What are the general guidelines of 3-D conformal radiation therapy for prostate cancer?

ANSWER

Here's how 3-D conformal radiation therapy works:

  • All patients have a CT scan specifically for radiation therapy treatment and planning.
  • The CT data is electronically transferred to the 3-dimensional treatment planning computer.
  • The doctor defines the area to be treated along with surrounding areas, such as the bladder, rectum, bowel, and bones.
  • An optimal radiation beam and dose are analyzed using a 3-dimensional computer-generated model.
  • When the exact dose of radiation to the prostate is determined, the patient returns for a treatment simulation.
  • The simulation process transposes or maps the computer-generated plan to the patient. The doctor will review the treatment course and side effects with the patient.
