Radiation therapy is a growing field that has not been around very long. This field works with patients that have many different types of cancer ranging from leukemia, lung cancer, prostate cancer, cervical cancer, and brain cancer among others. Cancer can be effectively treated using surgical, chemical and radiation treatment or a combination of the three. Many advantages and disadvantages have emerged when considering the use of radiation therapy and these pros and cons should be discussed thoroughly between the Oncologist and patient before a decision has been made on a course of action. Special licensing is required to enter this specialized field of radiation therapy and can be obtained through special programs.
There are many different

According to the American Cancer Society, many side effects to radiation therapy occur because normal, healthy cells near the treatment area may become damaged. Temporary side effects may include fatigue, skin changes, hair loss, low blood counts, and eating problems. Longer-term disadvantages to radiation therapy consist of potential damage to the tissue, glands and organs near the vicinity of the tumor, the incapacity to destroy tumor cells that remain undetected on imaging scans, the inability to destroy all cancerous cells in the tumor, infertility, scar tissue growth and more. Unfortunately, when radiation therapy is solely used on particular types of cancers, it may not be entirely successful. This rings true especially for specific cancers that have …show more content…
Radiation Oncologist Dr. Peter Rossi who specializes in prostate cancer treatment wrote about some of the advantages of radiation therapy. These advantages encompass the death of a profound volume of cancerous cells, eradication of microscopic disease at the perimeter of the tumor, the capability to shrink tumors, cooperative interaction with systemic therapy, preservation of one’s organs, the stimulation of an immune response against the tumor, and a relatively safe and painless treatment for the patient
Exercise science possess many traits that attracted my attention whether it dealt with the different job opportunities or the ability to help an individual. There are two areas of exercise science that one can choose as a possible career path or as a major minoring in something else related to this type of work. One of the areas of study includes exercise physiology which can be defined by “the study of how the body’s structures and functions are changed as a result of acute and chronic bouts of exercise”. Not only does exercise physiology promote a healthy lifestyle, but it is closely connected to human performance, fitness, development/aging, and prevention/rehabilitation from disease or injury. Pursuing a degree in exercise physiology allows an individual in this profession to choose between several careers including physical education, exercise science and athletic training (Fisher, 2). In addition, becoming a chiropractor can be achieved through exercise science.
The current standard of therapy is resection of the tumor plus radiotherapy and TMZ (E5). Multiple studies performed between 1976 and 1991 have led postoperative radiotherapy to be accepted as standard treatment (L12). The universal dosing schedule for radiotherapy in GBM is fractionated irradiation over 6-7 weeks for a total of 60 gray (Gy) (G7,M13). TMZ is an oral alkylating agent that can be used concomitant with radiotherapy and as an adjuvant. The European Organization for Research and Treatment of Cancer (EORTC) and the National Cancer Institute of Canada (NCIC) organized a study showing that adding TMZ to standard radiotherapy is beneficial to overall survival. This study enrolled 573 patients from 85 institutions and randomly assigned eligible patients to receive either standard radiotherapy alone or radiotherapy plus concomitant and adjuvant TMZ. There was a 37% decrease in relative risk of death and a median increase in survival of 2.5 months in patients treated with TMZ and radiotherapy when compared to radiotherapy alone (P<0.001). There are adverse effects with both RT and chemotherapy, but hematologic toxicities are more likely to occur in patients treated with both TMZ and RT (M13). This study maintained its validity after accounting for recursive partitioning analysis classifications (L12). The current standard dose of TMZ is 75 mg per square meter of body surface area daily during radiotherapy and then a dose of 150-200 mg per square meter of body surface area for 5 days of each 28-day cycle following RT (G7,M13).
Radioactive Waste One of the most talked about opposition to nuclear fission is the radioactive waste it produces. Radioactive waste is what is left behind after using a reactor to make electricity. There are two levels of waste, low and high, but both are regulated by the Department of Energy and the Nuclear Regulatory Commission. High level waste is made up of fuel that’s been used directly in the reactor, which is highly radioactive but can still be disposed of. Low-level waste is the contaminated items that have been exposed to radiation.
2. External Beam Radiation Therapy (EBRT) which is usually offered when the lung cancer is either considered to be primary, or when it has metastasized (spread to other organs). This form of treatment uses a linear accelerator machine to focus a precise beam of radiation on a given area of the body for a precise period of time to kill off cancerous cells.
Since the beginning of the propitious world, the core aspect that keeps it thriving is the propensity for people to discover innovations; however, progress of the past is, systematically, detrimental to the future. Not long after the revolutionary invention of the X-ray in the late 19th Century, an unprecedented number of medical examiners noticed (unknown to the time) radiation burns all over their body; decades later, an extraordinary surge in cancer cases had arisen. Perhaps, during the course of these years, scientists and researchers desired to further progress the x-ray (into the immense subsidiaries that are here today), and disregarded any flaws in the apparatus. This systematic inclination continues into the present time as Gary Marshall and Shane Keene notes in their 2007 article, “New technologies allow for patients to be overexposed routinely, and also allow for repeats to be taken quickly, making it easier for a technologist to multiply the patients dose without considering the implications” (5). The gaffes of radiology are present not only in the diagnostic setting, but also in the surgical and therapeutic areas. Working with radiation, it is imperative that the staff is aware of mistakes that are potentially fatal not only for patients, but themselves. It is especially important for medical radiologists to be cognizant of pediatric patients. The standard practice of pediatric radiology in the United States is to follow the step-by step formula from which adult patients are treated and diagnosed. There are copious consequences for following this technique since a child naturally has less body mass and a weaker immune and lymphatic system to manage radiation and its adverse effects. Medical radiology, being a...
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.
Cancer is a disease in which cells multiply out of control and gradually build a mass of tissue called a tumor. There has been a large amount of research dedicated to the treatment and cure of cancer. Several types of treatments have been developed. The following are just some of the major examples of cancer therapy: surgery, chemotherapy, radiation therapy, biologic therapy, biorhythms, unconventional treatments, and hyperthermia. Each type of treatment is discussed in detail below.
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.
...effects that can come with chemotherapy such as nausea, vomiting, hair loss, fatigue, mouth sores, and more. Radiation therapy is pretty bad but not as painful with side effects. Side effects for radiation therapy are coughing, fever, fullness of chest, soreness and scaring. Many times surgery is not an option but when is it is one of the best options due to the fact there are less side effects and no strenuous treatment. One of the reasons cancer is such a bad thing is because the treatment is not good but research is taking place and working to get more effective.
Surgical castration is the most cost-effective treatment for prostate cancer, but it is not the choice of many. A new method is to target a beam of high-intensity ultrasound at the prostate. This may destroy cancer cells, and have few side effects. However, there have only been preliminary studies, so evidence is not conclusive. Another method being tested is implanting radioactive seeds into the prostate. This method is called brachytherapy, in which pellets smaller then grains of rice are inserted into the prostate. Preliminary studies show much success, and it is believed that this method can be better then surgery.
According to SEER Statistics, 23,380 people are estimated to get a brain or nervous system cancer diagnosis. Out of those people, 14,320 people are estimated to die from their brain or nervous system cancer diagnosis (National Cancer Institute). Cancer is a type of dangerous tumor, or a buildup of extra cells that form a mass of tissue, that can be life threatening (National Cancer Institute). The term for a tumor that is cancerous is a malignat tumor, whereas a benign tumor does not contain cancer cells (National Cancer Institute). According to the National Cancer Institute, the causes of brain cancer are unknown, but risk factors include family history and excessive radiaton exposure. Although they are not always due to a brain tumor, comon symptoms include headaches, nausea, speech, hearing, vision, and mood changes, problems with balance and mamories, seizures, and numbness in arms and legs (National Cancer Institute). MRI and CT scans as well as surgical biposies (or the removal of part of the tumor to be examined) are used to diagnose brain cancer (National Cancer Institute). Different types of treatment options include radiation therapy, surgery to remove the tumor, and chemotherapy. According to Charles Davis, MD, PhD and Nitin Tandon, MD of WebMD.com, chemotherapy is “ the use of powerful drugs to kill tumor cells”. There are a few different types of chemotherapy, but all of which bring out the same kinds of side effects. Although the physical side effects of chemotherapy are commonly known, few people know of the emotional toll chemotherapy can take on a patient and his or her family as they go though this process.
Individuals who go through the process of becoming a chiropractor are dedicating their lives to improve others through their own hands. Giving a patient relief and satisfaction without harming their body with drugs that can have horrible side effects is a feeling that is unlike anything else. Facilitating an individual to heal and strengthening their life entirely is what chiropractors strive for and many accomplish that ambition. Additionally, studies and surveys have shown why students of chiropractic chose this profession. The top reasons were that they truly want to help people and heal them, the increase in financial status, and the ambition of having the title “Doctor.” (Wardwell 154). Chiropractors must complete many demanding courses
The energy in ionizing radiation can cause chemical changes in the the cells that can lead to damaging them. Most of the cells can either permanently or temporarily become abnormal or they can just die. Radiation can cause cancer by damaging the DNA in the body. The damage of the cells can also depend on how long the organs are exposed (environmental protection agency, 2017, unknown). If someone has many exposures at one time that radiation in the body keeps adding on. As well as if its only a little bit of exposure in on day and years later you get exposed again it keeps adding on the radiation will never leave the body. Having radiation in your body doesn’t affect you right away but as you get older it starts to show and you feel it. Chronic exposure is when someone is exposed many time for long periods. When this happens the type of effects it will carry is having harmful generic change, cancer, tumors, and even cataracts. Partial health effects can also depend on if it was internal or external exposure. Internal exposure is when either by drinking, breathing, eating and even an injection cause radiation to get inside your body. External exposure is when taking an x-ray out of your body and letting it go through letting all the energy go as it goes in (environmental protection agency, 2017, unknown). In the dental world radiation gets into the patients when we take x-rays on there teeth. In order to avoid to much radiation on them we put a lead apron on them and make sure to cover their thyroid which is the most common way of getting cancer when taking an x-ray. When we take the x-ray we stand behind a wall at least 6 feet away to avoid ourself from getting
There are also several very important steps you can take to help reduce the damaging effects of both chemotherapy and radiation therapy to your skin.
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
