6 Ways to Boost Immunity During Cancer Treatment

Your immune system is your body's natural defense, helping fight off germs and keeping you healthy. Cancer treatments are designed to target cancer cells, but they can sometimes harm healthy cells too.

Chemotherapy and radiation therapy can weaken your body’s immune system, lowering the number of white blood cells and making infections more likely. Certain surgeries can also affect your immune function.

While you can't fully control how treatment affects your immune system, you can adopt simple habits that support your overall health.

6 Ways to Boost Immunity During Cancer Treatment

During treatment, your care team carefully monitors your blood counts and immune health. They will help you manage side effects and reduce the risk of infections. 

Most treatment-related changes are temporary, and your immune system typically recovers after therapy ends. However, there are some things you can do to support your body through this process.

1. Eat Healthy

Just like an engine, your body needs the right fuel, especially during cancer treatment. A balanced diet gives your immune system the nutrients it needs, such as:

• Protein: Essential to build and repair body tissues, including immune cells
• Vitamins and minerals: Vitamins A, C, and E, along with minerals like zinc and selenium, help protect and strengthen your immune system

To support immunity, try to include fruits and vegetables, lean protein like chicken or fish, whole grains, and healthy fats, such as olive oil, in your daily meals.

 Every patient’s nutritional needs are different, especially during cancer care. It’s important to speak with your doctor or a registered dietitian who can create a plan tailored specifically for you.

2. Keep Moving

Gentle, regular activity helps boost your circulation, energy levels, mental health, and overall wellness during cancer treatment. Physical activity may even support your immune system’s ability to respond to germs.

Activities at a comfortable pace (walking, cycling, swimming, or yoga) are usually safe and beneficial. Aim for about 30 minutes of activity each day, three to five days a week, but always listen to your body.

• Brisk walking
• Cycling
• Swimming
• Gentle yoga or stretching

Before starting any exercise routine, it's important to get approval from your care team, especially if you're experiencing fatigue, weakness, or other side effects.

3. Sleep Well

Sleep is vital during cancer treatment because it allows your body to repair tissues and restore your immune system. When you're not getting enough quality sleep, your risk of infections and other health problems increases.

Cancer treatments can disrupt sleep because of pain, anxiety, or medication side effects. If sleep becomes difficult, try these simple tips:

• Keep a consistent bedtime and wake-up schedule, even on weekends.
• Create a calm, cool, quiet sleeping environment.
• Engage in gentle physical activity during the day, not right before bedtime.
• Avoid going to bed overly full or hungry.

If sleep remains a challenge, reach out to your care team. They can offer additional suggestions to help you rest better, supporting both your recovery and your immunity.

4. Manage Stress

When you're facing cancer, stress is common, but ongoing stress can weaken your immune system. Simple daily practices can make stress more manageable and ease your body's stress response.

Gentle activities can help you relax, lower stress hormones, and support your overall health:

• Deep breathing exercises or meditation
• Gentle yoga or mindfulness practices
• Listening to calming music or relaxing outdoors
• Talking openly with loved ones or joining a support group

If stress feels overwhelming, speak to your care team. They can connect you with a counselor or support group, giving you tools to feel calmer and stronger during your treatment.

5. Quit Tobacco and Alcohol

Quitting smoking and limiting alcohol intake can significantly improve your body's ability to cope during cancer treatment.

Smoking harms your lungs and increases your risk of infections. Even exposure to secondhand smoke weakens your immune system. Stopping smoking quickly improves lung function, reduces inflammation, and lowers the risk of illness.

When it comes to alcohol, moderation is key. If you choose to drink, follow recommended guidelines: no more than one drink per day for women and two for men.

6. Maintain Everyday Protection

Protecting yourself from infections during cancer treatment is critical, and some easy daily habits can help keep germs away:

• Wash your hands frequently with soap and water
• Avoid large crowds or people who are sick
• Ask your care team about recommended vaccines

These simple measures can greatly reduce your chances of catching an infection when your immune system is weaker.

When to Call Your Care Team

Always contact your care team promptly if you notice sudden signs of infection, such as fever, chills, or quickly worsening symptoms. They will guide you on the next steps and ensure you get prompt medical attention.

Small, everyday choices add up to a healthier immune system and better well-being during cancer treatment. Call 352-345-4565 or book an appointment with ACTC physicians for tailored advice about boosting your immunity safely.
