Original source overview
What is cancer screening?Cancer is a disease when the cells of the body grow out of control. Cancer screening is having tests to look for signs of cancer before you have any symptoms. By the time cancer causes symptoms, it may have already spread to other parts of your body. A screening test may help find cancer early, when it may be easier to treat.
Cancer screening only tells you whether you might have cancer. It doesn't diagnose cancer. If a screening test shows signs of cancer, you'll need to have other tests to find out if you do have cancer and how serious it may be.
What is prostate cancer screening?Prostate cancer screening looks for signs of cancer in the prostate. The prostate is a gland in the male reproductive system. It lies just below the bladder. It makes fluid that is part of semen.
Prostate cancer is most common in people over age 50. It usually grows slowly and doesn't cause health problems. In fact, it's possible to live a long life with prostate cancer and never know you have it. But in certain cases, prostate cancer may spread to other parts of the body and can be very serious.
The goal of prostate cancer screening is to find prostate cancers that may be more likely to spread so they can be treated early.
What tests screen for prostate cancer?Two tests are commonly used to screen for prostate cancer:
• A prostate-specific antigen test, also called a PSA blood test. PSA is a protein made by your prostate. A high level of PSA in your blood may mean you have prostate cancer, but it's not proof of cancer. That's because many other things may cause high PSA levels, including:
• Having an enlarged prostate (benign prostatic hyperplasia or BPH) • Having other common prostate problems • Taking certain medicines
In general, the higher your PSA, the more likely it is that you have cancer. But a low PSA blood level isn't a guarantee that you don't have cancer.
• Digital Rectal Examination (DRE). The DRE is a prostate exam. In this exam, your health care provider inserts a lubricated, gloved finger into your rectum to feel your prostate for lumps or anything unusual. A DRE can check only one side of the prostate.
A PSA test or a DRE may be able to detect prostate cancer at an early stage. But it is not clear whether early detection and treatment lower the risk of dying from prostate cancer. You should talk with your provider about the benefits and harms of prostate cancer screening.
What are the possible benefits and harms of prostate cancer screening?The possible benefits of prostate cancer screening include:
• Finding and treating prostate cancer early before it spreads • Getting a better sense of your prostate cancer risk (based on your PSA test) • Peace of mind if your screening shows you're unlikely to have prostate cancer now • The option to choose further testing and closely monitor your prostate if your screening shows you may have cancer
The possible harms of prostate cancer screening include:
• Getting a false positive result. This means that your PSA test shows you may have prostate cancer when you really don't. A false positive may lead to:
• Worry while you have more tests to look for signs of cancer. • A prostate biopsy. In a biopsy, a doctor removes tissue from your prostate so it can be studied under a microscope to look for cancer cells. This is the only way to diagnose cancer. The possible harms of a prostate biopsy include:
• Fever • Pain • Blood in semen • Urinary tract infection
• Having prostate cancer treatment that you may not have needed. Prostate cancer screening may lead to a cancer diagnosis, but it's not always clear whether the cancer is likely to grow and spread. You could have unnecessary treatment for cancer that would never have caused any health problems. And the common prostate cancer treatments may have serious, permanent complications, such as:
• Urinary incontinence • Erectile dysfunction • Problems controlling your bowel movements (BMs)
Should I be screened for prostate cancer?Since there are benefits and risks to prostate screening, you should talk with your provider to decide if screening is right for you. You and your provider should consider:
• Your age. The risk of prostate cancer increases after age 50. • Your family health history. If members of your family have had prostate cancer, your risk may be higher. • Your race. Prostate cancer is more common in African Americans. They also have a higher risk of developing prostate cancer at a younger age and having more serious disease.
• Your general health. Are you well enough to have treatment for prostate cancer if it's found? • What you prefer. How do you feel about the possible benefits and harms of screening, diagnosis, and treatment?

Encyclopedic background — Wikipedia
The following selected excerpts provide background on “Prostate cancer screening”. The scope here is Prostate Cancer Screening; it does not establish an individual diagnosis or treatment plan. They are not a substitute for the source overview or current local clinical guidance. Each excerpt below comes from the fixed Wikipedia revision [W1].
Definition and overview [W1]
Prostate cancer screening is the screening process used to detect undiagnosed prostate cancer in men without signs or symptoms. When abnormal prostate tissue or cancer is found early, it may be easier to treat and cure, but it is unclear if early detection reduces mortality rates.
Screening precedes a diagnosis and subsequent treatment. The digital rectal examination (DRE) is one screening tool, during which the prostate is manually assessed through the wall of the rectum. The second screening tool is the measurement of prostate-specific antigen (PSA) in the blood. The evidence remains insufficient to determine whether screening with PSA or DRE reduces mortality from prostate cancer.
Most recent guidelines have recommended that the decision whether or not to screen should be based on shared decision-making, so that men are informed of the risks and benefits of screening. In 2012, the American Society of Clinical Oncology recommended screening be discouraged for those who are expected to live less than ten years, while for those with a longer life expectancy, a decision should be made by the person in question. In general, they concluded that based on recent research, "it is uncertain whether the benefits associated with PSA testing for prostate cancer screening are worth the harms associated with screening and subsequent unnecessary treatment."
Reading this topic in context
Use “Prostate Cancer Screening” as a starting point for a focused discussion, rather than treating every statement in the broader encyclopedia article as applying to you. The original source overview and the background excerpts answer different questions: the overview explains the health topic for readers, while the encyclopedia supplies terminology and general context. Keep a record of which questions concern symptoms, a confirmed diagnosis, prevention, or an existing treatment. This helps a healthcare professional address the relevant issue without relying on an internet label.
Questions to take to a professional
1. What are the potential benefits and harms of prostate screening for me?
2. What would happen after a raised test result or a decision not to screen?
Evidence, scope and next steps

Wikipedia [W1] is a secondary background source; its references can support further reading, but their presence is not evidence that WellPrimer has independently reviewed every study. No clinical review, guideline certification or NLM endorsement is claimed. For screening intervals, diagnostic thresholds, pregnancy or child-specific advice and treatment choices, check current guidance in your country with a qualified professional. Do not start, stop or change a prescribed medicine based on encyclopedia excerpts. New or worsening symptoms need appropriate clinical assessment rather than more reading alone.
