You have a very low PSA not something that would be a concern normally. Yes, having a relative with prostate cancer is a real indicator that you have a higher chance of getting it.

Has your doctor done a digital rectal exam to see if your prostate has anything noticeable in it? That’s the simplest test and can eliminate concern for now.

You have a very slow rising PSA. Yes, if it Hits .4 an MRI would be very advisable since you have a family history.

I don’t think your doctor is under estimating your chance of prostate cancer, at this time.
