Brain Cancer Radiation Therapy

Brain cancer radiation therapy is the process in which a particular form of energy is used to destroy cancerous cells in the body. This treatment is also used to reduce the size of the tumors that are present within the body. This is made possible by the fact that the genetic information on the abnormal cells is eliminated.

Once this occurs, the cells are no longer able to go through their traditional characteristics of dividing and spreading through the body. The ultimate goal associated with this type of brain cancer treatment is to successfully eliminate the largest number of abnormal cells as possible while not damaging the cells that surround the abnormal ones that are considered to be healthy. Here, you will learn more information pertaining to brain cancer radiation therapy.

External Therapy

Individuals that require brain cancer radiation therapy may opt for the external therapy treatment. This type of radiation therapy is made possible by a machine in the external environment of the patient. The technologically advanced machine will emit a large amount of radiation towards the area that the cancer is present.

Those that choose this type of treatment may have it performed on an outpatient basis. While used in other types of cancer such as those that affect the bladder, the prostate and similar areas, this form of treatment has proven to be highly successful for those suffering from the uncomfortable symptoms associated with brain tumors. There are two subtypes of radiation treatment that is considered to be external. They are "Intraoperative Radiation Therapy" and "Prophylactic Cranial Irradiation".

Internal Therapy

Internal therapy is another type of brain cancer radiation therapy that many doctors and patients agree is highly beneficial in killing cancerous cells and reducing the sizes of tumors within the body. Instead of using a machine that emits radiation, the radiation is typically contained within a container that is often identified as an implant.

Individuals that engage in this type of treatment are typically admitted to the hospital. This is because of the fact that the implant must be placed within the body so that the medication may start to work against the cancerous cells. Internal therapy is identified by the way that the medication implant is placed in the body. There are two subtypes. The first is called "Interstitial Radiation". The second type of internal based radiation is identified as "Intracavitary Radiation".

Conclusion

Brain cancer radiation therapy has been successful in nine of ten cases. While there are some side effects and symptoms that may be potentially dangerous, this is rare as medical doctors watch the individual undergoing therapy very closely. This means that if any complications come up, they may be dealt with quickly. If you have brain cancer, it is important to ensure that you discuss all of your treatment options with a doctor prior to initiating brain cancer radiation therapy.

The Brain Cancer Risk From Careless Radiation Testing at Hospitals

It started when my brother-in-law, who is kind of fond of the drink, fell down heavily at home one day when a stroke hit him. It was a minor stroke that he recovered from with a week in hospital; but to be on the safe side, the doctors recommended a kind of radiation test that they said would help them identify the exact spot the blockage existed in that had caused the blood flow problem in his brain. The radiation test was to be a procedure called the CT brain perfusion scan; it was kind of scary to hear about - it was to beam the equivalent of hundreds of x-rays worth of radiation into his brain. We might have suspected that this would cause problems later on, but all the high-tech wizardry we were surrounded by kind of helped calm our fears. And then it started - there was the perfect circle of hair that just dropped out of his head one day soon.

When we brought it up with the doctor, he didn't say that he believed that there was something wrong with the procedure; he wondered if my brother-in-law had started combing his hair in the wrong direction. This was kind of like the way Toyota likes to blame the out-of-control acceleration in their cars on drivers getting their pedals mixed up. We began to read up, and then came this breaking story in the New York Times that really was a wake-up call. That CT brain scan was what was behind it all the time. Those machines (made by GE, Toshiba and others) didn't have the software set up so that they would be easy for the technicians to use; the companies didn't train the lab technicians properly, and my brother-in-law had ended up getting 10 times the radiation he should have. And there are so many people this is happening to that there's actually a class action lawsuit being planned.

What exactly happens then when this machine zaps your brain? The most visible thing that happens right away is that you lose your hair for a few weeks. But there are more serious things that go on within. Brain cancer and memory loss happen to be real possibilities. The problem here is that there is so much going on on the cutting-edge science of radiation therapy that there has been not enough time to discover everything that can go wrong, and to establish training procedures that will help lab technicians learn their skills properly before they zap anyone into orbit. There actually is no legal limit to how much radiation they can give you either.

While they suspect that brain cancer could be a strong possibility, there hasn't been enough time that has elapsed that they could actually find out how serious things can be. Perhaps the problem is that we've come to depend on safety features built into everything we use. If you don't close the door of your microwave properly, it's not going to work; if you don't close the door of your car properly, it's going to warn you repeatedly. Technicians who work these machines easily use the automated features provided, assuming that they've been designed to be idiot proof - to warn them when they are about to zap someone into getting brain cancer. They forget that idiot-proofing is just a consumer innovation. Professional equipment doesn't come with these features, because they assume that technicians know what they are doing. If it's at all comforting to hear this, a few high-ranking hospital staff at hospitals around the country have suffered the same effects. It just goes to show how light the veneer of the safety is that we take for granted.

Protect Your Skull from Cell Phone Radiation - Play it Safe

When I was a young man in my 20s, I was running a business and I was quite proud of myself because we were doing fairly well, and for young man I was quite pleased with the monetary results each month. Indeed, I had one of the first cell phones, and I was paying between $.60 and a dollar per minute, and yet it seemed to pay for itself because of the inherent efficiency of rapid communication.

None of my competitors had a mobile phone yet, the best they had were those repeater phones were you had to push to talk, and they were much cheaper either. Needless to say, I was running over 1,000 hours per month on average.

Unfortunately, they didn't know back then all the know today about how dangerous cell phones could be to the biosystem. It turns out those phones back then operated on 3 Watts of power, no, that's not very much. But since the frequency of the cellular phones back then were in the microwave range, which they are today, that meant that I was holding the phone up to my ear, and that wasn't very good for the issues with cell phone radiation. Now then, my first phone sat underneath the seat of my vehicle, and it probably cooked the underside of my seat.

Later, I had a transportable phone which I walked around with, but again it was away from my body, so it was a little bit safer. Eventually I had a handheld phone when they finally got invented, which had quite a bit more power, but I held that unit up to my ear. Later on, about eight-years later, the cell phones started using less power and they went to a different system. The wattage was significantly less, as it is today, and therefore it's probably not too much of a problem as people hold this up to their ears, provided they are not using the phone a significant percentage of the time, let's say 500 plus minutes per month, but to be totally precise, you'd need to look at the data yourself.

However, people also commonly wore their cell phone on their belt. Those microwave frequencies can damage DNA, and the last place you'd want to put it is near your reproductive system, in fact you would not want it anywhere near. Nor would you want it next your brain, even though your skull could somewhat protect you. Remember microwave frequencies go through things; that's why your microwave oven has special shielding.

There was an interesting article recently in Kurzweil's Accelerating Intelligence Online News titled; "New Studies Reveal Evidence that Cell Phone Radiation Damages DNA, Brain, and Sperm" by the Editor posted on May 24, 2011. The article stated that a:

"New independent studies offer proof that confirms findings from the Council of Europe: pulsed digital signals from cell phones disrupt DNA, impair brain function, and lower sperm count, according to a statement by the EHT. It was found that four hours of exposure to RF-EMF disrupts the ability of human brain cells to repair damaged genes. Other new work from Australia shows damage to human sperm."

Brain cancer is quite serious, and so are things like Alzheimer, and other diseases of the brain. Your brain is your most important organ, and therefore you should be thinking, and playing it safe. Indeed I hope you will please consider all this and think on it.
