Were you told that PSA levels below 4 are normal. What urologist and PCPs look at are rising numbers over time.

WOW your barely moved in 5 years. And you stated that you have prostate troubles which could explain even your 2.3.

For my experience I had a .75 PSA for many years. Then in 2017 started to rise. It kept rising and rising year after year so when it got to 3.75 in 2023 PCP refers me to urologist. Tests, biospies, then prostate cancer diagnosis.

We can't give you medical advice but seems like your PCP is following you closely.
