Welcome to HW.
A good URO would recommend some additional tests. Likely a repeat DRE to confirm. Possibly some imagining - MRI or CT - to see what it might be. Not all bumps are cancer, it could be a calcification (prostate stone) and harmless.
Your PSA isn't behaving like anything bad is going on. As we age PSA naturally increases.
A biopsy could be done to see what it really is. A URO might recommend that.
I'll be in the shop.
