Is there a correlation between the size of a lesion and Prostate cancer?

On January 25 of this year I had my yearly physical and the discussion of my annual blood work. Since my PSA had gone from 3.52 to 3.58 to 4.08, plus the fact that my father passed away due to PCa, it was decided to go for an MRI to see if we were dealing with anything serious. The MRI showed a PI RADs 4 lesion that was 1.2 cm. wide. Since my Prostate was measured at like 4.5 x 3.2 cms. wide it would make my lesion around 1/4 the size of my Prostate. I am now scheduled for a biopsy in a couple of weeks. My question is...does the size of one's lesion/lesions correlate at all as to whether it could be cancerous or benign?
