Hi Doc! Good day! My dad was diagnosed and confirmed with prostate cancer last Dec 2017 with Gleason Score 7. Prognostic Grade Group 2 and based on his ultrasound scans he has concretions with the enlarged prostate. What does the concretions mean? Is it more of a mass that should be taken out through surgery? What treatments should my dad undergo? He is currently into alternative medicine (natural healing approach - through organic and healthy foods). Anything you may suggest? Thank you.
