MRI targetter biopsy means you first do the MRI. Hopefully you locate the tumor or the suspected tumor, then biopsy those tissues. It saves a lot of pain and money. There had been reports that people went through multiple biopsies. Either nothing or low-grade cancer. But using this method, they got the cancer and had it treated effectively.
You might want to get a second opinion or go to one of the larger clinics that offer the treatment.
Dont mind me. I am just another layman trying to make some sense of the whole thing.
