A new retrospective cohort study claims that men with low testosterone levels may face a greater risk of developing higher-grade disease; the data came from undergoing active surveillance (AS) for localised prostate cancer. The study evaluated 924 men who participated in AS between 2005 and 2024 to find out if lower serum testosterone levels are connected with Grade Group (GG) progression.The participants in this study had an average age of 63.6 years, with a mean baseline testosterone level of 394 ng/dL. About 29% of the patients at the AS had testosterone levels at ≤300 ng/dL, which was a benchmark to define low testosterone. The study finds that having lower testosterone may lead to progression to GG2 disease and faster progression to GG3 or higher. The researchers found at the AS that men with testosterone levels ≤300 ng/dL had a 61% higher risk of higher progression than men with high testosterone levels.What Is Prostate Cancer?The gland in the male reproductive system that makes seminal fluid is the prostate. This is the most common type of slow-growing cancer in men, which sees the abnormal growth of cells in the gland; if detected early, it is very much curable. Some early-stage symptoms of the disease are blood in the urine or semen, trouble urinating, and erectile dysfunction, and if you’re asking yourself, why you?You could probably blame age, family history, or lifestyle choices. While we cannot change the ‘why’, we can master the ‘how’ of finding the right treatment in time. Step 1: Rule out the possibility of cancer with a simple Prostate-Specific Antigen (PSA) blood test.In the last 10 years, technology and innovation have revolutionized the diagnostics and treatments of the disease. Scientists from across the world are working around the clock, making marked improvements in treating prostate cancer.
