. Protons have axes forming north and south magnetic poles. In the strong magnetic field of MRI, the random distribution of "N" and "S" poles becomes changed. All the protons align their axes in the direction of orientation of the magnetic field. A second stimulus, a radio frequency beam, is then applied.
