Two very different conditions can cause similar urinary symptoms. Here's how to tell them apart, and when to see a doctor.
Benign prostatic hyperplasia (BPH) — a non-cancerous enlargement of the prostate — and prostate cancer can both press on or affect the urethra as the prostate changes size or shape. That's why symptoms like a weaker urine stream, more frequent urination, or getting up multiple times at night can show up with either condition, along with plenty of other, more common causes.
Because the two conditions can overlap, these symptoms alone don't tell you which one (if either) you're dealing with:
Most men who experience these symptoms have BPH, not cancer — BPH becomes increasingly common with age and is far more prevalent than prostate cancer at any given age. But because the symptoms overlap, symptoms alone can't rule cancer out either.
Some symptoms are less typical of ordinary age-related BPH and warrant a doctor's visit sooner rather than later:
None of these symptoms mean you definitely have prostate cancer — many have other explanations — but they're the ones doctors specifically watch for, and they deserve a prompt evaluation rather than a wait-and-see approach.
A doctor typically starts with a PSA (prostate-specific antigen) blood test and a digital rectal exam, then follows up with imaging or a biopsy if something looks unusual. Neither BPH nor prostate cancer can be reliably diagnosed from symptoms alone — testing is what actually distinguishes them.
Age-related urinary changes are extremely common, and most of the time they point to ordinary BPH rather than something more serious. Still, because the two conditions can look similar early on, any new or worsening urinary symptoms — especially blood in the urine, unexplained pain, or weight loss — are worth bringing to a doctor. Routine prostate checkups become more important as men move through their 50s and beyond, and catching any issue early gives you far more options.
