|Radiation therapy is a one way of cancer treatment. It uses high doses of radiation to kill cancer cells and stop spreading the destruction of new healthy cells. Mostly this therapy is useful to all cancer patients. The radiation may be external, from special machines, or internal, from radioactive substances that a doctor places inside your body which creates a radioactive pathway. Radiation therapy can damage normal cells as well as cancer cells. Treatment must be carefully planned to minimize side effects of the radiation. Common side effects include skin color changes and fatigue. Other side effects depend on the part of your body being treated.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
