How will we monitor my melanoma after initial treatment? What types of scans or tests will I need, and how often?...

Monitoring Your Melanoma After Treatment

I'm glad you're thinking ahead about follow-up care—this is a crucial part of your melanoma journey. Let me walk you through what monitoring typically looks like, based on current medical guidelines.

1) Follow-Up Monitoring Schedule and Exams

According to the NCCN Guidelines for Patients: Melanoma (2025), your follow-up care will depend on your specific stage and risk factors. Here's what you should expect:

Regular Clinical Exams

Your healthcare provider will examine your skin and lymph nodes regularly. The NCCN Guidelines recommend that your provider examine you at least once every 2 years, though many patients with higher-risk melanoma are seen more frequently (sometimes every 3-6 months, depending on your situation).

Why this matters: Your doctor is looking for:

• New skin lesions or changes to existing moles
• Enlarged lymph nodes in the areas near your original melanoma
• Any signs that melanoma has returned

How Often You'll Be Monitored

According to NCCN Guidelines, how often you receive follow-up testing depends on how likely it is that the cancer will return. This means:

• Lower-risk patients (early stage, completely removed) may need less frequent visits
• Higher-risk patients (deeper tumors, lymph node involvement) typically need more frequent monitoring

Your oncologist will explain your specific risk level and create a personalized schedule for you.

2) Types of Scans and Imaging Tests

The NCCN Guidelines note that imaging tests may be used, but the specific types depend on your stage and features. Here's what you should know:

Imaging Options

The guidelines mention that imaging to assess cancer signs or symptoms may be recommended, which can include:

• CT scans (computed tomography) - uses x-rays from many angles to create detailed pictures of the inside of your body
• PET scans - can show areas of increased activity that might indicate cancer
• Ultrasound - may be used to check lymph nodes

Important context: Not every patient needs imaging at every visit. Your doctor will determine what's appropriate based on:

• Your original tumor stage and depth
• Whether lymph nodes were involved
• Your symptoms or concerns
• How you're doing overall

Self-Monitoring at Home

This is equally important. The NCCN Guidelines emphasize that your care team should explain how you can do self-exams of your skin and your lymph nodes between office visits.

3) Signs of Recurrence to Watch For

This is critical information. According to the NCCN Guidelines, melanoma can recur in several ways, and knowing what to look for helps catch it early when it's most treatable.

Types of Recurrence and Warning Signs

Local Recurrence (in or near the original scar):

• A firm bump or nodule in or around the original melanoma scar site
• Changes in the appearance of the scar area
• Any new growth in that location

Satellite or In-Transit Recurrence (between the original site and lymph nodes):

• Small tumors appearing in the skin between where the original melanoma was and your regional lymph nodes
• These may appear as firm bumps along the lymphatic vessels

Nodal Recurrence (in lymph nodes):

• Enlarged lymph nodes in the lymph node basin closest to where your melanoma was located
• Swelling or lumps you can feel under the skin

Distant Recurrence (spread to other parts of the body):

• New lumps or bumps anywhere on your body
• Persistent cough or shortness of breath (if lungs are involved)
• Headaches or neurological symptoms (if brain is involved)
• Abdominal swelling or digestive changes (if organs are involved)

The ABCDE Rule for Skin Self-Exams

The NCCN Guidelines recommend using the ABCDE rule to monitor your skin between doctor visits:

• Asymmetry – One half of a mole doesn't match the other half
• Border – Edges seem irregular and are difficult to define
• Color – Not uniform throughout (may be brown, black, or patches of pink, red, white, or blue)
• Diameter – Larger than 6 mm across (about the size of a pencil eraser)
• Evolving – The spot or mole changes its size, shape, or color over time

The "Ugly Duckling" sign is also important: a spot that looks different from other spots on your skin.

Lymph Node Self-Exams

The NCCN Guidelines note that your provider should teach you how to examine your own lymph nodes. You're looking for:

• Lumps or swelling in the lymph node basin near your original melanoma
• Nodes that feel hard, fixed (don't move), or tender
• Any new lumps you haven't noticed before

4) What to Do If You Notice Something

If you find an unusual spot or notice swelling:

• Don't panic, but don't wait either
• Contact your dermatologist or oncologist promptly
• Describe what you found and when you first noticed it
• Your doctor may recommend a biopsy (removal of a small tissue sample) to confirm whether it's cancer

According to the NCCN Guidelines, testing for recurrence includes options like core biopsy (the preferred option) or imaging to assess cancer signs or symptoms.

Questions to Ask Your Care Team

Based on the NCCN Guidelines, here are specific questions that will help you understand YOUR personalized plan:

1. "Based on my stage and risk factors, how often should I come in for follow-up exams?"

2. "Will I need imaging scans (CT, PET, or ultrasound)? If so, how often and why?"

3. "Can you teach me how to do self-exams of my skin and lymph nodes, and what specific areas should I focus on?"

4. "If I find something concerning between appointments, who should I call and how quickly can I be seen?"

5. "What symptoms or changes should prompt me to contact you immediately rather than waiting for my next scheduled visit?"

6. "How long will I need this level of monitoring, and will it change over time?"

Summary

What we know from strong evidence:

• ✅ Regular skin and lymph node exams are essential (at least annually, often more frequently)
• ✅ Self-exams using the ABCDE rule are an important part of monitoring
• ✅ Imaging may be used based on your individual risk factors
• ✅ Several types of recurrence can occur, each with specific warning signs
• ✅ Early detection of recurrence significantly improves treatment options

What varies by individual:

• Your specific monitoring schedule depends on your stage, depth of tumor, and lymph node involvement
• The types and frequency of imaging will be personalized to your situation
• Your doctor will determine the best approach for YOUR case

The key takeaway from the NCCN Guidelines is that you play an active role in your care. By learning to recognize changes in your skin and lymph nodes, and by keeping your appointments, you're giving yourself the best chance of catching any recurrence early.
