The most common cancer in men. Often slow-growing; many cases never require treatment. Lifestyle factors, lycopene from tomatoes, omega-3, low animal fat, sufficient vitamin D, and aerobic exercise, significantly modify progression risk.

Prostate cancer arises from cells of the prostate gland, a walnut-sized organ below the bladder that produces seminal fluid. Most prostate cancers are adenocarcinomas. The disease is exceptionally heterogeneous, ranging from indolent tumors that never threaten life to aggressive cancers that rapidly metastasize.
Risk is influenced by age (rare under 50, common over 65), genetics (BRCA2, HOXB13, Lynch syndrome), race (highest in African American men), and lifestyle. The disease's androgen dependence drives both conventional treatment (androgen deprivation) and lifestyle approaches (managing IGF-1, insulin, inflammation).
The challenge is distinguishing "tigers" from "pussycats." Low-risk disease (Gleason โค6, PSA <10) often doesn't need immediate treatment, Active Surveillance with close monitoring spares men the side effects of overtreatment while preserving the option to treat if progression occurs.
PSA <10, Gleason 6 (Grade Group 1), T1c-T2a. Active Surveillance preferred. Decades of life expectancy. Many never need treatment.
PSA >20, Gleason 8-10, or extracapsular extension. Aggressive treatment: surgery or radiation + ADT. Metastatic disease: ADT + chemo or newer agents.
Most early prostate cancers are asymptomatic, found only by PSA screening or incidentally. Urinary symptoms usually indicate advanced disease OR more commonly benign prostatic hyperplasia (BPH).
Weak or interrupted urine stream, straining to urinate, sense of incomplete emptying. Usually from BPH but warrants prostate evaluation.
Nocturia 2+ times nightly. Urgency. Frequent small voids during day. Most often BPH but evaluate.
Hematuria or hematospermia. Always warrants evaluation. May indicate advanced prostate cancer, but more often other urologic causes.
May indicate prostatitis (more common), urethral involvement, or advanced cancer. Evaluation needed.
Persistent deep aching pain. Bone is the most common metastatic site. Spine metastases can cause cord compression, emergency.
Spinal cord compression, EMERGENCY. New-onset back pain with neurologic symptoms requires immediate evaluation. Permanent paralysis possible if delayed.
Constitutional symptoms of advanced disease. Anemia common from bone marrow involvement.
May indicate advanced local disease. More commonly age-related or due to other causes. Combination with urinary symptoms warrants prostate evaluation.
Blood test. Not cancer-specific (BPH, prostatitis also raise). PSA velocity (rise over time) and density (PSA/prostate volume) more informative than single values.
Palpates posterior prostate for nodules, asymmetry, induration. Insensitive (misses many tumors) but specific when abnormal. Adjunct to PSA.
3T MRI with PI-RADS scoring before biopsy. Reduces unnecessary biopsies and detects clinically significant cancers. Increasingly standard practice.
Image-guided sampling of MRI-detected lesions plus systematic cores. More accurate than systematic biopsy alone. Reports Gleason score, percent involvement.
Particularly relevant for Active Surveillance, prevention, and survivorship. Ornish lifestyle trial showed disease regression in early-stage.
Mediterranean + lycopene + cruciferous + plant-forward. Reduces risk of aggressive disease and slows progression.
Tomato sauce, paste, cooked tomatoes (10+ servings/week). Cooking + olive oil increase lycopene bioavailability 4x. 30% reduction in aggressive prostate cancer.
Broccoli, broccoli sprouts (especially), cauliflower, kale, cabbage. Sulforaphane has direct anti-prostate cancer activity.
EGCG slows progression in early studies. May reduce risk of high-grade disease. Most effective when consumed regularly long-term.
Wild salmon, sardines, mackerel. Omega-3 anti-inflammatory. Avoid charred grilling.
Slows PSA doubling time in recurrent disease. Antioxidant and anti-androgen effects in lab studies.
Strongest dietary risk factor. Especially well-done, grilled, or charred meats (HCAs, PAHs). Limit red meat <3 servings/week; eliminate processed.
Total calcium >1,500mg/day associated with aggressive disease. Don't exceed dairy 1-2 servings/day. Avoid high-dose calcium supplements.
Pro-inflammatory. Associated with aggressive prostate cancer. Eliminate fast food, commercial baked goods, hydrogenated oils.
Drive insulin and IGF-1, growth factors for prostate cancer. White bread, sodas, sweets, juices.
>2 drinks/day increases risk and may worsen prognosis. Heavy or binge drinking particularly harmful.
Best evidence: vitamin D, omega-3 (cautiously), lycopene, pomegranate, sulforaphane. ALWAYS discuss with urology/oncology team.
| Supplement | Mechanism & Evidence | Suggested Dose | Timing | Notes |
|---|---|---|---|---|
| Vitamin D3 | Deficiency associated with aggressive disease and worse mortality. Anti-proliferative in lab studies. | 2,000-5,000 IU/day (titrate to 50-80 ng/mL) | With fat meal | Test baseline. Pair with K2 200mcg. |
| Lycopene | Carotenoid concentrating in prostate. Food sources (cooked tomato) likely better than isolated supplements. | 15-30mg/day from supplement OR daily cooked tomatoes | With fat meal | Synergy with cooking and olive oil. |
| Pomegranate Extract | Slows PSA doubling time. Anti-androgen effects in lab. Multiple bioactive compounds. | 8 oz juice/day OR 250-500mg extract | With food | Real fruit/juice preferred over extract. |
| Sulforaphane (or Broccoli Sprouts) | Activates Nrf2 antioxidant pathway. Modulates androgen receptor. Best from fresh broccoli sprouts. | 20-100mg sulforaphane/day OR 2-4 oz fresh broccoli sprouts | Empty stomach | Sprouts have ~100x sulforaphane of mature broccoli. Activate with chewing or chopping. |
| Omega-3 (EPA/DHA) | Anti-inflammatory. Mixed evidence in prostate cancer (some studies show increased risk at very high doses), moderate from food preferred. | 1,000-2,000mg EPA+DHA/day from supplement OR fatty fish | With fat meal | Food-based preferred. Discuss high-dose supplements with oncologist. |
| Green Tea Extract (EGCG) | Multiple anti-cancer mechanisms. Best evidence for prevention/early disease. | 500-1,000mg EGCG/day | Empty stomach | Liver toxicity rare at high doses. Discontinue if liver enzymes elevate. |
| Selenium | SELECT trial showed no benefit and possible harm from synthetic selenomethionine. Brazil nuts safer. | 1-2 Brazil nuts/day (food source) | With food | DO NOT take selenium supplements based on current evidence, possible harm. |
| Modified Citrus Pectin | Binds galectin-3 (involved in metastasis). Small studies show PSA modulation. | 5g 3x/day | Empty stomach | Limited evidence but generally safe. Considered for advanced disease. |
Many prostate cancers don't need aggressive treatment. Work with a urologist who supports Active Surveillance for appropriate cases, avoiding overtreatment matters as much as treating aggressive disease. Lifestyle changes (especially Ornish-style intervention) can be powerful for low-risk disease and survivorship.
