This is examined under Reseach - Epidemiology - Cell Phone Studies. All of the studies except that of Hardell and colleagues showed no association between wireless phones and brain cancer. Hardell's 2000 study showed a slightly increased risk of tumours on the same side as the phone was used, but this was based on small numbers and was not supported in the studies by Inskip and Muscat. His 2002 study, which led to 2 papers in 2002 and 2 more in 2003, showed similar findings.

I strongly considered leaving this question off the list, since I can't honestly give you a straight answer. Much research has been done to investigate possible links between RF and cancer, but no studies have yet found one. Many people choose to ignore these studies, because most of them are funded by cell phone companies.

In recent years, publicity, speculation, and concern over claims of possible health effects due to RF emissions from hand-held wireless telephones prompted industry-sponsored groups to initiate research programs to investigate whether there is any risk to users of these devices.

There is no convincing scientific evidence that the use of mobile phones can cause brain tumours or other cancers in humans. It is the consensus of the world wide scientific community that the low powered radio signals produced by a mobile phone do not have sufficient intrinsic energy to affect genetic material.

Single brief seizures do not cause brain damage. Although tonic-clonic (grand mal) seizures, lasting longer than 20 minutes may injure the brain, there is no evidence that shorter seizures, lasting less than 20 minutes, cause permanent injury to the brain.

Most reviews have concluded that there is no evidence that wireless phones have any adverse effects. However, they also conclude that RF radiation in the wireless phone range may produce biological effects, and that more research is needed. It is important to note the difference between biological effects and adverse effects due to exposure to electromagnetic fields. Biological effects are detectable changes that occur in an organism, tissue or cell.

Some research suggests that RF radiation in the cell phone range may have subtle effects on brain wave patterns as seen on electroencephalograms (EEGs), on sleep, and cognitive function. The results, however, have not been consistent. There is no evidence that RF radiation in the cell phone range causes adverse effects on brain function in humans. As a result, the effects of cell phones on brain function continue to be an area that requires further research.

NO. More than 2000 clinical studies have been conducted on the use of LILT and in all of these studies no mutational effects have ever been observed resulting from therapy with wavelengths in the red or near-infrared ranges in the doses used by laser therapy.

The answer is no. No mutational effects have been observed resulting from light with wavelengths in the red or infra-red range and of doses used within LLLT. But what happens if I treat someone who has cancer and is unaware of it? Can the cancer's growth be stimulated? The effects of LLLT on cancer cells in vitro have been studied, and it was observed that they can be stimulated by laser light. However, with respect to a cancer in vivo, the situation is rather different.

Severe, long-standing GERD can damage the esophagus and cause a condition known as Barrett's esophagus wherein the normal lining of the esophagus is replaced by a lining more like that of the stomach or intestine. It is thought that this replacement may be an attempt by the body to protect itself from further injury by acid. The risk of esophageal cancer appears to increase significantly in patients with Barrett's esophagus. The only way to diagnose Barrett's esophagus is by endoscopy.

There are no known causes of prostate cancer. Approximately 10 % of prostate cancers are inherited but the remaining cases occur at random. A “prostate cancer gene” has not yet been identified. There are links between diets rich in saturated fats and an increased incidence of prostate cancer but this evidence is based on epidemiologic data and not based on data obtained from clinical practices.

Gallstones are the most common risk factor for gallbladder cancer. Between 75% and 90% of people with gallbladder cancer also have gallstones and an inflamed gallbladder. Gallbladder cancer is more likely to happen if your gallbladder has a single large gallstone than several small ones. Doctors believe that large gallstones grow over a long time, irritating the gallbladder wall and increasing the risk for gallbladder cancer.

Laser beam is very safe because laser medicine generally utilizes wavelengths above 632 nm (nanometer). Therefore the laser beam is not ionizing radiation (which can cause cancer) like X-rays, Gamma rays etc. Sunlight contains cancer causing wavelengths (below 320 nm), which is ultraviolet. There is no certain limit for penetration of laser light. It spreads in all directions and is absorbed in tissues. Light's intensity weakens the deeper from the target point it goes.

In general, seizures do not cause permanent brain damage. The brain has an amazing amount of unused capacity and even if cells are damaged during a seizure, your dog should have the ability to relearn. If your dog has had a cluster of severe seizures you may notice some changes in their behavior, but these should be temporary. Most dogs fully recover from seizures in a few days but for some it may take a few weeks.

Some brain tumors are cancerous and some are not. Malignant tumors are considered cancer. Two of the most common forms of brain cancer are metastatic brain tumors (brain metastases) and glioblastoma multiforme (GBM). Brain cancer cells mutate and lose their normal form or structure. This is called anaplasia. The degree of anaplasia helps to forecast a tumor's growth potential. The most rapidly growing tumors have the highest degree of anaplasia. Benign tumors are not considered cancer.

The list of alleged health outcomes associated with the use of wireless phones includes headaches, memory loss, fatigue, and other subjective symptoms. None of these has been proven to be due to the electromagnetic field (EMF) generated by the phone. Controlled experiments have not been able to show an increased incidence of these symptoms in those exposed to the EMF from a phone, compared to those sham-exposed.

One study has been completed in Sweden and Norway to determine whether users of digital phones experience greater subjective health symptoms (headaches, dizziness, fatigue, etc.) than those using analog phones. The fundamental question raised by this study was unsupported by the data. In fact, there is nothing in the study that suggests wireless users have a greater incidence of headaches than the general population.

Yes not only does it cause damage to the brain it can also cause possible damage to the kidneys and immune system. Ref: Press conference of the Swedish Council for Planning and Coordinating Research Stockholm 19 February 1998 "Amalgam can cause brain damage in Children."

The available evidence speaks strongly against this possibility. Patients receiving ECT show no elevation of brain enzymes and proteins that are released into the bloodstream when brain damage occurs, such as after a stroke. Carefully-controlled animal studies have shown no evidence of brain damage from brief seizures as given with ECT, and sensitive brain-imaging studies performed months after ECT have shown no structural changes.
