Cancerous tumor cells can be treated by high energy or?
Gamma rays, X-rays:
What type of surgery is done to correct a pituitary tumor?
If the tumor is small, surgery may be done through the nose. If the tumor is large, it may require opening the skull for tumor removal. Selected patients do well with proton beam radiosurgery
Is or is not a gamma ray a friend to the needy?
Yes! If you are needing treatment for a brain tumor or some other such malady.
What does gamma knife surgery fix?
Gamma knife surgery is a procedure in radiology using gamma ray beams to remove rumors and lesions in the brain. With this procedure they don't have to even cut one open; They just focus the gamma rays at the tumor to remove it from the brain in a very precise manner.
How does gamma ray therapy not harm patients?
Gamma rays are harmful, but the point is that the treatment should harm the cancer tumor more than it does the general health of the patient, so that there is an overall benefit.
How is cancer treated in a technique called teletherapy?
a narrow beam of high-intensity gamma radiation is directed at cancerous tissue
Why does the radiation for cancer treatments comes in many different beams from many different directions toward the body instead of just one beam aimed toward the tumor?
This is done to try to protect the person receiving the beams. The radiation needs to be strong enough to kill the tumor cells. This is also strong enough to kill healthy cells. If they just shot a single beam of a high enough intensity in, it would kill the tumor, but it would also kill the healthy cells in front of the tumor. By using separate beams, they can make each one weak enough to not kill the healthy cells, but where the beams cross at the tumor, the combined strength is high enough to kill the tumor cells.
Why are proton rays used?
The advantage of using proton rays is that they can be shaped to conform to the irregular shape of the tumor more precisely than x rays and gamma rays
What is the purpose of radioactive implants?
With the use of radioactive implants, the tumor is subjected to radioactive activity over a longer period of time, as compared to external beam therapy.
What does electron beam therapy use?
It uses high energy, penetrating waves or particles such as x rays, gamma rays, proton rays, or neutron rays
Why does the beam on a gamma ray have to be narrow?
Because otherwise it would kill more cells than it needs to and may harm the person, it would destroy the healthy cells
Will a gamma ray burst end the world?
There has been some speculation that a gamma ray burst has affected life on earth at one or more intervals in the past. And it is possible for it to happen in the future. For a gamma ray burst to destroy earth, the source would have to be moderately close, and because one characteristic of the gamma ray burst is that the emitting body directs two separate "rays" out in opposite directions. We'd have to be exactly in the wrong place at the wrong time and end up on an axial alignment with the gamma ray beam. As the beam is of short duration, the earth would shield a portion of life from its direct effects, but the destruction (ionization) of our atmosphere by the high radiation could burn the entire surface of the planet. Even on the "back side" away from the direction the beam originated in. This could happen, but will it happen? It's an event of low probability. Not that anyone will be spared if we "win the lottery" and get tagged.
