How Many Radiation Treatments for Prostate Cancer in 2025?
Radiation therapy remains one of the most effective and commonly used treatments for prostate cancer. The exact number of sessions depends on cancer stage, tumor aggressiveness, patient health, and the type of radiation chosen. Modern advancements have significantly reduced treatment duration while maintaining excellent outcomes.
Types of Radiation Therapy for Prostate Cancer
Two main approaches are used:
- External Beam Radiation Therapy (EBRT) – Delivers radiation from outside the body using a linear accelerator. It is non-invasive and highly precise with image-guided and intensity-modulated techniques (IMRT/IGRT).
- Brachytherapy (Internal Radiation) – Places tiny radioactive seeds directly into the prostate. It can be low-dose-rate (permanent seeds) or high-dose-rate (temporary placement).
Standard vs Modern Radiation Schedules: How Many Sessions Are Actually Needed?
- Conventional EBRT: 38–44 fractions (sessions) delivered daily over 7–9 weeks.
- Moderately Hypofractionated EBRT: 20–28 fractions over 4–6 weeks (now widely adopted as standard of care).
- Ultra-Hypofractionated (SBRT/Stereotactic Body Radiation Therapy): Only 5 fractions, typically given every other day over 1–2 weeks.
- Low-Dose-Rate Brachytherapy: Single outpatient procedure (seeds stay permanently).
- High-Dose-Rate Brachytherapy: Usually 1–4 sessions as monotherapy or boost.
Major guidelines (NCCN, ASTRO, NICE) now endorse 5–28 fraction regimens as equally effective and safe compared to old 8–9 week schedules for most low- and intermediate-risk patients.
Factors That Decide Your Radiation Treatment Count
- Gleason score and PSA level
- Tumor stage (localized vs locally advanced)
- Risk group (low, favorable intermediate, unfavorable intermediate, high risk)
- Prostate size and urinary function at baseline
- Patient preference and lifestyle (fewer visits = less disruption)
Real Patient Experiences in India
Rajesh, 64, Mumbai – Chose 28-fraction moderate hypofractionation; completed treatment in 5.5 weeks with mild fatigue only.
Vikram, 59, Bangalore – Selected 5-session SBRT because of work commitments; back to office in 10 days.
Suresh, 70, Chennai – Underwent single-session low-dose-rate brachytherapy; discharged the same day.
Evidence Behind Shorter Radiation Schedules
- The landmark HYPO-RT-PC trial (Lancet 2019) and PROFIT trial (JCO 2017) proved ultra-hypofractionated 5–7 fraction regimens are non-inferior to conventional 39-fraction schedules.
- CHHiP trial (Lancet Oncology 2016) established 20 fractions as safe and effective.
- Long-term 2024–2025 follow-up data continue to show equivalent cancer control and similar or lower late side effects with shorter courses.
Common Side Effects and Recovery Tips
Short-term (during and up to 3 months):
- Fatigue
- Frequent or urgent urination
- Mild rectal discomfort
Long-term (after 6–12 months):
- Possible erectile dysfunction (30–50% risk, lower with modern techniques)
- Slight risk of bowel or bladder changes (under 5% grade 2+ with IMRT/SBRT)
Recovery tips:
- Drink 2–3 liters of water daily
- High-fiber diet and stool softeners
- Pelvic floor (Kegel) exercises from day one
- Regular walking to combat fatigue
