What are the early signs of Melanoma recurrence

Early Signs of Melanoma Recurrence

I'm glad you're asking about this—knowing what to watch for is an important part of staying vigilant after melanoma treatment. Let me explain what recurrence means and what signs your care team wants you to monitor.

What is Melanoma Recurrence?

Recurrence means the melanoma has returned after treatment. According to the NCCN Guidelines for Patients: Melanoma, melanoma can come back in different locations:

• Local recurrence: Cancer returns in or near the original melanoma scar
• Satellite tumors: Small cancer deposits appear within or surrounding the original scar area
• In-transit recurrence: Cancer returns in the lymph vessels (tiny channels that carry fluid) between the original site and regional lymph nodes
• Nodal recurrence: Cancer returns in the lymph nodes near the original melanoma
• Distant metastasis: Cancer spreads to other parts of the body far from the original site

Early Warning Signs to Watch For

Skin Changes (Local/Satellite/In-Transit Recurrence)

According to NCCN Guidelines, watch for:

• A firm bump or nodule in or around the original melanoma scar
• New spots or lesions appearing between the original site and nearby lymph nodes
• Changes in appearance of the scar area (color, texture, or size changes)
• Skin thickening or hardening in the treated area

Lymph Node Changes (Nodal Recurrence)

• Enlarged lymph nodes in the lymph node basin (the group of lymph nodes closest to where your melanoma was located)—these may feel like firm bumps under the skin
• Swelling in the armpit, groin, or neck area (depending on where your original melanoma was)

General Signs of Spread

• New bumps or lumps anywhere on your body
• Unexplained weight loss
• Persistent fatigue or weakness
• Swelling in arms or legs (which could indicate lymphedema or lymph node involvement)

How Doctors Confirm Recurrence

If you notice any of these signs, your doctor will perform tests to confirm whether it's actually recurrence. According to NCCN Guidelines, these may include:

• Skin biopsy (removing a small sample of tissue to examine under a microscope)—this is the preferred method to confirm local recurrence
• Imaging tests (CT scans, PET scans, or ultrasound) to check for cancer spread
• BRAF mutation testing (if not already done) to guide treatment decisions

The ABCDE Rule for Self-Monitoring

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

• Asymmetry – One half doesn't match the other
• Border – Edges are irregular or hard to define
• Color – Not uniform throughout (may have patches of different colors)
• Diameter – Larger than 6mm (about the size of a pencil eraser)
• Evolving – The spot or mole changes in size, shape, or color over time

What You Should Do

According to NCCN Guidelines, your care team should:

• Examine your skin and lymph nodes at least once a year (more frequently if you're at higher risk)
• Teach you how to do self-exams of your skin and lymph nodes
• Explain what symptoms to report immediately

If you notice any of these signs:

1. Don't wait for your next scheduled appointment—contact your doctor right away
2. Take note of when you first noticed the change
3. Describe the location, appearance, and any symptoms (itching, bleeding, tenderness)
4. Ask for a biopsy or imaging if your doctor recommends it

Important Questions to Ask Your Care Team

• How often should I examine my skin and lymph nodes?
• What specific areas should I focus on during self-exams?
• If I find something suspicious, who should I call and how quickly can I be seen?
• What imaging or follow-up schedule is recommended for my specific stage and risk factors?
• Should I see a dermatologist (skin specialist) in addition to my oncologist?
