Stereotactic Radiation Therapy (SRT)

Context (TH): SRT has emerged as a potential treatment option for prostate cancer that has metastasized, or spread, to other areas of the body.

About Prostate Cancer:

• Prostate cancer originates in the prostate, a small, walnut-sized gland in men that plays a role in seminal fluid production.

Overview of Stereotactic Radiation Therapy (SRT):

• Definition: SRT is an advanced radiotherapy technique delivering high doses of precisely targeted radiation beams to eradicate cancer cells while minimizing damage to surrounding healthy tissues.
• Benefits Over Traditional Radiation Therapy:
  • Treatment Efficiency: SRT can address cancer in fewer sessions (typically one to five sessions over one to two weeks) versus conventional radiation therapy, which often requires 20 to 40 sessions over several weeks or months.
  • Reduced Side Effects: SRT has been shown to have a lower impact on sexual function compared to prostatectomy (the surgical removal of the prostate).
