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

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

goal is to attend college‚ and become a Radiation Therapist. 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

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

Radiation treatment is the 2nd most common form of cancer treatment‚ next to surgery. The National Cancer Institute estimates that over half of all cancer patients receive radiation treatment sometime over the course of their illness (Radiation Therapy and You 2). It can be used alone to fight cancer or can be used in combination with surgery or chemotherapy. Radiation therapy

Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells. X-rays‚ gamma rays‚ and charged particles are types of radiation used for cancer treatment. The radiation may be delivered by a machine outside the body called a linear accelerator to focus x-rays directly on the tumor or tumor bed (external-beam radiation therapy)‚ or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy‚ also called brachytherapy).
