Screening Prostate Cancer from your Pee
Prostate cancer is the most common cancer amongst men, accounting for 26% of all new cancer cases. Like breast cancer, it has started to receive a lot of attention in an effort to inform and educate men about this condition. However, unlike breast cancer, trying to identify signs and symptoms early can be difficult. Women often undergo regular screening above the age of 50 with mammograms, and women can be taught to self examine.
Prostate cancer on the other hand, is not so easy to screen. Examination via a rectal exam is invasive, and maybe embarrassing for many patients. There is a blood test that collates to the prostate, known as Prostate Specific Antigen (PSA), and looking for a rise in the PSA can indicate malignancy. Unfortunately, its accuracy is as low as 30%, as many activities can cause a rise in PSA, even cycling. And it is not specific to Prostate Cancer, but rather the prostate itself, so inflammation, infection or prostatic hypertrophy can all cause an increase in PSA.
The Korea Institute of Science and Technology has announced a new technique for diagnosing prostate cancer from the patient's urine, within 20 minutes with almost 100?curacy. The technique uses a urine-based ultrasensitive biosensor and AI analysis to risk stratify groups to look at cancer factors in the urine. The biosensor looked at four cancer factors in the urine that correlated with prostate cancer and trained the AI system to analyze the patterns of detected signals and attribute them to a prostate cancer diagnosis. The use of a single cancer factor led to a near 90?curacy in diagnosing prostate cancer. When multiple cancer factors were combined, this rose to near 100%.
