Cancer is the form of disease, when abnormal cells divide uncontrolledly and invade other tissues. Cancer is not one type of disease because there are more than 100 types of the cancer spread in the world ( National Cancer Institute 2013). Every third person in the world has a cancer. Based on statistics, in the USA in 2013 the cancer was a cause of death for 580,350 people ( The American Cancer Society 2013). The aim of this project is to evaluate all aspects of proton therapy. It will be argued that proton therapy is the most effective treatment for cancer conventional treatments. The most established types of cancer treatment such as chemical therapy or chemotherapy and surgery will be discussed. The proton therapy as a contemporary type of radiation oncology, which is used in only a few countries, will be analyzed as a possible replacement. In this essay advantages of proton beam therapy such as cosmetic purity of a skin, efficiency and radiation will be discussув. Furthermore, in this paper will be evaluated the cost and risk of death, which can be reached by unprecise planning, of the proton beam therapy. Additionally, will be surveyed the results of the proton therapy such as treatment for earlier incurable types of cancer and possible discussed about future improvements.
The method to use protons such as medical treatment of cancer was proposed by Robert Whilson, who was fade American physicist, in 1946 (McDonald and Fitzek 2010, 257). He argued that the unique physical properties of protons are relevant to utilize this radiation techology in medicine. The principle of the proton beam therapy consists in the appreciable mass of protons than other particles; as a result, the beam slightly broaden and stays focused on the c...

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
Pediatric oncology has been so very rewarding in many ways, but also so very cruel in a few ways. The good days are great, but the sad days are heartbreaking. But beyond the death and the suffering, there is a whole other layer of
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.
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.

Computed tomography (CT) and Radionuclide imaging (RNI) are both a form of diagnostic imaging. Since they have been first introduced in medical imaging they both suffered a huge development over the years in terms of image acquisition and also patient radiation protection. The following essay it is going to focus on just a few important things that make CT and RNI similar and different in the same time. However this subject can be discussed in much depth, the focus is going to be on the similarities and differences of the physics imaging methods and also a small awareness of biological effects and radiation protection.
The Therac-25 was released to market in 1983 and is still in use today (ComputingCases). “Between June 1985 and January 1987, six patients were seriously injured or killed by unsafe administration of radiation from the Therac-25 medical linear accelerator” (Death and Denial).
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...
The prognosis (chance of recovery) and treatment options depend on where in the body the tumor started, the width of the tumor when the cancer was diagnosed, whether the tumor has spread to nearby lymph nodes or distant parts of the body, whether there are certain changes in the genes, the type of rhabdomyosarcoma, whether the tumor has been completely removed by surgery, whether the tumor responds to chemotherapy and/or radiation therapy, the patient’s age and general health, and whether the tumor has just been diagnosed or has recurred )come back). For patients with recurrent cancer, prognosis and treatment depend on where in the body the tumor recurred, whether the tumor was treated with radiation therapy, the size of the tumor when the cancer was diagnosed, and how much time has passed between the end of cancer treatment and when the cancer recurred.

No matter who it happens to, any type of cancer is heart-breaking. However, one’s heart seems to crack a little bit deeper when you hear a child has been diagnosed. Several forms of cancer can arise during childhood. The most common is acute lymphoblastic/lymphocytic leukemia (ALL). In fact, it is so common between the ages 0-14, that people refer to it as childhood acute lymphoblastic leukemia (Kanwar, 2013). .

How does one see the symptoms for childhood cancer? First one must know that there are many different types. There are forty different types of children’s cancer, including: Leukemia, Lymphoma, Sarcomas, cancers of the nervous system, liver cancers, kidney cancer, and more. Out of these cancers, the two most common childhood cancers are Leukemia, and brain tumors. What is leukemia? It is a cancer in which the bone marrow and other organs that produce blood produce and increased amount of immature or abnormal white blood cells. The symptoms of leukemia are paleness, excessive bruising, pain in the joints, and fatigue. Brain tumors are formed when a massive amount of cells are produced on the brain. The symptoms for this are frequent headaches, vomiting, seizures, decreased coordination, weakness, and problems concerning vision.
The recognition given to work with light based therapies by the Nobel Prize committee was in part responsible for the global rise of heliotherapy. By this time heliotherapy had a large enough audience to warrant interest in New York State Journals. One physician, Dr. Grasso, in an article in the New York state Journal of Medicine in 1992 described the advent of Heliotherapy in the state 1920’s. He mentions the work of Dr. Rollier who “introduced it [heliotherapy] on a large scale and on a sound scientific basis”.(Grasso 19...
Radiation is part of our life, so researchers have focused on studying the photon interaction parameters with matter (attenuation coefficients). This is due to increasing the use of radioactive sources in different fields such as medicine, tomography, and nuclear research applications. The attenuation coefficient is an important parameter to characterize the penetration and diffusion of gamma rays in matter. The absorbed and scattered ra...
