Understanding PSA Levels and Prostate Cancer Screening
TLDR PSA levels in the blood can indicate prostate health and potential issues such as infections or cancer, with different tests like the 4k score offering more nuanced approaches to screening and predicting risks. Urologists use various methods to fine-tune the PSA test, making it more cancer-specific and helpful in diagnosing prostate cancer.

02:22
PSA levels in the blood can be used as a screening tool for prostate cancer due to leakage from the prostate as it grows and ages, making it a good biomarker for prostate size.
04:55
PSA levels can rise due to factors like prostate infections or cancer, with normal levels varying by age and a PSA above 2.5 often considered abnormal, potentially requiring further evaluation.
07:15
Different ways urologists use to fine-tune the prostate specific antigen test to make it more cancer-specific include looking at percent free PSA, PSA density, and absolute cutoffs for PSA levels.
09:55
The 4k score and the prostate health index test have revolutionized prostate cancer screening by leveraging the different ways prostate cancer cells produce PSA compared to benign cells.
12:28
The 4k score test provides a percentile chance of being diagnosed with high-grade aggressive prostate cancer, offering a more nuanced approach to screening.
14:44
The 4k score test can predict the probability of dying from metastatic prostate cancer in the next 20 years based on specific score thresholds.
