One study comparing prostate MRI to biopsy found MRI scans to correctly diagnose 93% of tumors, whereas biopsy correctly diagnosed only 48%. Identifying non-threatening forms of prostate cancer helps decrease the risk of overdiagnosis and overtreatment.
What is focal therapy prostate?
The idea of focal therapy is relatively new to prostate cancer but has become an accepted approach for treatments for other cancers. "The goal of focal therapy is to treat only the area with the most aggressive tumor, while leaving the rest of the prostate and its surrounding structures alone," says Derek J.
What is the procedure for prostate MRI?
Patients are placed under anesthesia for the procedure. For cryoablation and focal laser ablation, the ablation probes are placed through small needles inserted into the perineum. For high-frequency ultrasound ablation, the ablation energy is delivered through a transrectal ultrasound probe without the need for any needles.
Why is repeat prostate biopsy important?
Repeat prostate biopsy is also important if changes are seen on follow-up MRI or the PSA rises. If recurrent prostate cancer is found on follow-up, patients may have the option for repeat ablation or they can elect to have whole-prostate gland treatment in the form of radical prostatectomy or radiation therapy.
