Managing Taste and Smell Changes During Breast Cancer Treatment

Taste and smell changes are common side effects during breast cancer treatment, particularly with chemotherapy. These changes can affect your nutrition, enjoyment of food, and quality of life. Here's what you should know and practical strategies to help.

Why This Happens

Chemotherapy drugs can damage taste buds and affect your sense of smell in several ways:

  • Taste bud damage: Chemotherapy affects rapidly dividing cells, including those in your taste buds
  • Metallic taste: A common complaint, often described as a "metal mouth"
  • Smell sensitivity: Changes in how your nose processes scents, which affects how food tastes (since much of taste actually comes from smell)
  • Timing: These changes often begin during treatment and may persist for weeks or months after completion

Practical Strategies to Manage Taste Changes

Adjust Your Food Choices:

  • Try cold foods and smoothies (temperature can mask metallic tastes)
  • Use plastic utensils instead of metal (reduces metallic taste)
  • Marinate meats in acidic sauces (lemon, vinegar, tomato-based)
  • Experiment with stronger flavors: garlic, ginger, citrus, herbs, and spices
  • Add sauces and gravies to make foods more palatable
  • Try foods you don't normally eat—your preferences may shift temporarily

Manage Metallic Taste:

  • Rinse your mouth with salt water or baking soda solution before eating
  • Chew sugar-free gum or mints between meals
  • Drink plenty of water throughout the day
  • Avoid foods that taste metallic to you (often red meat)
  • Try chicken, fish, eggs, or plant-based proteins instead

Optimize Smell:

  • Eat foods at room temperature or slightly warm (hot foods release more aroma)
  • Avoid strong cooking smells—ask family to help with meal prep
  • Open windows while cooking
  • Try foods with milder aromas if strong smells bother you

Nutrition Tips During Taste Changes

Since taste changes can make eating difficult, focus on nutrition:

  • Eat small, frequent meals rather than three large ones
  • Prioritize protein (eggs, yogurt, nuts, beans) to maintain strength
  • Stay hydrated with water, broths, or smoothies
  • Keep nutritious snacks available for when you feel like eating
  • Don't force yourself to eat foods that taste unpleasant

When to Talk to Your Care Team

According to the NCCN Guidelines for Patients: Metastatic Breast Cancer, it's important to keep your healthcare team informed about side effects you're experiencing. Tell your care team about:

  • Significant taste or smell changes affecting your eating
  • Weight loss or difficulty maintaining nutrition
  • Persistent metallic taste or other taste disturbances
  • Any concerns about your ability to eat adequate nutrition during treatment

Your oncology team can:

  • Refer you to a registered dietitian who specializes in cancer nutrition
  • Suggest medications to help manage taste changes
  • Adjust your treatment plan if side effects become severe
  • Provide additional supportive care resources

Important Reminders

  • Taste changes are usually temporary and often improve after treatment ends
  • Everyone experiences these differently—what works for one person may not work for another
  • Keep trying different foods—your preferences may change week to week
  • Stay in close communication with your healthcare team about all side effects

Additional Support Resources

The NCCN Guidelines emphasize the importance of supportive care during cancer treatment. Ask your care team about:

  • Nutrition counseling services
  • Support groups for cancer patients
  • Recipes and meal planning resources
  • Mental health support if taste changes are affecting your emotional well-being
