What are the most common side effects of Melanoma treatment

Common Side Effects of Melanoma Treatment

The side effects you might experience depend on which type of treatment you receive. Let me walk you through the most common ones for each major treatment approach.

Surgery Side Effects

Surgery is often the primary treatment for melanoma, especially in earlier stages. Common side effects include:

• Pain and discomfort at the surgical site
• Swelling and bruising around the incision
• Scarring (permanent, though surgeons try to minimize this)
• Numbness or tingling if nerves are affected during surgery
• Lymphedema (swelling in the arm or leg) if lymph nodes are removed—this happens because lymph fluid can build up when lymph vessels are disrupted

Immunotherapy Side Effects

According to the NCCN Guidelines for Patients: Melanoma, immunotherapy drugs like checkpoint inhibitors (pembrolizumab and nivolumab) work by "freeing T cells to kill tumor cells." However, this immune activation can cause side effects:

Common side effects:

• Fatigue (tiredness)
• Skin reactions (rash, itching, redness)
• Flu-like symptoms (fever, chills, body aches)
• Nausea and loss of appetite
• Diarrhea or constipation
• Headaches

More serious (but less common) side effects:

• Autoimmune reactions where your immune system attacks healthy organs (lungs, liver, kidneys, or thyroid)
• Inflammation of the heart muscle
• Severe allergic reactions

Radiation Therapy Side Effects

According to the NCCN Guidelines, radiation therapy can cause:

• Sunburn-like skin problems in the treated area
• Changes in skin color (darkening or lightening)
• Hair loss around the area where radiation is given
• Fatigue (often develops over time)
• Nausea if the radiation is aimed at the abdomen (belly area)

The good news is that most radiation side effects are temporary and fade after treatment ends.

Targeted Therapy Side Effects

If you have a BRAF mutation, you might receive targeted drugs like dabrafenib/trametinib. These can cause:

• Skin rashes and sensitivity to sun
• Diarrhea
• Nausea
• Joint or muscle pain
• Fever
• Eye problems

T-VEC (Intralesional Therapy) Side Effects

T-VEC is a virus-based treatment injected directly into melanoma tumors. Side effects typically include:

• Pain, swelling, or redness at the injection site
• Flu-like symptoms
• Fatigue
• Chills

Managing Side Effects

Here's what's important to know: Most side effects can be managed or prevented. Your care team has medications and strategies to help. Some side effects improve on their own as your body adjusts to treatment.

Questions to Ask Your Healthcare Team

Since side effects vary based on YOUR specific treatment plan, ask your doctor:

1. Which side effects are most likely with my specific treatment?
2. When should I call you about a side effect—which ones are serious?
3. What medications or strategies can help manage side effects?
4. Are there any side effects that might require stopping treatment?
5. How long do side effects typically last after treatment ends?
