Final answer:
A PSA level above 4.0 ng/mL should start to make you concerned. PSA levels above this threshold are generally considered to be elevated and may indicate a risk for prostate cancer. Consult with a healthcare professional for accurate interpretation and further testing if needed.
Step-by-step explanation:
A PSA (Prostate-specific antigen) level above 4.0 ng/mL should start to make you concerned. PSA levels above this threshold are generally considered to be elevated and may indicate a risk for prostate cancer. However, it's important to note that PSA levels can vary depending on age, race, and other factors, so additional testing and evaluation by a healthcare professional would be needed to make a definitive diagnosis.
For example, if a man is younger, he may have a higher normal range. If he is older, he may have a lower normal range. Additionally, certain medical conditions, such as benign prostatic hyperplasia (BPH), can also cause elevated PSA levels.
Therefore, it's crucial to consult with a healthcare professional to interpret PSA results accurately and to discuss further testing and treatment options if necessary.
