The Prostate What Every Man Over 40 Needs to Know About Prevention, Screening, and Common Problems

Let’s talk about something most men don’t want to discuss. It sits quietly in your body, doing its job, until one day—usually after 40—it starts making itself known. Suddenly you’re getting up three times a night to pee. Or the stream isn’t what it used to be. Or a routine blood test comes back with a number that sends you down an internet rabbit hole of worry.

The prostate. It’s small—about the size of a walnut—but it causes an outsized amount of anxiety, confusion, and downright avoidance.

Here’s what I’ve learned after talking to urologists, reading the research, and watching friends navigate prostate issues: The fear is often worse than the reality. And what you don’t know can actually hurt you.

Let’s demystify the prostate. What does it do? What goes wrong? How do you know if something’s wrong? And how do you navigate the confusing world of PSA testing and prostate cancer screening?

What Is the Prostate, Anyway?

The prostate is a gland located just below the bladder, in front of the rectum. It wraps around the urethra—the tube that carries urine and semen out of the body.

What it does:

• Produces prostatic fluid, which makes up about 30% of semen

• Helps propel semen during ejaculation

• Contains enzymes that help sperm remain viable

It’s a gland that grows throughout life. In young men, it’s about the size of a walnut. By age 40, it’s often the size of an apricot. By 60, it can be the size of a lemon.

This growth is normal. But when it grows too much, or grows in the wrong way, problems start.

The Three Main Prostate Problems

1. Benign Prostatic Hyperplasia (BPH)

BPH is non-cancerous enlargement of the prostate. It’s incredibly common—by age 60, about 50% of men have it. By age 85, about 90%.

What happens: The enlarged prostate squeezes the urethra, like stepping on a garden hose. This causes urinary symptoms.

Symptoms:

• Frequent urination, especially at night (nocturia)

• Urgency (feeling like you need to go now)

• Weak or intermittent stream

• Difficulty starting urination

• Dribbling at the end

• Feeling that your bladder isn’t empty

Is it dangerous? BPH itself is not cancer, and it doesn’t turn into cancer. But it can significantly affect quality of life. In severe cases, it can cause urinary retention (inability to pee), bladder stones, or kidney damage.

Treatment options:

• Watchful waiting: For mild symptoms, monitoring is reasonable.

• Lifestyle changes: Reducing evening fluids, avoiding caffeine and alcohol, double voiding (waiting and trying again).

• Medications: Alpha-blockers (tamsulosin/Flomax) relax prostate muscles. 5-alpha reductase inhibitors (finasteride) shrink the prostate over time.

• Minimally invasive procedures: UroLift, Rezum, and other office-based procedures open the urethra.

• Surgery: TURP (transurethral resection of the prostate) is the gold standard for severe cases.

2. Prostatitis

Prostatitis is inflammation of the prostate. It can be acute (sudden, severe) or chronic (long-term, often with less severe symptoms).

Acute bacterial prostatitis:

• Sudden onset of fever, chills, severe pelvic pain

• Painful, frequent urination

• Can’t urinate (retention)

• Requires immediate medical attention (IV antibiotics may be needed)

Chronic prostatitis/chronic pelvic pain syndrome:

• More common but less understood

• Persistent pelvic pain, discomfort with urination, pain with ejaculation

• May come and go over months or years

• No bacteria found, but symptoms are real

Treatment:

• Antibiotics (if bacterial)

• Anti-inflammatory medications

• Alpha-blockers

• Pelvic floor physical therapy (underrated and highly effective)

• Stress management, heat, sitz baths

3. Prostate Cancer

This is the one men fear most. And with good reason—prostate cancer is the second most common cancer in men (after skin cancer). About 1 in 8 men will be diagnosed in their lifetime.

Important truths:

• Not all prostate cancers are aggressive. Many grow so slowly they never cause problems. More men die with prostate cancer than from it.

• Early-stage prostate cancer often has no symptoms. That’s why screening is controversial—it finds cancers that may never need treatment.

• Treatment decisions are complex. What’s right for one man may be over-treatment for another.

Symptoms (when they appear):

• Similar to BPH (urinary symptoms)

• Blood in urine or semen

• Painful ejaculation

• Bone pain (if spread)

• Unexplained weight loss

Risk factors:

• Age (risk increases after 50)

• Family history (father or brother with prostate cancer doubles risk)

• Race (Black men have significantly higher risk)

• Genetics (BRCA mutations, Lynch syndrome)

• Diet (some evidence links high-fat diets, red meat)

The PSA Controversy: To Screen or Not to Screen?

PSA (prostate-specific antigen) is a protein produced by the prostate. A blood test measures PSA levels. Higher levels can indicate prostate cancer—but also BPH, prostatitis, infection, or even recent ejaculation.

The controversy: PSA screening can find cancers early, but it also finds many cancers that would never cause harm. This leads to over-diagnosis and over-treatment (biopsies, surgery, radiation) for cancers that would never have affected a man’s life.

Current guidelines vary:

What this means for you: There’s no single “right” answer. The decision to screen involves your values, your risk factors, and your willingness to accept the possibility of over-treatment.

If you screen:

• PSA should be drawn before any prostate manipulation (DRE, biopsy, ejaculation)

• Trend over time matters more than a single number

• Not every elevated PSA requires biopsy

• Risk calculators (like the one from the Prostate Cancer Prevention Trial) can help estimate your actual cancer risk

Understanding PSA Results

PSA is measured in ng/mL. General ranges:

Factors that affect PSA:

• Age: PSA naturally rises with age

• Prostate size: Larger prostates produce more PSA (even without cancer)

• Infection: Prostatitis can spike PSA

• Ejaculation: Can temporarily raise PSA (avoid 48 hours before test)

• Digital rectal exam (DRE): Can raise PSA (draw blood before DRE)

• Medications: Finasteride and dutasteride lower PSA by about 50%

Free PSA: If total PSA is elevated, measuring “free” (unbound) PSA can help. A lower percentage of free PSA (<10-15%) suggests higher cancer risk; higher free PSA (>25%) suggests BPH.

Lifestyle Factors for Prostate Health

While you can’t control your age or genetics, lifestyle matters.

Diet

• Tomatoes and lycopene: Cooked tomatoes (sauce, paste) are rich in lycopene, an antioxidant linked to lower prostate cancer risk.

• Cruciferous vegetables: Broccoli, cauliflower, cabbage, Brussels sprouts contain sulforaphane, which may have protective effects.

• Green tea: Contains catechins with anti-cancer properties.

• Fish and omega-3s: Fatty fish may reduce inflammation and cancer risk.

• Limit red meat and high-fat dairy: Some studies link high consumption to increased risk.

• Soy: Contains isoflavones that may be protective (moderate intake).

Exercise

Regular physical activity is linked to lower prostate cancer risk and better outcomes if diagnosed. Aim for 150+ minutes weekly of moderate activity.

Weight Management

Obesity is linked to more aggressive prostate cancer. Excess fat tissue promotes inflammation and hormonal changes that may fuel cancer growth.

Smoking

Smoking is linked to more aggressive prostate cancer and worse outcomes. Quitting matters.

Supplements (Use Caution)

• Vitamin E and selenium: Large trials showed no benefit and possibly increased risk with high-dose supplementation. Don’t take these for prostate prevention.

• Saw palmetto: Popular for BPH symptoms. Evidence is mixed; some studies show no benefit over placebo.

• Pomegranate, turmeric, etc.: Limited evidence; not harmful but not proven.

When to See a Urologist

Don’t ignore symptoms. See a provider if you experience:

• Difficulty starting urination

• Weak or interrupted stream

• Frequent urination (especially at night)

• Pain or burning with urination

• Blood in urine or semen

• Pain in lower back, hips, or pelvis

• Painful ejaculation

Also see a provider for routine discussions about screening starting at age 50 (or earlier if high-risk).

If You’re Diagnosed with Prostate Cancer

A diagnosis can be terrifying. But remember: prostate cancer is often slow-growing. You have time to make informed decisions.

Gleason score: This is how prostate cancer is graded. Scores range from 6 (low-grade, least aggressive) to 10 (high-grade, most aggressive). Low-grade cancers often warrant active surveillance (monitoring without immediate treatment).

Treatment options:

• Active surveillance: Monitoring with regular PSA, exams, and repeat biopsies. For low-risk cancer.

• Surgery (radical prostatectomy): Removal of the prostate. Can be robotic or open.

• Radiation therapy: External beam or brachytherapy (seeds).

• Hormone therapy (androgen deprivation therapy): Reduces testosterone (which fuels prostate cancer growth). Often used with radiation for higher-risk cancers.

• Focal therapy: Newer options like cryotherapy or high-intensity focused ultrasound (HIFU) treat only the cancer area, preserving the prostate.

Decision factors:

• Cancer grade and stage

• Your age and life expectancy

• Your values regarding side effects (erectile dysfunction, urinary incontinence)

• Overall health

This is not a decision to rush. Seek second opinions. Talk to men who have been through it. Work with a multidisciplinary team.

The Bottom Line

Your prostate is small but significant. It will change as you age. Most of those changes are not cancer, and most prostate cancers are not emergencies.

What matters:

• Know your family history

• Have open conversations with your provider

• Make informed decisions about screening that align with your values

• Don’t ignore symptoms

• If diagnosed, take time to understand your options

Prostate health is part of men’s health. And men’s health—physical, emotional, relational—deserves attention, not avoidance.
