Key Takeaways
Prostate cancer is the second most common cancer in men, affecting 1 in 8 men during their lifetime
Early-stage prostate cancer often has no symptoms. Whether and when to have PSA screening should be decided with a healthcare professional after discussing your individual risk, preferences, and the potential benefits and harms.
Age, family history, and race are the strongest risk factors for developing prostate cancer
Most prostate cancers grow slowly and may not require immediate treatment
Five-year survival rates exceed 95% when caught early, emphasizing the importance of regular check-ups
Overview
Prostate cancer occurs when cells in the prostate gland grow out of control. The prostate is a walnut-sized gland that sits below the bladder and surrounds the urethra. It produces fluid that helps make semen.
This cancer affects millions of men worldwide. In the United States, hundreds of thousands of men are diagnosed each year, although the estimate changes from year to year. Most cases develop in men over 65, though it can occur in younger men too.
The good news is that many prostate cancers grow very slowly. Some men live their entire lives with prostate cancer without it ever causing serious problems. However, some types can be aggressive and spread quickly, which is why early detection and proper medical care are so important.
When prostate cancer is found before it has spread, outcomes are generally very favorable and several management options may be available, including active surveillance for some cancers. Regular check-ups with your doctor can help catch cancer before it becomes dangerous. Understanding your personal risk factors helps you decide when to start screening.
Symptoms & Signs
Early prostate cancer usually doesn't cause noticeable symptoms. Because early prostate cancer often causes no symptoms, men at risk should discuss the potential benefits and harms of PSA screening with a healthcare professional. When symptoms do appear, they often relate to urination or sexual function.
Possible Symptoms
Difficulty urinating - weak stream, trouble starting or stopping, or frequent urination especially at night
Blood in urine or semen - may appear pink, red, or brown in color
Painful urination or ejaculation - burning sensation or discomfort during these activities
Erectile dysfunction - difficulty getting or maintaining an erection, which can be related to various health conditions
Many men with these symptoms don't have cancer. Other conditions can cause the same problems, so it's important to see a doctor. Getting checked early can give you peace of mind or lead to early treatment.
When to Seek Care
Contact your doctor if you experience persistent urinary problems lasting more than a few weeks. Blood in urine or semen always requires medical evaluation. New erectile dysfunction or painful ejaculation should also prompt a medical visit.
If symptoms interfere with your daily life, don't wait to call your doctor. Keeping track of when symptoms started helps your doctor understand what's happening. It's better to get checked and find out everything is fine than to ignore warning signs.
When to Seek Immediate Care
Seek emergency care if you can't urinate at all, have severe pelvic pain, or notice large amounts of blood in your urine.
Causes & Risk Factors
Age
Risk increases dramatically after age 50, with most cases occurring after 65
Genetics
Having a father or brother with prostate cancer can increase your risk, especially if several close relatives were affected or a relative was diagnosed at a younger age.
Lifestyle
High-fat diet, obesity, and lack of exercise may increase risk
Other Conditions
Benign prostatic hyperplasia is not considered a cause of prostate cancer. Researchers continue to study how hormones and other biological factors affect prostate cancer risk.

Diagnosis
Medical History & Physical Examination
Your doctor will ask about your symptoms, family history, and overall health. They'll also perform a digital rectal exam (DRE), where they insert a gloved finger into the rectum to feel the prostate. This helps detect lumps, hard areas, or other abnormalities.
The doctor may also discuss your testosterone levels and other hormone-related factors that could affect prostate health. They'll want to know about any medications you take and lifestyle factors that might influence your risk.
Diagnostic Testing
PSA blood test - measures prostate-specific antigen levels, which may be elevated in cancer
Prostate biopsy - removes small tissue samples for microscopic examination to confirm cancer
Imaging tests may include MRI and, when appropriate, CT, bone, or other scans to assess the prostate and determine whether cancer has spread. The tests used depend on the person's risk and clinical findings.

Treatment Options
Treatment depends on the cancer's stage, your age, overall health, and personal preferences. Many early-stage cancers can be monitored rather than treated immediately.
Monitoring and Treatment Options
Active surveillance - regular monitoring with PSA tests and biopsies without immediate treatment
Hormone therapy - blocks testosterone to slow cancer growth, though this can affect testosterone levels significantly
Radiation therapy uses high-energy radiation to damage cancer cells while limiting exposure to nearby healthy tissue as much as possible.
Active surveillance is often used for slow-growing cancers that aren't causing problems. Your doctor monitors the cancer closely to see if it needs treatment later. This approach lets many men avoid surgery or radiation side effects.
Advanced Treatments
Surgery (prostatectomy) - removes the entire prostate gland when cancer is confined to the prostate
Chemotherapy - uses drugs to kill cancer cells when the disease has spread to other parts of the body
Immunotherapy - helps your immune system fight cancer cells more effectively
Your treatment team will discuss all available options with you. Each treatment has different benefits and possible side effects. Your personal goals and health status help determine the best treatment plan for you.
Living with the Condition
Daily Management Strategies
Stay active with regular exercise, which can help maintain energy and reduce treatment side effects. Eat a balanced diet rich in fruits and vegetables while limiting red meat and high-fat foods. Join support groups to connect with other men facing similar challenges. Keep a symptom diary to track changes and share with your medical team.
Managing side effects from treatment takes time and patience. Talk to your doctor about any problems you experience, as there are often solutions available. Many men find that other cancer survivors can offer helpful advice and encouragement.
Exercise & Movement
Gentle activities like walking, swimming, and stretching are usually safe during treatment. Avoid heavy lifting immediately after surgery or during active treatment. Some lifestyle factors that may affect recovery include substance use, so discuss these openly with your doctor.
Physical activity helps with both physical and mental health during cancer treatment. Moving your body regularly can reduce fatigue and improve mood. Your doctor can suggest safe exercises based on your treatment type and overall health.
Prevention
Maintain a healthy diet rich in fruits, vegetables, and whole grains while limiting red meat and high-fat dairy
Stay physically active for its many overall health benefits. Research has not clearly established that exercise prevents prostate cancer.
Consider regular screening starting at age 50, or earlier if you have risk factors
Discuss family history with your doctor to determine the best screening schedule for your situation
Tomatoes can be part of a balanced diet, but there is not enough evidence to say that tomatoes or lycopene prevent prostate cancer. Other foods like fatty fish and nuts contain nutrients that support prostate health. Making small dietary changes today can improve your long-term health.
Talking with your family about prostate cancer history is important. Knowing if relatives had prostate cancer helps you understand your own risk. Share this information with your doctor so they can recommend the right screening plan for you.
Frequently Asked Questions
While you can't completely prevent prostate cancer, healthy lifestyle choices may reduce your risk. A balanced diet, regular physical activity, and a healthy weight support overall health. It is not clear whether these changes prevent prostate cancer or slow its growth.
Many prostate cancer treatments can cause erectile dysfunction or other sexual problems. However, there are treatments available to help with these issues. Talk openly with your doctor about your concerns and available options.
PSA screening is an individual decision. Ask your healthcare professional when to discuss screening based on your age, health, family history, and other risk factors, and how often testing would be appropriate if you choose it. Your doctor can help determine the best schedule for your situation.
No, most men diagnosed with prostate cancer will not die from it. When caught early, the five-year survival rate is over 95%. Many prostate cancers grow so slowly they never cause serious health problems.
Some medications and substances may influence prostate health, though research is ongoing. It's important to discuss all medications and supplements with your doctor. They can help you understand any potential effects on your prostate health.
