LONDON—For decades, men diagnosed with prostate cancer have faced a difficult choice: risk the serious side effects of invasive treatments or live with the uncertainty of their disease. Now, a prominent surgeon in the United Kingdom is championing a more precise and less damaging alternative.
The technique, known as high-intensity focused ultrasound (HIFU), precisely targets and destroys cancerous tissue. It aims to spare patients the common consequences of prostate removal or radiation. These consequences can include lifelong incontinence and erectile dysfunction.
Hashim Ahmed, a urology professor at Imperial College London, is at the forefront of this movement. On a recent morning at London’s Parkside Hospital, he demonstrated the procedure. His patient was a fit, healthy 50-year-old man with a small but aggressive tumor.
In a traditional scenario, this patient might have undergone surgery to remove his entire prostate. Instead, Professor Ahmed used a different approach.

The patient was placed under general anesthesia. Professor Ahmed then inserted an ultrasound probe. He used live imaging to guide the device to the tumor. The tumor was just a10 millimeters wide, about the size of a pencil eraser.
The probe then delivered powerful, focused sound waves. These waves heat and destroy the cancer cells. The surrounding healthy tissue remains largely untouched. This precision is the core benefit of the treatment.
Professor Ahmed and his supporters argue that this method is more humane and effective for suitable patients. It offers a potential middle ground. Men may no longer have to choose between living with cancer or living with the severe side effects of its treatment.
The procedure is part of a broader shift in prostate cancer care. Doctors are increasingly moving away from one-size-fits-all treatments. They are now adopting more targeted therapies that prioritize a patient’s quality of life.
