Literature The review of related literature in this chapter is composed of principles and discussions of facts about the side effects of radiation therapy to the cancer patients. The chapter begins with a brief history about radiology as a medical science‚ and radiation therapy as a form of medical treatment of diseases. Lastly it enumerates the side effects of radiation therapy and the risks associated with it. Brief History and Definitions of Radiology as a Medical Science In 1895 Roentgen began experiments

Brachytherapy (also known as internal radiation therapy) is the use of radioactive ‘seeds’ to help destroy cancerous cells. It is commonly used as a treatment for cervical‚ prostate‚ breast and skin cancer. How long the treatment will take will depend on where the tumor is and how large it is. Brachytherapy works from the inside of the body by placing the radioactive ‘seeds’ into the body next to the tumor. About 4/10 people with cancer have some type of radiation therapy as their treatment. History of

Radiation therapy (RT) is an essential component in the interdisciplinary treatment of brain tumors. Independently of histology‚ radiation plays a central role and has shown to increase local tumor control. Developments in radiation oncology are always aiming at an increase precision of dose delivery: More conformal coverage of target volumes‚ steep dose gradients to surrounding tissues‚ and sparing of organs at risk (OAR). In photon therapy‚ based on 3D-RT‚ stereotactic radiotherapy was a big step

including mammography) all use ionizing radiation to generate images of the body. Ionizing radiation is a form of radiation that has enough energy to potentially cause damage to DNA and may elevate a person’s lifetime risk of developing cancer. CT‚ radiography‚ and fluoroscopy all work on the same basic principle: an X-ray beam is passed through the body where a portion of the X-rays are either absorbed or scattered

Opportunities such as surgery‚ medicine treatments‚ and multiple therapy options. Radiation therapy has impacted many people’s lives just in the last few years. Cancer patients especially‚ have been given another chance at life through a few treatment rounds. In the past to remove cancerous tumors and small masses‚ surgery was the only option to improve those patients lives; with advances in technology and medicine‚ radiation therapy has become a very likely option for these patients.

Chapter 1 From X-Rays to Ion Beams: A Short History of Radiation Therapy James M. Slater Abstract Radiation therapy (RT) developed in several eras. Patients’ needs for more effective treatment guided the efforts. The development of ion beam therapy (IBT) can be seen as a corollary in this continuous endeavor to optimize disease control while minimizing normal-tissue damage. It could not have materialized‚ however‚ without the curiosity‚ ingenuity‚ and perseverance of researchers‚ engineers

What do cancer‚ radiation‚ and technology have in common? The links between the three are quite extraordinary. Cancer is a disease that accounts for 13% of all deaths in the world (Delfino and Day 1). The disease has an impact on patients‚ friends and their love ones. According to WebMD‚ radiation is energy that travels in the form of waves through radiation therapy. Through radiation therapy‚ radiation is used to stop‚ slow or cure the growth of cancer. With technology‚ radiologists can treat

Some of the greatest medical advancements in the modern age involve the use of many different types of radiation. Radiation therapy is used in treating multiple different types of cancer‚ and radiation from certain elements are put in X-ray tubes to save countless lives and prevent permanent injury wherever possible. Many organisations also use it for security‚ as well as the general use in the everyday home. These advancements and many more were based on the work of Marie Curie‚ renowned female

My grandfather was diagnosed with stage four colon cancer when I was nine years old‚ and was put through various stages of radiation therapy. This sparked my interest in the medical field. Ultimately due to my enjoyment of working with people facing difficult circumstances and helping them through the rough times I came back to Radiation Therapy. While my grandfather was administered the therapy‚ he met truly genuine nurses and caregivers

Monte Carlo simulation (MC). Particle interactions are the cause of everything we know to exist‚ such as the bright lights that illuminate the room you are in or the heat you feel when you stay in the sun for too long. To understand how these particle interactions occur we need to be able to simulate how they occur and study their effects with matter. Monte Carlo is a mathematical method to solving real world problems using probability; it can be used to determine the most probable trajectory that
