What is active surveillance and when is it the right choice for cancer

Active Surveillance in Cancer Care

Active surveillance is a carefully monitored approach where patients with certain cancers are closely watched with regular testing and imaging instead of immediately starting treatment. It's a legitimate medical strategy for specific situations—not a "wait and see" approach, but rather "watch and measure."

How Active Surveillance Works

Rather than treating cancer right away, your care team:

• Schedules regular appointments (often every 3-6 months initially)
• Performs imaging scans (CT, MRI, PET) on a set schedule
• Monitors blood tests and tumor markers
• Watches for signs that the cancer is growing or changing
• Starts treatment promptly if progression is detected

The goal is to avoid unnecessary treatment while catching any changes early enough to treat effectively.

When Active Surveillance May Be Appropriate

Active surveillance is most commonly used for:

Early-Stage Prostate Cancer

• Low-risk prostate cancer (low PSA levels, low Gleason scores, small tumors) is a classic candidate. According to NCCN Guidelines for Prostate Cancer, active surveillance can be appropriate for men with localized, low-risk disease, as many of these cancers grow very slowly or not at all.

Early-Stage Breast Cancer

• Some ductal carcinoma in situ (DCIS) may be candidates. The American Cancer Society notes that for certain low-risk DCIS cases, active surveillance is being studied as an alternative to immediate surgery.

Certain Lymphomas

• Indolent (slow-growing) lymphomas like follicular lymphoma may not require immediate treatment. The Leukemia & Lymphoma Society indicates that "watch and wait" approaches are standard for asymptomatic, early-stage indolent lymphomas.

Thyroid Cancer

• Small papillary thyroid cancers may be monitored without immediate surgery in selected cases.

Why Choose Active Surveillance?

Potential benefits:

• Avoids side effects of treatment (surgery, chemotherapy, radiation) if cancer isn't progressing
• Reduces anxiety and life disruption for slow-growing cancers
• Preserves treatment options for later if needed
• May improve quality of life in the short term

Important considerations:

• Requires commitment to regular follow-up appointments
• Requires emotional tolerance for living with a cancer diagnosis without active treatment
• Works best for cancers known to grow slowly
• Requires a trustworthy relationship with your care team

When Active Surveillance Is NOT Appropriate

Active surveillance is generally not suitable for:

• Aggressive, fast-growing cancers
• Advanced-stage disease
• Cancers with high-risk features
• Patients who cannot tolerate the psychological stress of monitoring
• Situations where treatment delays could significantly impact outcomes

Questions to Ask Your Oncologist

If active surveillance is being discussed for your situation:

1. "Why is active surveillance appropriate for my specific cancer type and stage?"
2. "What are the specific criteria that would trigger starting treatment?"
3. "How often will I need appointments and imaging, and what will be monitored?"
4. "What is the risk that my cancer will progress during surveillance, and how would we catch it?"
5. "What are my alternatives, and why is active surveillance better than immediate treatment in my case?"
6. "If I start active surveillance and change my mind, can I switch to treatment?"

The Bottom Line

Active surveillance is a valid, evidence-based approach for specific, carefully selected cancers—particularly slow-growing types caught at early stages. It's not about avoiding treatment indefinitely; it's about avoiding unnecessary treatment while maintaining close oversight. The NCCN Guidelines across multiple cancer types recognize active surveillance as an appropriate option when specific clinical criteria are met.

However, whether it's right for you depends entirely on your cancer type, stage, risk factors, and personal preferences. This is a decision that requires detailed discussion with your oncology team.
