Radiation Therapy:
Using Targeted Energy to Treat Prostate Cancer

Radiation therapy uses high-energy beams to kill prostate cancer cells. It can be used as a primary treatment, after surgery, or for advanced disease to help control symptoms.

Types of Radiation Therapy

  • External Beam Radiation Therapy (EBRT), including IMRT and IGRT
  • Brachytherapy (internal radiation)
  • Stereotactic Body Radiation Therapy (SBRT)
  • Proton Beam Therapy (uses protons; availability is limited)

Some centers also offer focal treatments like high-intensity focused ultrasound (HIFU) or cryotherapy in select cases.

Who It’s For

  • Men with localized prostate cancer as an alternative to surgery
  • Men who are not surgical candidates due to other health conditions
  • Men with locally advanced or recurrent cancer, often with hormone therapy

Benefits

  • Non-surgical, outpatient in most cases
  • Comparable cancer control to surgery for many with localized disease
  • May preserve urinary and sexual function in some cases (side effects still possible)

Risks and Side Effects

  • Urinary frequency, urgency, or discomfort
  • Bowel changes such as diarrhea or rectal irritation
  • Fatigue during or after treatment
  • Sexual side effects, such as erectile dysfunction, which may develop gradually

Some advanced techniques may reduce certain risks, but side effects can still occur.

Recovery

Hospital stay is often 1–2 days, with catheter use for 1–2 weeks. Full recovery may take weeks to months.
