A new MRI-guided ultrasound technique called TULSA has shown promising results in treating prostate cancer, eliminating clinically significant cancer in 80% of subjects in a one-year study. The minimally invasive technology uses a rod that enters the prostate gland via the urethra to emit highly controlled sound waves, heating and destroying diseased tissue while leaving healthy tissue unharmed. The treatment has been approved for clinical use in Europe and has received FDA pre-market clearance in the US. The study's results suggest that TULSA could be a safer and less invasive alternative to traditional treatments like surgery or radiotherapy.
