Key fact

Prostate cancer is the most common cancer among men in the United States.

The short answer

Prostate cancer is the most common cancer among men in the United States and the second leading cause of cancer death among men. It usually grows very slowly. Because of this, finding and treating it early does not always help a man live longer or feel better.

  • Prostate cancer is the most common cancer among men in the United States.

  • It is the second leading cause of cancer death among men in the United States.

  • Prostate cancer usually grows very slowly.

  • Finding and treating it before symptoms appear may not always improve health or help a man live longer.

Subjective: What you might experience

This section describes the symptoms and history a patient might report to their doctor.

Often no symptoms early

frequently found through PSA testing.

Urinary changes

weak or interrupted stream, frequent urination (especially at night), trouble starting.

Blood in the urine or semen.

Erectile difficulty.

In advanced disease

pain in the hips, back, or chest from bone spread.

Risk history

age, family history, African ancestry, and inherited gene changes.

Objective: Tests and findings

PSA (prostate-specific antigen) blood test and digital rectal exam.

Prostate MRI to identify suspicious areas.

Prostate biopsy for tissue diagnosis and Gleason grading

the definitive test.

Imaging (bone scan, CT, or PSMA PET) if spread is suspected.

Repeat PSA trends over time.

Assessment: Staging and prognosis

Diagnosis confirmed by biopsy; graded with the Gleason score / Grade Group.

Staged with the TNM system and combined with PSA and grade into risk groups.

Risk category (low, intermediate, high) drives whether active surveillance or treatment is advised.

Many prostate cancers are slow-growing and may not need immediate treatment.

Plan: The treatment approach

Active surveillance for low-risk disease, with regular PSA, exams, and repeat biopsy/MRI.

Surgery (prostatectomy) or radiation therapy for localized disease needing treatment.

Hormone therapy, often with radiation, for higher-risk or advanced disease.

Advanced/metastatic

hormone therapy, chemotherapy, targeted therapy, and clinical trials.

Monitoring PSA and managing treatment side effects.

Common questions

Is prostate cancer common?

Yes. Prostate cancer is the most common cancer among men in the United States. It is also the second leading cause of cancer death among men in the country.

Does prostate cancer grow slowly?

Usually, yes. Prostate cancer typically grows very slowly. Because it often grows so slowly, finding and treating it before symptoms appear may not always improve a man's health or help him live longer.

Is there a screening test for prostate cancer?

A test called the prostate-specific antigen (PSA) test is one tool related to prostate cancer screening. Your healthcare team can explain what screening options may make sense for you.

Does finding prostate cancer early always help?

Not always. Because prostate cancer usually grows very slowly, finding and treating it before symptoms occur may not improve a man's health or help him live longer. This is something to discuss with a healthcare team.

How this page was created

Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.

Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.

General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.

Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
