Understanding Benign Prostatic Hyperplasia (BPH)
Benign prostatic hyperplasia (BPH) is the non-cancerous enlargement of the prostate gland. The prostate is a small gland located below the bladder that surrounds the urethra, the tube through which urine and semen pass. As the prostate enlarges, it can press on the urethra, obstructing the flow of urine.
While BPH is an extremely common condition in aging men, the idea that every man in his 70s has it is not accurate. The prevalence rate rises significantly with age, affecting about 50% of men between 51 and 60, and climbing to around 80% for men over 70. Importantly, not all men who have BPH will experience bothersome symptoms. Some may have only mild urinary issues or none at all.
The Role of Age and Other Risk Factors
The exact cause of BPH is unknown, but it is strongly linked to aging and hormonal changes. As men get older, levels of testosterone decline while estrogen levels can remain constant or increase slightly. This hormonal imbalance may stimulate the growth of prostate cells. Another hormone, dihydrotestosterone (DHT), is also thought to play a key role in prostate enlargement.
Beyond age, several other risk factors increase the likelihood of developing BPH:
- Family History: Having a blood relative, such as a father or brother, with BPH increases your risk.
- Obesity and Diabetes: Medical conditions like type 2 diabetes and heart disease have been linked to a higher risk of BPH. Obesity, particularly abdominal fat, is also a significant risk factor.
- Sedentary Lifestyle: A lack of physical activity can increase the risk of BPH.
- Ethnicity: Some studies suggest that African American and Caucasian men are more at risk for BPH than Asian men.
Symptoms of an Enlarged Prostate
An enlarged prostate's symptoms, known as Lower Urinary Tract Symptoms (LUTS), can vary in severity and may not always correlate with the size of the prostate. Common signs include:
- Frequent or urgent need to urinate: Needing to urinate more often than usual, especially at night (nocturia).
- Weak or slow urine stream: The stream may be weak, stop and start, or have dribbling at the end.
- Difficulty starting urination: Urinary hesitancy can make it hard to begin the flow of urine.
- Incomplete bladder emptying: The feeling that the bladder is never completely empty, even after urinating.
- Urinary tract infections (UTIs): The inability to empty the bladder completely can increase the risk of infection.
BPH vs. Prostate Cancer: A Crucial Comparison
Many men confuse BPH with prostate cancer because they share some similar symptoms. It is vital to understand that BPH is not cancerous and does not increase the risk of developing prostate cancer. However, a man can have both conditions at the same time. A doctor can perform diagnostic tests to determine the correct diagnosis.
| Feature | Benign Prostatic Hyperplasia (BPH) | Prostate Cancer |
|---|---|---|
| Nature | Non-cancerous (benign) tissue overgrowth | Malignant (cancerous) cell growth |
| Location of Growth | Typically in the transitional zone surrounding the urethra | Can develop anywhere in the prostate, often in the outer glandular area |
| Effect | Compresses the urethra, obstructing urine flow | May or may not cause obstruction; symptoms often appear in later stages |
| Symptoms | Lower urinary tract symptoms (weak stream, frequency, urgency) | May have no symptoms initially; advanced stages can cause pain in back/hips, urinary issues, or blood in urine/semen |
| Diagnosis | Based on medical history, physical exam (DRE), urine tests, and sometimes PSA tests | Confirmed with a prostate biopsy to examine prostate tissue for cancer cells |
Diagnosing and Treating BPH
If you experience urinary symptoms, it is important to see a healthcare provider for a proper diagnosis. Diagnosis may involve a physical exam, including a digital rectal exam (DRE), urine and blood tests, and sometimes an ultrasound or other imaging.
Treatment options depend on the severity of symptoms and the individual's overall health:
- Watchful Waiting: For mild symptoms, a doctor may recommend monitoring without immediate treatment. This can be combined with lifestyle adjustments, such as reducing fluid intake before bed or limiting caffeine and alcohol.
- Medication: A variety of drugs are available to manage BPH symptoms. Alpha-blockers relax the muscles in the prostate and bladder neck, improving urine flow. 5-alpha reductase inhibitors can shrink the prostate by suppressing hormones. Combination therapies may also be used for more effective relief.
- Minimally Invasive Procedures: For moderate to severe symptoms that don't respond to medication, procedures like transurethral water vapor therapy (Rezum) or prostatic urethral lift (UroLift) are options. These methods remove or lift prostate tissue to open the urethra.
- Surgery: In severe cases, surgical options like Transurethral Resection of the Prostate (TURP) or laser surgery can remove obstructing prostate tissue.

Conclusion
While an enlarged prostate is a highly prevalent condition among men over 70, it is not an inevitable fate for all. The statistics show a high likelihood, but individual experiences with BPH and its symptoms can differ widely. A proactive approach to prostate health, including regular checkups and discussing any urinary symptoms with a healthcare provider, is crucial. For those who do experience symptoms, numerous effective treatments are available to manage the condition and maintain a good quality of life.
