Treatment Overview
About MRI Focal-boost Prostate Brachytherapy
Standard brachytherapy treats the whole prostate, but we now know that most cancers have a "dominant" area where the most aggressive cells live. MRI Focal-boost Brachytherapy uses your MRI scans to identify this exact "hotspot."
By using thin needles to place radiation directly into the prostate, we can give a much more powerful dose to the tumour itself while keeping the rest of the prostate at a standard, safer level.
This is a comprehensive treatment which combines the benefits of lesser side-effects of focal treatments with a cure rate of other radical treatments like surgery or radiotherapy.
This is a cornerstone of the NHS National Cancer Plan, moving away from "one-size-fits-all" treatments toward a plan that is unique to the map of your specific cancer.
Safety Information
Benefits, Risks & Side Effects
01
Benefits
The primary benefit is extreme precision. We can deliver a dose of radiation to the tumour that would be too high to give to the whole gland safely. This "escalated" dose is proven to be more effective at stopping the cancer from returning. Using this focal approach we minimise side-effects comparable to focal only therapies whilst still treating the whole prostate avoiding recurrence.
It is a day-case or one-night stay procedure, meaning you avoid major surgery and a long hospital recovery. For many men, it provides the "best of both worlds": the high cure rates of radiation with a significantly lower impact on their daily bladder and bowel habits.
02
Risks
The main risk is urinary retention (being unable to pass urine) shortly after the procedure because the prostate can swell from the needles. This happens in about 5% of cases and usually requires a temporary catheter for a few days.
There is also a small risk of infection (prostatitis), which we prevent with antibiotics.Because the "focal boost" is so targeted, the risk of long-term bowel damage is lower than with older methods. However, there remains a very small chance of persistent bowel urgency or minor bleeding.
03
Side Effects
In the short term, you will likely feel some soreness between your legs and may see a small amount of blood in your urine—this is normal and expected. You may find yourself running to the toilet more often or feeling a "burning" sensation when you pee for a few weeks.
Long-term, as with all prostate treatments, there is a risk to sexual function.However, by "focal boosting" only the tumour area, we aim to spare the delicate nerves that control erections, giving you a better chance of maintaining your quality of life compared to full-gland surgery.

Patient Journey
What to Expect
A step-by-step guide through your MRI Focal-boost Prostate Brachytherapy journey—from preparation and what happens during the procedure to recovery and aftercare.
01/ 03
Before Procedure
A few weeks before, you will have a Volumetric MRI or "Mapping Scan" to create your treatment blueprint. You may be started on a short course of hormone therapy to shrink the prostate, making the cancer easier to target.
On the day of the procedure, you will have an enema to ensure your bowel is empty; this helps the clinical team get the clearest possible ultrasound images during the operation.
02/ 03
During Procedure
You will be under a general anaesthetic (fully asleep). While you are asleep, the oncologist uses live ultrasound fused with your previous MRI to guide several thin, hollow needles through the skin between your legs (the perineum) into the prostate.
If you have High-Dose Rate (HDR): A radioactive source is pulsed through these needles for a few minutes and then removed.
If you have Low-Dose Rate (LDR): Tiny permanent "seeds" are left inside.
The "boost" is achieved by placing more seeds or leaving the HDR source longer in the exact spot your MRI showed the cancer was most aggressive.
03/ 03
After Procedure
You will wake up with a catheter in your bladder, which is usually removed before you go home or the following morning.You can return to light activity within 2–3 days, but you should avoid heavy lifting or cycling for about 4 weeks while the area heals.
You will have a follow-up PSA blood test in 3 months. Because the boost is so targeted, your PSA should drop steadily, which is a key sign the treatment has been successful.

Not at all. The 'focal boost' is an extra dose of radiation on top of a standard dose that still covers the whole prostate.We treat the whole gland to make sure any tiny, microscopic cells are cleaned up, but we give the 'boost' to the main tumour to make sure the 'engine' of the cancer is fully destroyed.

This depends on the type. If you have HDR (temporary), the radiation is removed before you wake up—you are never radioactive. If you have LDR (permanent seeds), you will be slightly radioactive for a few months. In 2026, the advice remains to avoid having children sit on your lap for long periods for the first two months, but "brief contact" like a hug is perfectly safe. Your team will give you a specific safety card to carry.

Yes, this is often used as a 'Salvage' treatment.If cancer returns after previous radiotherapy, a 'focal-boost' approach is often the safest way to re-treat the area without causing too much damage to the bladder and bowel.It’s one of the most effective ways to manage a recurrence in 2026.
