Benign is a medical term that frequently arises in discussions about health, particularly when describing growths, tumors, or conditions. But What Does Benign Mean exactly? In simple terms, benign means not cancerous. When a condition is described as benign, it indicates that it is not malignant, does not spread to other parts of the body, and is generally not life-threatening. However, benign conditions can still cause discomfort, require treatment, and impact quality of life. A common example of a benign condition is benign prostatic hyperplasia (BPH), also known as an enlarged prostate.
Benign Prostatic Hyperplasia (BPH) Explained
Benign prostatic hyperplasia (BPH) is a condition characterized by the non-cancerous enlargement of the prostate gland. The prostate, a walnut-sized gland located below the bladder and in front of the rectum, surrounds the urethra, the tube that carries urine from the bladder out of the body.
The prostate gland typically undergoes two main phases of growth in a man’s life. The first phase occurs during puberty, when the prostate doubles in size. The second phase of growth begins around age 25 and continues throughout a man’s life. BPH is a common occurrence during this second growth phase, particularly in older men.

As the prostate enlarges in BPH, it can press on the urethra, narrowing it and obstructing the flow of urine. This constriction can lead to various urinary symptoms. While BPH is not cancer and does not increase the risk of prostate cancer, its symptoms can significantly affect a man’s daily life.
Other Names for Benign Prostatic Hyperplasia
Besides benign prostatic hyperplasia, this condition may also be referred to as:
- Enlarged prostate
- Benign prostatic hypertrophy
- Benign prostatic obstruction
These terms all describe the same underlying condition: a non-cancerous enlargement of the prostate gland.
How Common is Benign Prostatic Hyperplasia?
BPH is a very common condition, especially as men age. It is estimated that:
- 5% to 6% of men between 40 and 64 years old are affected by BPH.
- 29% to 33% of men aged 65 and older experience BPH.
In fact, BPH is the most prevalent prostate problem in men over the age of 50. It’s important to note that while BPH is common in older men, it rarely causes noticeable symptoms in men younger than 40.
Risk Factors for Benign Prostatic Hyperplasia
While the exact cause of BPH is not fully understood, several factors increase the likelihood of developing this condition. You are more likely to develop BPH if you:
- Are 40 years of age or older: Age is the most significant risk factor for BPH.
- Have a family history of BPH: Genetics can play a role, and having a family history increases your risk.
- Have certain health conditions: Conditions such as heart and blood vessel disease, type 2 diabetes, obesity, chronic kidney disease, and erectile dysfunction (ED) are associated with a higher risk of BPH.
- Lack physical activity: A sedentary lifestyle may increase the risk of BPH.
Complications of Untreated Benign Prostatic Hyperplasia
If left unmanaged, benign prostatic hyperplasia can lead to several complications. The primary issue stems from the enlarged prostate obstructing the urethra, making it difficult for the bladder to empty completely.
As the prostate grows and constricts the urethra, the bladder muscles must work harder to expel urine. Over time, this extra effort can weaken the bladder muscles, leading to incomplete bladder emptying and urinary retention, a condition where some urine remains in the bladder after urination.
Other potential complications of BPH include:
- Urinary tract infections (UTIs): Retained urine in the bladder can increase the risk of bacterial growth and UTIs.
- Bladder stones: Minerals in retained urine can crystallize and form bladder stones, causing irritation and further complications.
- Bladder damage: Chronic overfilling of the bladder due to urinary retention can stretch and weaken the bladder muscle over time.
- Kidney damage: In severe cases, pressure from urine backing up into the kidneys can lead to kidney damage.
Recognizing the Symptoms of Benign Prostatic Hyperplasia
The symptoms of BPH vary in severity among individuals, and not all men with an enlarged prostate will experience noticeable symptoms. However, common symptoms of BPH include:
- Difficulty starting urination: Hesitancy or trouble initiating the urine stream.
- Weak or interrupted urine stream: A urine stream that starts and stops, or is weaker than usual.
- Dribbling at the end of urination: Leakage of urine after urination has finished.
- Nocturia: Increased frequency of urination at night.
- Urinary urgency: A sudden, compelling need to urinate.
- Urinary frequency: Needing to urinate more often than usual during the day.
- Pain during urination: Although less common, some men may experience pain or discomfort while urinating.
It’s important to note that the severity of BPH symptoms doesn’t always correlate with the size of the prostate. Some men with significantly enlarged prostates may have mild symptoms, while others with only slightly enlarged prostates may experience more bothersome symptoms.
Certain medications, such as decongestants and antihistamines, can worsen BPH symptoms. It’s crucial to inform your healthcare provider about all medications you are taking.
If you experience any of these urinary symptoms, it’s essential to consult a healthcare professional. These symptoms can also be indicative of other urinary problems, such as bladder issues, urinary tract infections (UTIs), prostatitis (inflammation of the prostate), or even prostate cancer.
Seek immediate medical attention if you experience any of the following:
- Inability to urinate at all.
- Painful, frequent, and urgent urination accompanied by fever and chills.
- Blood in your urine.
- Severe discomfort or pain in your lower abdomen or urinary tract.

What Causes Benign Prostatic Hyperplasia?
The precise cause of benign prostatic hyperplasia remains unclear. However, researchers believe that age-related hormonal changes play a significant role in the development of BPH. As men age, the balance of hormones in their bodies shifts, which may stimulate prostate growth.
Diagnosing Benign Prostatic Hyperplasia
Diagnosing BPH typically involves a combination of:
- Personal and family medical history review: Your healthcare provider will ask about your symptoms, their duration and frequency, any history of UTIs, medications you are taking, fluid intake habits, and any significant medical history, including family history of prostate problems.
- Physical exam: This includes a digital rectal exam (DRE), where the healthcare provider inserts a gloved, lubricated finger into the rectum to feel the prostate gland and assess its size and condition. The physical exam may also include checking for an enlarged bladder and any discharge from the urethra.
- Medical tests: You may be referred to a urologist for further testing to confirm the diagnosis and rule out other conditions. These tests may include:
- Urinalysis: To check for infection or blood in the urine.
- Prostate-Specific Antigen (PSA) blood test: To screen for prostate cancer. Elevated PSA levels can indicate prostate enlargement, inflammation, or cancer, and further evaluation may be needed.
- Urine flow study (Uroflowmetry): To measure the rate and amount of urine flow, helping to assess the degree of urinary obstruction.
- Postvoid residual volume test: To measure the amount of urine remaining in the bladder after urination, indicating how well the bladder is emptying.
- Cystoscopy: A procedure where a thin, flexible tube with a camera is inserted into the urethra and bladder to visualize the urethra and bladder and rule out other conditions.
- Transrectal ultrasound: An ultrasound probe is inserted into the rectum to create images of the prostate, helping to assess its size and rule out prostate cancer.
Treatment Options for Benign Prostatic Hyperplasia
Treatment for BPH depends on the severity of your symptoms, their impact on your quality of life, and your overall health. Treatment options range from watchful waiting and lifestyle modifications to medications and surgical procedures.
Watchful Waiting and Lifestyle Changes
For men with mild BPH symptoms that do not significantly bother them, watchful waiting (also known as active surveillance) may be recommended. This approach involves regular checkups to monitor your symptoms without immediate active treatment.
Lifestyle modifications can also help manage mild BPH symptoms:
- Limit fluid intake, especially before going out or bedtime.
- Avoid or limit alcohol and caffeine consumption.
- Engage in regular physical activity.
- Practice double voiding: Trying to urinate a second time a few minutes after initially emptying your bladder.
- Urinate regularly and avoid holding urine for extended periods.
- Be mindful of medications that can worsen BPH symptoms, such as decongestants and antihistamines.
Medications for BPH
Several types of medications can help alleviate BPH symptoms by relaxing the muscles around the prostate and bladder neck or by reducing the size of the prostate. Common medications include:
- Alpha-blockers: These medications relax the muscles around the prostate and bladder neck, making it easier to urinate.
- 5-alpha reductase inhibitors (5-ARIs): These medications work by reducing the size of the prostate gland over time.
- Combination therapy: In some cases, a combination of an alpha-blocker and a 5-ARI may be more effective than either medication alone.
- Phosphodiesterase-5 inhibitors (PDE5Is): These medications, primarily used for erectile dysfunction, can also help relieve BPH symptoms in some men.
It’s important to discuss potential side effects of these medications with your healthcare provider.
Minimally Invasive Surgical Therapies (MIST)
For men with moderate to severe BPH symptoms who do not find sufficient relief from medications, minimally invasive surgical therapies (MIST) offer alternative treatment options. These procedures aim to remove excess prostate tissue or widen the urethra to improve urine flow. Examples of MIST procedures include:
- Transurethral resection of the prostate (TURP): A traditional procedure that involves removing prostate tissue using a wire loop inserted through the urethra.
- Transurethral water vapor therapy (Rezūm): Uses water vapor to heat and destroy excess prostate tissue.
- Prostatic urethral lift (UroLift): Implants are used to lift and hold the enlarged prostate tissue away from the urethra, widening the channel for urine flow.
Surgical Procedures for BPH
In cases of severe BPH with significant complications or when other treatments have failed, surgery to remove part or all of the prostate gland may be necessary. Surgical options include:
- Open prostatectomy: Surgical removal of the prostate gland through an incision in the lower abdomen.
- Laser prostatectomy: Uses laser energy to remove or destroy excess prostate tissue.
- Electrovaporization of the prostate (TUVP): Uses electrical energy to vaporize prostate tissue.
- Robotic-assisted prostatectomy: A minimally invasive approach using robotic technology to assist in prostate removal.
Post-Surgery Care and Potential Complications
Following prostate surgery, a Foley catheter is often inserted to drain urine from the bladder while the surgical area heals. This catheter is typically temporary, lasting for a few days.

Post-operative complications can occur and may include:
- Difficult or painful urination
- Temporary urinary incontinence, urgency, or frequency
- Blood or blood clots in the urine
- Infection
- Scar tissue formation
- Sexual problems, such as erectile dysfunction, retrograde ejaculation, and infertility.
It’s crucial to discuss potential risks and complications with your surgeon before undergoing any surgical procedure.
Problems related to BPH can sometimes recur after surgery, requiring further treatment. Regular follow-up appointments and prostate exams are essential to monitor for any recurrence.
Can Benign Prostatic Hyperplasia Be Prevented?
Currently, there is no known way to definitively prevent benign prostatic hyperplasia. However, maintaining a physically active lifestyle may help reduce your risk. If you have risk factors for BPH or are experiencing lower urinary tract symptoms, it’s important to discuss these concerns with your healthcare provider. Early diagnosis and treatment can help manage BPH and minimize its impact on your quality of life.
Diet and Lifestyle Considerations for BPH Management
While diet and nutrition are not considered direct causes or preventative measures for BPH, certain dietary and lifestyle adjustments can help manage symptoms.
- Limit fluid intake before outings and bedtime: This can reduce nighttime urination and urgency when away from home.
- Reduce or avoid alcohol and caffeine: These substances can irritate the bladder and worsen urinary symptoms.
- Maintain a healthy weight and diet: Obesity is a risk factor for BPH, and a balanced diet can contribute to overall health.
Clinical Trials and BPH Research
Ongoing clinical trials are crucial for advancing our understanding and treatment of benign prostatic hyperplasia. Researchers are actively investigating various aspects of BPH, including the underlying causes of prostate enlargement and improvements in medications and surgical techniques. Participating in clinical trials can contribute to medical progress and potentially benefit future generations of men with BPH.
To find out more about BPH clinical trials, you can visit ClinicalTrials.gov for a list of federally funded, open, and recruiting studies. Always consult with your healthcare provider before participating in any clinical trial.
In conclusion, understanding what does benign mean is crucial when discussing medical conditions. Benign prostatic hyperplasia, while not cancerous, is a common condition that can significantly impact men’s health and quality of life. By understanding the symptoms, risk factors, and available treatments, men can proactively manage BPH and maintain their well-being. If you are experiencing urinary symptoms, seeking medical advice is the first step towards diagnosis and effective management.
