A patient may receive radiation therapy before‚ during‚ or after surgery. Some patients may receive radiation therapy alone‚ without surgery or other treatments. Some patients may receive radiation therapy and chemotherapy at the same time. The timing of radiation therapy depends on the type of cancer being treated and the goal of treatment (cure or palliation). Radiation therapy given before surgery is called pre-operative or neoadjuvant radiation. Neoadjuvant radiation may be given to shrink a

The radiation protection to be practiced → cell phone radiation During normal use‚ over half of the radiation transmitted by your mobile phone is absorbed by your head or body. Around 80% of the phone’s microwave emissions are absorbed by the head. Only shielding or distance to the phone can reduce their severe impact. The United Nations World Health Organization has classified mobile phone radiation as possibly cancer causing and advise that it is important for mobile phone users to minimize

purpose is to provide information on cell phone radiation‚ the risks that can be caused by cell phone radiation‚ and the potential health problems that could result from this. Details of the topic: I am going to talk about the arguments about how cell phone radiation can affect our lives and whether these arguments are accurate or not. Cell phone radiation is a type of electromagnetic radiation that has the ability to cause health issues. The radiation from this device can cause serious brain tumours

As a radiation therapist there are many challenges faced. The most challenging obstacle for a Radiation Therapist is the communication between them and the patient. In most settings Radiation Therapist are working with patients who have been diagnosed with cancer and the main goal during treatment is the make their visit as comfortable as possible. By empathizing with the patient‚ building a trusting relationship with the patient‚ and supporting the patient the communication between the Radiation

EFFECTS OF RADIATION Background Radiation is all around us. It is naturally present in our environment and has been since the birth of this planet. Consequently‚ life has evolved in an environment which has significant levels of ionizing radiation. It comes from outer space (cosmic)‚ the ground (terrestrial)‚ and even from within our own bodies. It is present in the air we breathe‚ the food we eat‚ the water we drink‚ and in the construction materials used to build our homes. Certain foods

Adaptive Radiation Adaptive radiation occurs most often in new environment with a variety of different unfilled niches so that plants and animals that are not adapted to those areas can exploit the resources in the respective niches. Once individuals begin exploiting the new niches‚ mutations that will benefit the species will spread throughout the population via natural selection giving the owners an overwhelming advantage over others without the mutation and throughout evolutionary time

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
