Understanding PSA, PIRADS, Tumor Size, & Location | Answering YouTube Comments #59 | Mark Scholz, MD

Mark Scholz, MD, is a medical oncologist who specializes exclusively in the management and treatment of men with prostate cancer. Here, he answers patients' questions from our YouTube comments on the relationship between MRIs and biopsies.

0:09 I am 74 years old and have a PSA between 3.9 and 4.2. I had an MRI with a PI-RADS 5. Should I get a biopsy or recheck my PSA?

2:42 How does the PI-RADS system work?

4:56 Are lower-grade tumors like Gleason 6 usually smaller than higher-grade aggressive tumors?

6:38 What is the significance of the number of cores positive, and does it matter where the cores are positive (e.g., anterior vs. posterior parts of the prostate gland)?

7:45 Do tumors tend to grow in certain areas of the prostate gland?

8:52 How often do you suggest second opinions on biopsy reports? Are there certain criteria that would cause you to suggest seeking a second opinion?
