As someone with low-grade prostate cancer, the thing I'm most hoping for (for now) is better imaging or other monitoring tools since I'm looking at getting a biopsy every other year or so. The biopsy itself isn't too bad as far as medical procedures, but each one has a risk of infection so I wish there were a less invasive way. I'll get MRI's too, but they don't work as well at detecting small cancerous areas, my MRI missed the cancer that a subsequent biopsy found. Though I also wouldn't mind targeted immunotherapy that could target the cancer without any invasive procedures, chemicals or radiation.
