I recently heard from a man who was advised to have a CT scan of his brain, which he underwent. The reason was that he has a hand tremor. His age is 63. He got a second opinion before submitting to the brain scan. Both doctors strongly urged him to do it because they thought it was highly possible he could have a brain tumor. And ultimately, he did it because he was freaked out about that. Who wants to live with uncertainty about whether or not you have a brain tumor? So, he did  it, and fortunately, the scan came back negative. But, how likely was it that he had a brain tumor? The most common symptoms of a brain tumor are headaches, seizures, visual problems, hearing problems, garbled speech, gait problems, cognitive and personality disruptions, and nausea/vomiting. This man had none of those symptoms. The chance that a brain tumor would present with one-sided hand tremor and nothing else is exceedingly small. Laughably small. However, to treat peripheral neuropathy, he has been taking two anti-seizure drugs, Neurontin and Tegretol, for decades, and both of those drugs are known to cause tremors with longterm use. Weren't those drugs the most likely cause of his hand tremor and not a brain tumor? He received a whopping dose of radiation from that CT scan, and the dye they injected into him is hardly safe either. I think it was medical malpractice for them to order that scan. There was no justification for it. And in the tiny, remote possibility that he had a brain tumor, other symptoms would have manifested soon enough to point to it. There was no need to go fishing for it. This is prime example of medical exploitation, and it happens countless times every day. And we are all victims because the costs get passed down to all of us through higher medical insurance premiums and the taxes that we pay. And of course, it is only going to get worse under Obama Care. Now, more than ever, you need to be wary and remain independent when it comes to all medical decisions. It's a jungle out there, and the system is rigged against patients. Don't be overly impressed with any  doctor. Be prepared to make your own decisions concerning your health.
