What Happens If You Choose No Treatment for Prostate Cancer?
This is an important question, and the answer depends heavily on what type of prostate cancer you have—which is why your specific diagnosis matters so much.
THE KEY DISTINCTION: Risk Level Determines Everything
According to the CancerPatientLab webinars on prostate cancer treatment, doctors typically categorize prostate cancer along two critical dimensions:
- How advanced it is (localized vs. metastatic—meaning spread beyond the prostate)
- How aggressive it is (based on Gleason score and other factors)
This distinction is crucial because "no treatment" means very different things depending on where you fall.
SCENARIO 1: Low-Risk, Localized Prostate Cancer
If you have truly low-risk disease (like Gleason 6), watchful waiting or active surveillance may actually be appropriate.
According to the webinars, men with low-grade cancers confined to the prostate often don't need immediate treatment. As one expert noted: "somebody who is truly a Gleason 6 doesn't really have to worry about it."
What happens:
- Your cancer grows very slowly (if at all)
- Many men with Gleason 6 never experience symptoms or progression
- You avoid the side effects of surgery or radiation
- You get regular monitoring (PSA blood tests, imaging, sometimes biopsies)
- If signs of progression appear, you can start treatment then
This is NOT the same as "ignoring" cancer—it's active surveillance with regular check-ups.
SCENARIO 2: Intermediate or High-Risk Localized Cancer
If you have higher-risk disease confined to the prostate and choose no treatment, progression is likely.
The webinars emphasize that treatment intensification is now standard of care for more aggressive cancers. Without treatment:
- Your cancer will likely grow over time
- It may eventually spread beyond the prostate (become metastatic)
- You may develop symptoms like urinary problems, bone pain, or fatigue
- Your treatment options later may be more limited and harder on your body
- Your long-term survival is typically reduced
SCENARIO 3: Metastatic Prostate Cancer (Spread Beyond the Prostate)
If your cancer has already spread and you choose no treatment, progression is typically rapid.
According to the treatment guidelines discussed in the webinars:
- Without treatment: PSA levels usually rise steadily, cancer spreads to more bones and organs, symptoms worsen, and survival is significantly shortened
- With treatment: Modern therapies can control the disease for years, maintain quality of life, and extend survival substantially
The webinars note that for metastatic disease, "treatment intensification is now standard of care," involving combinations of:
- Androgen deprivation therapy (hormone therapy)
- Chemotherapy (like docetaxel)
- Newer targeted drugs (AR inhibitors, PARP inhibitors, immunotherapies)
QUALITY OF LIFE CONSIDERATIONS
An important theme in the webinars is that quality of life matters alongside survival. Some key points:
- If on active surveillance: You maintain normal hormone levels, sexual function, and energy—but need regular monitoring
- If untreated with aggressive cancer: You may experience pain, urinary symptoms, fatigue, and emotional distress as disease progresses
- If treated: You may have temporary side effects, but disease control often improves overall quality of life
WHAT YOU SHOULD ASK YOUR DOCTOR
Since "no treatment" means different things depending on your specific situation, ask your oncologist:
- "What is my Gleason score and stage? Is my cancer low-risk, intermediate-risk, or high-risk?"
- "Is active surveillance (monitoring without immediate treatment) appropriate for me, or do I have aggressive disease that needs treatment?"
- "If I don't treat now, what is the likely timeline for progression, and what symptoms might I experience?"
- "What are my treatment options if I choose to wait, and would they be different later?"
- "How will we monitor my cancer if I choose active surveillance?" (PSA tests, imaging, biopsies, how often?)
THE BOTTOM LINE
There's a big difference between:
- ✅ Active surveillance (appropriate for some low-risk cancers—regular monitoring, treatment if needed)
- ❌ Ignoring cancer (not monitoring, not treating aggressive disease—typically leads to progression)
According to the CancerPatientLab webinars, the modern approach emphasizes personalized medicine—matching treatment intensity to your specific cancer's risk level. For some men, that means no immediate treatment. For others, it means aggressive, combination therapy.
Your specific diagnosis determines everything. The webinars stress that most men in community practices aren't getting adequate testing to determine their cancer's true characteristics, which makes this decision even more important.
