There is not too much information to go on there. I am going to take a guess the category 3 means a PIRADS score of 3. This is a scale which runs from 1 to 5. A score of 5 would mean cancer quite likely, and a score of 1 means cancer unlikely. So 3 is about the middle.
I'm going to assume you meant PSA not PDA.
PSA is not a very good test of cancer, and people with big prostates can have a high PSA just because the prostate is big. By taking the blood PSA and dividing by the prostate volume, you can get the PSA density. A value of 0.1 would be quite healthy 0.24 is a little high.
I presume the next action is to decide whether a biopsy is needed.
