RE: Another study show cell-phone tumor link
I just read an article on the FDA review of this research. Unless the FDA is wrong about their methodology, the research can be dismissed as worthless. They got their data from responses to a mailed survey. Self selection is an obvious problem here. http://tinyurl.com/nf7o7 quote The Food and Drug Administration said that finding was inconsistent with the conclusions reached by other studies and pointed out several shortcomings, including the design of the study, which was conducted by surveys distributed by mail, and the lack of supporting data from laboratory animals. That makes the conclusion difficult to interpret, the FDA said on its Web site. end quote Dan M. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of The Fool Sent: Sunday, April 02, 2006 9:05 PM To: Killer Bs Discussion Subject: Re: Another study show cell-phone tumor link From: [EMAIL PROTECTED] In a message dated 3/31/2006 6:28:23 PM Eastern Daylight Time, [EMAIL PROTECTED] writes: A total 85 of these 905 cases were so-called high users of mobile phones, that is they began early to use mobile and, or wireless telephones and used them a lot, the study said.

Re: Another study show cell-phone tumor link
From Futurelab's Blog at MIT, a story about how brain damage -- whether *from* cell phone use or *causing* excessive self-important cell phone use -- might eventually be repaired: Researchers at the University of Padua in Italy have developed neuro-chips in which living brain cells and silicon circuits are coupled together. The scientists squeezed more than 16,000 electronic transistors and hundreds of capacitors onto a silicon chip just 1 millimeter square in size. They used proteins found in the brain to glue neurons onto the chip. The proteins acted as more than just a simple adhesive. The proteins allowed the neuro-chip's electronic components and its living cells to communicate with each other. Electrical signals from neurons were recorded using the chip's transistors, while the chip's capacitors were used to stimulate the neurons. http://blog.futurelab.net/2006/03/brain_cells_fused_with_compute.html Dave ___ http://www.mccmedia.com/mailman/listinfo/brin-l
Re: Another study show cell-phone tumor link
Acoustic neuromas are slow-growing noncancerous tumors that develop on a nerve linking the brain and the inner ear. Technically these tumors are more accurately called vestibular schwannomas (They arise from the vestibular branch (balance controlling) rather than the cochlear (hearing contolling - thus acoustic) branch of the 8th cranial nerve and the cells are scwhann cells not neural cells). They are benign neoplasms (not sure where the popularly stated notion that benign tumors are not cancers comes from but this is not really a good distinction since the border between benign and malignant tumors of many types is not sharp). We looked at DNA damage in animals, not in humans, and found that cell phone radiation can damage DNA, he said. The body's immune system has the ability to repair DNA breaks, but sometimes it can make a mistake and cause a mutation, which could be the first step toward cancer, Lai said. In instances like this dose is all important. How much radiation over how long a period of time? What size are the animals? (Radiation may penetrate to the vestibular nerves more easily in a small animal than a human). The fact of the matter is that I have been doing neuroradiology for about 30 years and I have seen no rise in the incidence of vestibular scwhannomas in my practice and none of my colleagues has commented to me that they have seen any increased incidence. I will hold an informal poll at the next national neuroradiology meeting in May and get back to you all but for the moment I remain very skeptical ___ http://www.mccmedia.com/mailman/listinfo/brin-l ___ http://www.mccmedia.com/mailman/listinfo/brin-l
Re: Another study show cell-phone tumor link
Q. for Dr. Z: Is an acoustic neuroma considered a type of brain tumor? (Based on what I have read on the subject, ISTM the answer is No, but then IANAMD, nor do I play one on TV . . . ) It is not a tumor of the brain but rather a tumor arising from cells (schwann cells) that cover nerves leaving the brain. Most but not all are benign. Generically we lump all of these together and central nervous system tumors but they do not arise from the cells that typically cause tumors in the brain itself. Brain tumor most often arise from support cells in the brain (astrocytes, oligodendrocytes, ependymocytes) and lest commonly from neurons (Ganglioglioma, Central Neurocytoma, Primitive neuroectodermal tumors). Nerves cells rarely divide after developement and therefore are not subject to harmful mutations. ___ http://www.mccmedia.com/mailman/listinfo/brin-l

From my experience, I recommend a nice Mixed Oligo-Astrocytoma of the frontal lobe over, for example, Anaplastic Ependymoma. The former, in my experience, is a happy little indolent tumor that is easily removed and treated with just about the gentlest chemotherapy that can be had.

By far the best brain tumor to have is Juvenile Pilocytic Astrocytoma of the cerebellum. Totally benign completely resectable. If you are going to have an oligo it is betterf to be a pure oligo but the right anterior ftontal lobe is a good place because a wide resection is possible. On balance however the best is no tumor at all. ___ http://www.mccmedia.com/mailman/listinfo/brin-l
