Understanding of PSA biology, factors affecting PSA detection, challenges, various biomarkers, methods, and future perspective of prostate cancer detection and diagnosis

Cancer is a global challenge for healthcare professional due to multiple unresolved issues before therapy, during therapy, and post-therapy stages. The disease diagnosis and subsequent chemotherapy are an ideal treatment approach to culminate such menace. Among cancers, prostate cancer (PC) is considered next to skin and breast cancer as the most dreadful and recorded with high mortality. It is also one of the leading causes of cancer death among men. With increased incidence worldwide and high mortality rate prostate cancer remains a global healthcare challenge. Advances in the diagnosis of PC have improved the chances of patient survival. Today, scientists developed electrochemical biosensors for early diagnosis of PC and it was found to be playing a significant role to reduce cases, mortality and complication at clinical set up. This updated review focused on biomarkers and traditional techniques used for PC diagnosis (early) and the most recent achievements of electrochemical techniques for making successful translation to clinical bed. Nanoparticles based electro-biochemical techniques have gained considerable attention alternative to traditional techniques. These techniques are found significantly effective for PC detection and have shown interesting parameters such as low cost and easy incorporation to user-friendly sensing platforms. With further advancements portable devices can be developed that can diagnose PC earlier for rapid clinical analysis and subsequently earliest report availability to the physician office for quick decision and life-saving approach. Overall, these compiled data in a form of review paper supports the adoption and promotion of nanotechnology-based diagnostics for PC in the healthcare.
