 Hello, I'm Dr. John Feller, I'm the Chief Medical Officer for Halo Diagnostics, and I'd like to talk with patients out there, men in particular, about using a screening PSA to detect prostate cancer. Turns out the screening PSA is a very, very good screening test for early detection of prostate cancer and can help to reduce the mortality or death rate from prostate cancer by more than 25%. In recent years, there had been a decreased interest in getting the screening serum PSA because it was also shown that this test could result in over diagnosis and over treatment of prostate cancer that was clinically insignificant and didn't need to be treated. Well, that problem has been addressed by adding a new type of MRI to the screening process called a multi-parametric MRI of the prostate. Some people call this a manogram, kind of like the mammogram that a woman gets. Turns out if the PSA is elevated, then you can go on to do an MRI of the prostate. If that MRI shows a suspicious area, which happens in about two-thirds of the cases, then the patient goes on to get an MRI targeted by Opsi of the prostate to detect whether or not there's prostate cancer there. If the MRI is negative, which happens in about a third of the cases or more, then the patient doesn't need to undergo any type of a biopsy.
