What are the signs that Melanoma has recurred

Signs That Melanoma Has Recurred

Melanoma recurrence means the cancer has returned after treatment. According to the NCCN Guidelines for Patients: Melanoma (2025), it's important to know what signs to watch for, since early detection of recurrence can affect your treatment options.

Types of Recurrence and Their Signs

Melanoma can recur in different locations, and each type has distinct characteristics:

Local Satellite and In-Transit Recurrence

These are the most common types of recurrence near the original melanoma site:

• Local satellite recurrence: A firm bump or nodule that appears within or around the original melanoma scar
• In-transit recurrence: New tumors that develop between the original melanoma site and the regional lymph nodes (the lymph nodes closest to where the cancer started)

Both types involve cancer that has returned in the lymph vessels of the skin. They may feel like firm bumps and can appear as new spots or growths in these areas.

Nodal Recurrence

This occurs when cancer returns in the lymph nodes:

• Enlarged lymph nodes in the lymph node basin (the group of lymph nodes closest to where your original melanoma was located)
• These may be noticeable as swelling in the armpit, groin, neck, or other areas where lymph nodes are located

Distant Metastatic Recurrence

Cancer that spreads to distant parts of the body may cause:

• New skin lesions in areas far from the original site
• Symptoms depending on where the cancer has spread (lungs, brain, liver, bones, etc.)

Self-Monitoring: The ABCDE Rule

According to the NCCN Guidelines, between your regular doctor visits, you should monitor your skin using the ABCDE rule to catch any changes early:

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

What to Do If You Notice Signs

The NCCN Guidelines recommend:

1. Report any changes to your healthcare provider immediately – Don't wait for your next scheduled appointment
2. Your doctor may perform a skin biopsy – This is the preferred way to confirm whether a spot is truly cancer recurrence
3. Additional testing may be needed – Depending on what's found, your doctor might order imaging tests (like CT scans or PET scans) to check if cancer has spread

Key Points to Remember

• Recurrence can happen months or even years after your initial treatment
• Regular self-exams are crucial for early detection
• Your care team will likely recommend follow-up exams at least once every 2 years, but this depends on your specific situation
• Any new or changing skin lesion should be evaluated by your healthcare provider

Questions to Ask Your Healthcare Team

1. How often should I examine my skin for changes?
2. What specific areas should I pay special attention to during self-exams?
3. If I notice something suspicious, who should I contact and how quickly?
4. What imaging or testing will I need during follow-up care?
5. Are there any warning signs specific to my stage or type of melanoma that I should know about?
