Benign Prostatic Hyperplasia: Recognizing Symptoms and the Link to Prostate Cancer

Benign Prostatic Hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland that compresses the urethra, leading to urinary dysfunction.

What are the primary symptoms of BPH?

BPH causes lower urinary tract symptoms (LUTS) because the growing prostate gland squeezes the tube that carries urine out of the bladder.

• Weak urinary stream: The flow of urine is slower or stops and starts.
• Nocturia: A frequent need to urinate during the night, disrupting sleep.
• Urgency: A sudden, strong need to urinate that is difficult to delay.
• Hesitancy: Difficulty starting the flow of urine.
• Residual urine: The sensation that the bladder isn’t completely empty after voiding.

How does BPH differ from prostate cancer?

BPH and prostate cancer are distinct conditions, though they can occur simultaneously. BPH involves the growth of the inner transition zone of the prostate, while prostate cancer typically develops in the outer peripheral zone. According to Harvard Health Publishing, BPH doesn’t increase the risk of developing prostate cancer, but the two conditions often share similar symptoms.

The primary difference lies in the nature of the cells. BPH is benign, meaning it doesn’t spread to other parts of the body. Prostate cancer is malignant and can metastasize. Because both conditions compress the urethra, a man experiencing a weak stream can’t determine the cause based on symptoms alone. This overlap makes clinical screening essential for men over 50, or earlier for those with a family history.

How is prostate health diagnosed?

Doctors use a combination of tests to distinguish between BPH and malignancy.

• Digital Rectal Exam (DRE): A physician inserts a gloved finger into the rectum to feel the prostate’s size, shape, and texture. Hard lumps or irregularities may suggest cancer, while a smooth, enlarged gland typically suggests BPH.
• Prostate-Specific Antigen (PSA) Test: This blood test measures the level of PSA, a protein produced by the prostate.

If results are inconclusive, doctors may use transrectal ultrasound (TRUS) or a prostate biopsy to confirm the presence of cancerous cells.

What are the treatment options for an enlarged prostate?

Treatment depends on the severity of the symptoms and the impact on the patient's quality of life.

Lifestyle Adjustments

For mild symptoms, doctors suggest limiting fluids before bedtime, reducing caffeine and alcohol intake, and avoiding certain decongestants that can tighten the bladder neck.

Medications

Alpha-blockers, such as tamsulosin, relax the muscles in the prostate and bladder neck to make urination easier. 5-alpha reductase inhibitors, like finasteride, actually shrink the prostate gland by blocking hormones that fuel its growth.

Surgical Interventions

When medication fails, surgical options are used to remove the obstructing prostate tissue. The most common procedure is the Transurethral Prostate Resection (TURP), where a surgeon removes pieces of the prostate through the urethra. Newer, minimally invasive options include laser therapy and UroLift, which uses implants to hold the prostate tissue away from the urethra.

Frequently Asked Questions

Can BPH turn into prostate cancer?
No. BPH is a benign growth. According to Harvard Health, there is no evidence that BPH causes cancer, though both may be present at the same time.

At what age should men start screening for BPH and cancer? Men with a first-degree relative who had prostate cancer or African American men should start the conversation at age 45.

Is a high PSA level always a sign of cancer?
No. PSA levels can rise due to BPH, inflammation (prostatitis), or recent physical activity. A high PSA is a signal for further investigation, not a definitive diagnosis of cancer.

Urinary symptoms such as a weak urine stream, feeling of incomplete emptying, or nighttime urination are representative symptoms of BPH. Ignoring these symptoms can lead to the discovery of prostate cancer.
