Managing Changes in Taste and Smell During Melanoma Treatment

Changes in taste and smell are common side effects that can occur during cancer treatment, though they're not always discussed as much as other side effects. Let me explain what's happening and practical strategies to help.

Why This Happens

Different melanoma treatments affect taste and smell in different ways:

Immunotherapy (like nivolumab or pembrolizumab, which are commonly used for melanoma) can trigger immune system changes that affect your taste buds and smell receptors. Targeted therapy (such as BRAF inhibitors like dabrafenib/trametinib) and chemotherapy can damage taste and smell cells directly. Radiation therapy to the head or neck area can particularly affect these senses.

These changes typically happen because:

Treatment damages the cells responsible for taste and smell
Medications can alter how your brain processes these senses
Dry mouth (a common side effect) makes taste worse
Inflammation in your mouth and throat interferes with normal sensation

Practical Strategies to Help

For Taste Changes:

Experiment with flavors: Try stronger, more flavorful foods (citrus, ginger, mint, garlic) if food tastes bland
Adjust temperature: Sometimes cold foods taste better than hot ones, or vice versa
Use marinades and sauces: These add flavor to foods that might otherwise taste metallic or off
Avoid your favorite foods temporarily: Save foods you love for when your taste returns—you don't want to create negative associations
Try sugar-free candies or mints: These can help refresh your palate between meals
Use plastic utensils: Metal utensils can intensify metallic tastes some people experience

For Smell Changes:

Reduce cooking odors: Use a fan, open windows, or order takeout when cooking smells bother you
Keep foods covered: This minimizes odor exposure
Eat foods cold or at room temperature: Warm foods release more aroma
Try aromatherapy cautiously: Some people find pleasant scents (like lemon or peppermint) helpful, but avoid strong perfumes

General Nutrition Tips:

Focus on nutrition over taste: Protein shakes, smoothies, and nutritional supplements can help maintain nutrition when food doesn't appeal to you
Stay hydrated: Drink plenty of water, which also helps with dry mouth
Eat smaller, frequent meals: This is easier when appetite is affected
Ask about zinc supplements: Some evidence suggests zinc may help, but ask your doctor first
Keep a food diary: Track what works and what doesn't

When to Talk to Your Care Team

Contact your healthcare provider if:

You're losing weight or unable to eat enough
Changes in taste/smell are severely affecting your quality of life
You develop signs of malnutrition
The changes persist long after treatment ends (usually they improve within weeks to months)

Your oncology team can:

Refer you to a nutritionist or dietitian who specializes in cancer care—this is really valuable
Adjust medications if certain ones are contributing
Prescribe medications to help with dry mouth or other related issues
Rule out other causes (like infections)

The Good News

Most taste and smell changes are temporary. According to the American Cancer Society, these side effects typically improve gradually after treatment ends, though it can take weeks to months. Some people regain their senses completely, while others notice gradual improvement over time.
