Introduction: Radiation therapy is the utilization of radiation in order to treat diseases like cancer as well as to detect other ailments that someone may have. Since the development of radiation therapy many advancements have been made both to the process of using radiation itself, which in turn increased its effectiveness for medical use, and to the study of other possible uses for radiation. The concepts behind radiation therapy are not overly complicated, but they are still revolutionary ideas that have greatly impacted society and people’s wellness. Development of Radiation Therapy: The beginnings of radiation therapy were a result of x-rays, first discovered by a German physicist named Wilhelm Roentgen in 1895. During experimentation with electricity, he found that certain types of energy were able to pass through his body and produce an image of his skeletal structure. Shortly after Roentgen’s discovery of how to produce x-rays, the medical potential of them was explored and used to diagnose health issues. The use of radiation was taken even further than x-rays by Emil Grubbe, who became the first radiation oncologist. Radiation oncology is the study of the therapeutic benefits of radiation. Grubbe earned this title because he was the first to propose using x-rays as treatment for breast cancer, and his experiment was accompanied by immense success. Many people followed Grubbe’s footsteps and became radiation oncologists. Methods for treatment improved in many areas from things like when dosage should be given, how much should be given per dose, and the ability to pinpoint and attack even the deepest cancerous tumors. After these improvements many radiation oncologists changed their focus to more specific treatments an... ... middle of paper ... ...ncer Center, 2014. Web. May 18, 2014. Frey, Rebecca J.

the effective doses from diagnostic CT procedures are typically estimated to be in the range of 1 to 10 mSv. This range is not much less than the lowest doses of 5 to 20 mSv estimated to have been received by some of the Japanese survivors of the atomic bombs. These survivors, who are estimated to have experienced doses slightly larger than those encountered in CT, have demonstrated a small but increased radiation-related excess relative risk for
According to Helibron and Seidel (2011) nuclear medicine began as a simple experiment in the early twentieth century by George de Hevesy. De Hevesy started the experiment by deciding to test the effects of radiation on living things, beginning with bean plants, then onto furred animals, and then continued onto finding the effects of radiation on the human body, when he did this he became the first person to ever use radiation on a human being. He along with his partner E. Hofer, in 1931, consumed Deuterium which they had diluted with tea and found that traces of radioactivity stayed within their bodies for between eight to eighteen days. This was the first known use of radiation on humans (p. 1). This was just the beginning though, as time moved on the use of nuclear energy advanced and as it advanced it began to bleed into more subjects than those that it had been used in before, such as, nuclear medicine. Although it has its drawbacks, such as nuclear waste, there are many different benefits to nuclear medicine. Examples of such would be advances in therapy and treatment of disease...
3. Stereotactic Body Radiation Therapy (SBRT) delivers small high doses of high radiation to a precise target within the body, and is usually considered for early stage lung cancer.
At this day in age we are constantly trying to improve the field of medicine in any way that we possibly can. We cherish every birthday and continually try to prolong life. Not only through every field of medicine, especially in terms of cancer. The American Cancer Society is “the official sponsor of birthdays” and is making leaps and bounds in the types of care that cancer patients receive. One of these many breakthroughs is the practice of Stereotactic (Body) Radiotherapy or S(B)RT. SBRT and other radiation therapies have the ability to greatly improve the way that we treat the issue of cancer and the variation of treatment options; however, they have raised the concerns of long term effects from radiation and cost-effectiveness. As research has begun to show, radiation therapies are having great success in curing cancer.
The most common type of radiation therapy that is used involves exposure of patients to external radiations. In this method, a beam containing high-energy X-rays is directed to a specific region of the body to irradiate the main tumors. However, the problem with this technique is that the ability to hit normal tissues of adjacent organs (Noda et al., 2009). Different from this, targeted radionuclide therapy functions like chemotherapy. A radionuclide labeled molecule is administered either orally or intravenously such that it delivers radiations that are sufficiently toxic to the site of the disease to kill the target cells (Bolus & Brady, 2011). However, the main difference with chemotherapy is that the drugs or toxins only...

Radiation therapy is a complex treatment plan to treat cancer in patients. Its treatment can be used alone or in conjunction with surgery or chemotherapy. Radiation therapy is delivered by a team of individuals who specialize in the treatment of cancer. There are several ways in which the radiation can be delivered to the patient with specialized equipment. Radiation therapy is an exciting field of study that can be beneficial to patients who are affected by cancer.
Radiation therapists work closely with patients to fight cancer. According to Health Care Careers, Oncologists, Dosimetrists and nurses are some of the professionals that a radiation therapist works with while caring for a cancer patient. This group of professionals will determine a specialized treatment plan. The first step usually includes a CT scan performed by a radiologist to find the exact area that needs to be targeted with x-rays. Next, the therapist uses a special machine that emits radiation called a Linear Accelerator. They use this machine during a treatment called external beam therapy. During this process, the Linear Accelerator will project x-rays at targeted cancer cells or tumors. Another therapist will be in a different room monitoring the patient’s viral signs until the procedure is over. The external therapy l...
There are ways to better understand how radiation affects the body when compared to other every day activities. If an occupational worker receives 1 rem per year then is it possible that 51 days is expected to be lost. A person that smokes 20 cigarettes a day takes about 6 years off of their life. People that are overweight by 15% take about 2 years off of their life. In actuality radiation would seem as though it is not any more harmful than other everyday activities people decide to do such as smoke, chew tobacco, or sky dive. The risk of taking days, weeks, years off of ones lives will always be present depending on the activity they choose to be part of. However, radiation exposure in the healthcare field is used to extend the patient’s life by helping them find out what is going on in their body. A patient that comes in with RLQ pain, nausea, and vomiting then an abdomen x-r...

How is radiation therapy being improved some might ask,"Doctors and other scientists are conducting research studies called clinical trials to learn how to use radiation therapy to treat cancer
Gamma rays can be used for many different applications, they could be of very little importance, or they could be life saving. One very important use for gamma rays is for cancer radiation therapy. Radiation therapy is a high radiation transmitted to the body to shrink tumors and kill cancer cells. The main type of radiation is using gamma rays. There are two other types; x-rays and charged particles. A machine outside of the body delivers the radiation. However in some cases it can be delivered internally through a radioactive material placed near the cancer cells. About half of all cancer patients receive some type of radiation therapy sometime, the course of their treatment.
The history of Nuclear medicine has a lot of importance and made a significant improvement to today’s medicine. Nuclear medicine has made genetic therapy a success and improved the rate of surviving cancer a lot more likely than before. There is no real birthdate for nuclear medicine according to medical historians and this is due to Nuclear medicine multidisciplinary nature. However, there is a given approximate range of its birthdate, which was between 1934 and 1946. In 1934, the artificial radioactivity was discovered, and in 1946, radionuclides were produced by the Oak Ridge National Laboratory for medical use. Through this article, the following would be discussed; the achievements and great discoveries that helped evolve Nuclear Medicine, the important uses for Nuclear Medicine, and the growth and expansion of Nuclear Medicine outside North America.
Nuclear medicine is the use of radioactive substances in the diagnosis and treatment of disease. Nuclear medicine records the radiation that is emitting from the body, unlike x-rays which determine the radiation emitted by external objects. Nuclear medicine scans show the function of anatomy and are known as a physiological imaging modality. The two most common forms of nuclear medicine are “SPECT” single photon emission computed tomography and “PET” positron emission tomography.
