Maintaining good nutrition during non-muscle invasive bladder cancer (NMIBC) treatment can help support your overall health and wellbeing. While nutrition alone cannot treat cancer, a balanced diet may help you maintain strength, manage treatment side effects, and support your immune system.


General Nutrition Guidelines


Focus on Nutrient-Dense Foods

  • Aim for a variety of colorful fruits and vegetables that provide antioxidants and phytonutrients

  • Choose whole grains like brown rice, oats, and whole wheat products for fiber and nutrients

  • Include lean proteins such as fish, poultry, beans, and tofu

  • Incorporate healthy fats from sources like olive oil, avocados, and nuts

According to the American Cancer Society, a balanced diet with plenty of fruits, vegetables, and whole grains may help cancer patients maintain strength during treatment (ACS, 2022).


Hydration

Staying well-hydrated is particularly important for bladder health. The Urology Care Foundation recommends adequate fluid intake to help flush the urinary system (Urology Care Foundation, 2023).


Managing Treatment Side Effects

Some NMIBC treatments may cause:

  • Bladder irritation

  • Changes in taste

  • Decreased appetite

  • Fatigue

Small, frequent meals and staying hydrated can help manage these effects (National Cancer Institute, 2023).


Foods That May Support Overall Health


Research from the World Cancer Research Fund suggests certain dietary patterns may support general health during cancer treatment (WCRF, 2024):

  • Mediterranean-style diets rich in plant foods, fish, and olive oil

  • Foods containing omega-3 fatty acids (fatty fish, walnuts, flaxseeds)

  • Foods high in antioxidants (berries, dark leafy greens, nuts)


Consult Healthcare Providers


Always discuss dietary changes with your healthcare team, as individual needs vary based on:

  • Your specific treatment plan

  • Personal health history

  • Medication interactions

  • Nutritional status

A registered dietitian with oncology experience can provide personalized guidance for your unique situation.
