Which statement about benign prostatic hypertrophy is incorrect?

The statement regarding saw palmetto being "always effective in reducing symptoms" is indeed incorrect. While saw palmetto is often used by many men seeking relief from the symptoms associated with benign prostatic hypertrophy (BPH), clinical studies have shown mixed results regarding its efficacy. Some studies suggest that it may provide some benefit for symptom relief, while others demonstrate minimal to no significant effect when compared to a placebo. Therefore, it cannot be deemed "always effective," as individual responses to herbal supplements can vary widely.

In contrast, the other statements regarding BPH are accurate. The prevalence of BPH increases with age, affecting up to 50% of men older than 50. Common symptoms include dribbling and nocturia, which can significantly impact a man’s quality of life due to the frequent need to urinate at night. Additionally, a slightly elevated prostate-specific antigen (PSA) level is often observed in men with BPH. However, this elevation is generally not indicative of prostate cancer, but rather can be attributed to the benign enlargement of the prostate tissue.
