Active Surveillance of Low-Risk Prostate Cancer
What is Active Surveillance of Low-Risk Prostate Cancer?
Active surveillance is a way to monitor low-risk prostate cancer without immediate treatment. This approach uses regular blood tests, physical exams, and sometimes biopsies to track whether the cancer is growing or changing. Many prostate cancers grow very slowly and may never cause harm during a man's lifetime.
Instead of rushing into surgery or radiation, active surveillance lets you watch and wait. Your doctor checks specific biomarkers like PSA every few months to spot any signs of progression. This strategy helps you avoid treatment side effects while staying safe. If tests show the cancer is growing more aggressively, you can switch to active treatment at any time.
Active surveillance works best for men with low-grade, localized prostate cancer. That means the cancer is small, slow-growing, and has not spread beyond the prostate gland. Your doctor uses a Gleason score to grade the cancer cells. Scores of 6 or low 7 typically qualify for surveillance. This approach gives you time to live your life while keeping a close eye on your health.
Symptoms
- No new symptoms in most cases, since the cancer is low-grade
- Difficulty starting or stopping urination
- Weak or interrupted urine flow
- Frequent urination, especially at night
- Pain or burning during urination
- Blood in urine or semen
- Pain in the lower back, hips, or pelvis
- Painful ejaculation
Most men on active surveillance feel completely healthy. The cancer is usually found through routine PSA screening, not because of symptoms. Any new or worsening symptoms should be reported to your doctor right away, as they may signal disease progression.

Causes and risk factors
Prostate cancer develops when cells in the prostate gland begin to grow abnormally. Age is the biggest risk factor, with most cases occurring in men over 65. Family history matters too. Men with a father or brother who had prostate cancer face two to three times higher risk. African American men have the highest rates of prostate cancer and tend to develop more aggressive forms at younger ages.
Lifestyle factors may influence prostate cancer risk and progression. Diets high in red meat and high-fat dairy products are linked to increased risk. Obesity and lack of physical activity may also play a role. Some research suggests that inflammation in the body can fuel cancer growth over time. While you cannot change your age or genetics, you can focus on healthy habits to support your overall prostate health during active surveillance.
How it's diagnosed
Active surveillance begins after a prostate cancer diagnosis through biopsy. Your doctor uses several tools to confirm the cancer is low-risk enough for monitoring. The Gleason score grades how abnormal the cancer cells look. The PSA level measures prostate-specific antigen in your blood. A digital rectal exam checks the size and texture of your prostate. Imaging tests like MRI may show where the cancer is located and how much of the gland is affected.
Once you start active surveillance, regular PSA testing becomes essential. Most protocols call for PSA checks every 3 to 6 months. The Free PSA ratio test helps refine your risk assessment. A declining free PSA percentage over time may indicate your cancer is becoming more aggressive. Rising total PSA levels can also signal progression. Rite Aid offers PSA testing as an add-on to our blood panel at Quest Diagnostics locations nationwide. Tracking your PSA trends helps you and your doctor decide if you need to switch from surveillance to treatment.
Treatment options
- Regular PSA blood tests every 3 to 6 months to monitor trends
- Digital rectal exams one to two times per year
- Repeat prostate biopsies every 1 to 3 years to check cancer grade
- Prostate MRI scans to watch for tumor growth
- Heart-healthy diet rich in vegetables, fruits, and omega-3 fatty acids
- Regular physical activity to maintain healthy weight and reduce inflammation
- Limiting red meat, processed foods, and high-fat dairy products
- Stress management through meditation, yoga, or counseling
- Transition to active treatment if tests show cancer progression
- Treatment options include surgery, radiation, or hormone therapy if needed

Frequently asked questions
Active surveillance is a monitoring strategy for low-risk prostate cancer that avoids immediate treatment. You get regular blood tests, physical exams, and biopsies to watch for signs of cancer progression. If tests show the cancer is growing more aggressively, you can switch to treatment at any time. This approach helps men avoid surgery or radiation side effects while staying safe.
Men with low-grade, localized prostate cancer are best suited for active surveillance. This typically means a Gleason score of 6 or low 7, small tumor size, and cancer confined to the prostate gland. Your PSA level should be relatively low, usually under 10 to 20. Your doctor will review your biopsy results, imaging scans, and overall health to determine if surveillance is right for you.
Most active surveillance protocols recommend PSA testing every 3 to 6 months. Your doctor will track trends in both total PSA and free PSA ratio over time. Rising PSA levels or declining free PSA percentage may signal disease progression. Regular monitoring helps catch any changes early so you can make informed decisions about moving to treatment.
The free PSA ratio compares the amount of free PSA to total PSA in your blood. A declining ratio over time may indicate your prostate cancer is becoming more aggressive. Men on active surveillance use this test to refine their risk assessment beyond total PSA alone. Your doctor will look at trends across multiple tests rather than focusing on a single result.
You should consider treatment if your PSA levels rise significantly, your free PSA ratio declines, or repeat biopsies show higher-grade cancer. New symptoms like bone pain or difficulty urinating may also signal progression. Your doctor will review all your test results and imaging scans to help you decide the right time to act. The goal is to intervene before the cancer has a chance to spread.
Research suggests that healthy lifestyle habits may slow cancer growth during active surveillance. A diet rich in vegetables, fruits, and omega-3 fatty acids from fish supports prostate health. Regular exercise helps maintain a healthy weight and reduces inflammation in the body. Limiting red meat, processed foods, and saturated fats may also help. While lifestyle changes cannot cure cancer, they can support your overall health during monitoring.
Studies show that active surveillance is safe for carefully selected men with low-risk prostate cancer. The key is close monitoring with regular PSA tests, exams, and biopsies. Most low-grade prostate cancers grow very slowly and are unlikely to spread during surveillance. If tests detect progression, switching to treatment at that point still leads to excellent outcomes in most cases.
A prostate biopsy involves taking small tissue samples from your prostate gland using a thin needle. The procedure is usually done through the rectum and guided by ultrasound. Most men have biopsies done in a doctor's office with local anesthesia. You may feel some pressure or discomfort, and minor bleeding in urine or semen is common for a few days afterward.
Many men remain on active surveillance for years or even decades without needing treatment. As long as your PSA levels remain stable and biopsies show no progression, surveillance can continue indefinitely. Some men stay on surveillance for the rest of their lives without the cancer ever becoming dangerous. Your monitoring schedule and test results will guide how long surveillance remains the right choice for you.
