Open Question

.What is radiation therapy?

In General Health Care
  

    




Radiation therapy is mainly used after surgery for tumors that cannot be removed completely, as well as for cases in which surgery would involve too great a risk to the patient. It may be given in a single dose each day, usually for 30 days with weekends off, or it may be "hyper fractionated" into two or more doses daily for the recommended course of treatment.

Standard radiation therapy delivers an external beam of radiation aimed at an entire region, such as the portion of the brain containing the tumor and typically delivers a daily dose of 1.8-2.0 Gy (Gray) to a total dose of 50-60 Gy over 5-7 weeks.
