Nanotechnology Tackles Brain Cancer



Brain cancer can be counted among the most deadly and intractable diseases. Often diagnosed after a patient exhibits symptoms such as nausea, dizziness, uncharacteristic behavior changes, or paralysis, the growing mass of a brain tumor will continue to squeeze out normal tissue and degrade the brain’s function if left untreated. But treatment is elusive. Tumors may be embedded in regions of the brain that are critical to orchestrating the body’s vital functions, while they shed cells to invade other parts of the brain, forming more tumors too small to detect using conventional imaging techniques. Brain cancer’s location and ability to spread quickly makes treatment with surgery or radiation like fighting an enemy hiding out among minefields and caves, and explains why the term “brain cancer” is all too often associated with the word “inoperable.”

Making treatment even more challenging, there is a system of blood vessels and protective cells in the brain — the blood-brain barrier — that admits only essential nutrients and oxygen, and keeps out everything else, including about 95 percent of all drugs. This natural barrier puts serious limits on how much a patient can benefit from traditional chemotherapy and new cancer drugs.

In an ideal situation, we would have a “smart” drug that could cross the blood-brain barrier, zero in on the cancer cells, mark their location clearly for surgery, or destroy them with such precision that it would leave surrounding, normal brain cells intact. Until now, such a scenario seemed so far-fetched. But using nanotechnology, NCI-supported researchers at the University of Michigan, the University of Washington, the University of Texas M. D. Anderson Cancer Center, Virginia Polytechnic Institute, and Virginia Commonwealth University are creating ultrasmall particles that can target and destroy cancer cells in the brain, even those in tumors too small to be removed surgically.

How can any of us tell you that?????????All you have to do is call the dr and ask him/her to set up an appt for you for either an MRI or CAT scan xray. Common sense should tell you this is the only way to be sure. It's probably nothing. If it IS a brain tumor, the soon they detect it the sooner they can get it out and you can go on living a noraml life. Chances are it's nothing but the only way to know for sure is to do what I told you.

There is not a cure to brain cancer.

There is not a cure for any cancer.

There have, however, been attempts at it, and I suppose you could type about all of the attempts at curing brain cancer.

You know, I am not really sure why anyone would honestly expect you to answer that on a test.
Bottomline, if someone knows what the solution is, then they are not sharing. WHY?...you might ask? BECAUSE people are still dying of it and do not know how to cure it.
There isn't a cure as of yet...period.

How can you just "not get" brain cancer? Lol.

A friend of mine never did anything wrong -- drink, smoke, etc. and yet she still got a brain tumor. She couldn't have just thought it away or just not gotten it.

cancer is basically a sort of dreaded disease. there is a cure for cancer but this is only at about the first or maybe second stage. this you should be asking a doctor and not us as we may have given you the wrong information.

Brain cancers are often untreatable.
