Prostate Cancer Management
Active Surveillance
Some prostate cancers grow so slowly that treating them causes more harm than watching them. Active surveillance is not doing nothing — it is a structured monitoring program with curative treatment held in reserve and started the moment it's warranted. For the right patient, it means avoiding the side effects of surgery or radiation, sometimes permanently, without giving up the chance of cure. Texas Regional Urology manages active surveillance at our offices in The Woodlands, Tomball, and Kingwood.
Monitoring With Intent
What Is Active Surveillance?
Active surveillance is a deliberate strategy for managing low-risk prostate cancer without immediate treatment. The cancer is monitored on a defined schedule, and if it shows signs of becoming more aggressive, curative treatment begins.
The reasoning comes from a fact about prostate cancer that surprises most people: many prostate cancers never become dangerous. A substantial number of men diagnosed with low-grade disease would live a full life and die of something else entirely, having never had a symptom. Meanwhile, surgery and radiation carry real and lasting side effects — urinary leakage, erectile dysfunction, bowel changes.
Treating a cancer that was never going to harm you means accepting all of the cost and none of the benefit. Active surveillance exists to avoid exactly that, without abandoning men whose cancer does turn out to be a threat.
The distinction from watchful waiting matters. Watchful waiting is a different strategy with a different goal: no intensive monitoring, no plan for curative treatment, and management of symptoms only if they develop. It suits men whose age or health means cancer treatment would do more harm than the cancer will. Active surveillance keeps cure on the table. Watchful waiting deliberately sets it aside. Your urologist will be explicit about which one you're on.

Why Men Choose It
Benefits of Active Surveillance
Avoiding Unnecessary Treatment
Many men on surveillance never require treatment at all, and never experience the side effects that come with it.
Preserved Urinary and Sexual Function
Surgery and radiation carry meaningful risks to continence and erectile function. Surveillance avoids them for as long as it lasts.
Cure Remains Available
If monitoring shows progression, curative treatment is still on the table. Surveillance defers treatment; it doesn't forfeit it.
Better Information Over Time
Repeat testing and imaging build a picture of how your specific cancer behaves, which is more informative than any single snapshot at diagnosis.
Equivalent Long-Term Outcomes for Low-Risk Disease
For appropriately selected men, long-term cancer-specific survival is comparable to immediate treatment.
Who Qualifies
Am I A Candidate?
Active surveillance is generally offered to men with low-risk prostate cancer: a low Gleason score or grade group, a limited amount of cancer in a small number of biopsy cores, a PSA in a favorable range, and a cancer that appears confined to the prostate. Some men with favorable intermediate-risk disease are also candidates, depending on the details.
Your overall health and life expectancy factor in, as does your own tolerance for living with an untreated cancer — which is a real consideration and not a small one. Some men are entirely comfortable with monitoring; others find it a source of ongoing anxiety that outweighs the benefit. Both responses are legitimate, and that conversation belongs in the decision.
Higher-grade cancers, larger cancer volume, rapidly rising PSA, or evidence of spread generally call for treatment rather than surveillance. Learn more about prostate cancer and elevated PSA.

What Monitoring Involves
What to Expect
PSA Testing
PSA is checked at regular intervals, commonly every three to six months. The trend over time matters far more than any single value.
Physical Examination
A digital rectal exam is performed periodically to check for palpable change.
Imaging
Multiparametric MRI is used to assess the prostate and identify areas of concern, and it can reduce how often biopsies are needed.
Repeat Biopsy
A confirmatory biopsy is usually performed within the first year or two of starting surveillance, with repeat biopsies at intervals thereafter or when PSA or imaging suggests change. MRI fusion biopsy allows targeted sampling of specific areas.
When to Change Course
Treatment is generally recommended if the Gleason grade rises, if substantially more cancer appears on biopsy, if imaging shows progression, or if PSA rises steadily. It is also entirely reasonable to switch to treatment because you no longer want to live with monitoring.
Your Schedule Is Individual
The intervals above are typical rather than universal. Your urologist will set a schedule based on your specific findings and adjust it as the picture develops.
Risks & Considerations
Trade-offs to Understand
The Cancer Can Progress
A minority of men on surveillance are found to have more aggressive disease than the initial biopsy showed, or their cancer progresses. Monitoring exists to catch this while cure is still available, and it usually does.
Repeat Biopsies
Surveillance means periodic biopsies, each carrying small risks of bleeding and infection. MRI has reduced how often they're needed but not eliminated them.
Living With an Untreated Cancer
For some men the ongoing awareness is genuinely difficult, and that is a valid reason to choose treatment. It should be weighed openly rather than dismissed.
It Requires Commitment
Surveillance only works if you keep the appointments. Men who drift away from the schedule lose the protection the strategy depends on.
Answers to your Active Surveillance Questions
Frequently Asked Questions
Not for genuinely low-risk prostate cancer.
Many low-grade prostate cancers grow so slowly they never threaten health, and treating them delivers side effects without benefit. Monitoring is designed to identify the minority that do progress, while cure is still available.
Surveillance keeps cure on the table.
Active surveillance monitors closely with intent to treat if the cancer progresses. Watchful waiting forgoes curative treatment and manages symptoms only, and is intended for men whose health makes treatment inadvisable.
Typically every three to six months.
PSA and examination happen at regular intervals, with imaging and biopsy at longer ones. Your specific schedule depends on your findings.
We move to curative treatment.
Rising grade, increasing volume, or progression on imaging generally prompts a shift to surgery or radiation. Because monitoring catches these changes early, treatment remains curative in the great majority of cases.
Yes, at any point.
Choosing surveillance doesn't lock you into it, and some men opt for treatment simply because monitoring becomes stressful. That's a legitimate reason and we'll support it.
No — it's an active, structured plan.
Surveillance involves scheduled testing, imaging, biopsies, and clinical assessment on a defined protocol. The alternative to treatment is not neglect.

Let's talk about whether treatment is necessary yet.
Bring your biopsy report and PSA history. A second opinion on whether you need treatment at all is always reasonable, and we're glad to provide one.
