How Does Radiation Therapy Work?

• Also called radiotherapy, this treatment beams doses of radiation that are many times more powerful than an x-ray at the affected area. Doctors use extreme precision to target and kill cancer cells and shrink tumors.
  
  

Uses

• When a cure is impossible, radiotherapy is used to mitigate the effects of cancer. It is used in the treatment of prostate cancer, stomach cancer, early stage breast cancer and early stage lung cancer
  
  

Radiotherapy Procedure

• Doctors are careful to limit the dosage and damage to healthy cells. Treatments are divided into small sessions called fractions. The typical treatment period lasts five days.
