If you are living with a cancer diagnosis, navigating life during a viral outbreak can feel overwhelming and frightening. You might have many questions and worries running through your mind every single day. Thoughts like "What will happen to me if I catch this virus?" or "Can I still take my regular cancer medicines?" are completely normal. It is very important to think about these things carefully because viral infections can pose unique challenges during cancer care.
For cancer patients, the risk of developing severe illness from COVID-19 is higher than it is for the general population. Understanding how your body reacts, how treatments are managed, and how you can stay safe will help you feel more in control. Let us break down everything you need to know in clear, simple terms so you can protect your health and peace of mind.
Key Takeaways for Cancer Patients
- Cancer and certain cancer treatments can weaken your immune system, making infections harder to fight off.
- Your doctor will carefully weigh the risks and benefits before making any changes to your cancer treatment plan.
- Strict daily hygiene practices, wearing face masks, and practicing physical distancing are your best lines of defense.
- Knowing COVID-19 symptoms and staying in regular contact with your healthcare team is essential for your safety.
- Immunocompromised people may not always develop a fever when infected, so watch for other respiratory signs.

COVID-19 and Your Immune System
To understand why COVID-19 requires extra caution, we must first look at how your immune system works. Simply put, if you have cancer, your body has a higher chance of catching various infections. This happens because the normal, healthy activity of your immune system becomes compromised or weakened.
Think of your body's immune system as a dedicated defense army protecting a country. This internal army fights off outside enemies like viruses, bacteria, and other harmful germs. When this army is strong, it keeps you safe from getting sick. When it is weak, invaders can enter and cause severe illness much more easily.
When you have cancer, the disease itself can sometimes weaken this protective army. In other situations, the medical treatments you receive to fight the cancer are what lower your defenses. For example, treatments like chemotherapy or bone marrow transplants work by reducing the number of white blood cells in your body.
These white blood cells act as the main soldiers in your body's defense army. When chemotherapy lowers your white blood cell count, your body loses its primary fighters. As a result, if a virus like COVID-19 enters your body, your immune system may struggle to fight it off quickly.
Even if you are a cancer survivor who has finished active treatment, your immune system may still need time to recover fully. Because your body is still rebuilding its strength, you must continue taking extra precautions to protect your health. Always consult your doctor to understand your personal risk level.
Also, certain types of cancer can directly affect vital organs like your lungs or kidneys. When an organ is weakened by disease, your body has an even harder time fighting off respiratory illnesses. While many people with COVID-19 experience mild symptoms, cancer patients face a much higher risk of severe complications.
How COVID-19 Affects Cancer Treatments
Many patients worry about how the pandemic might impact their scheduled medical appointments and therapy sessions. A very common question is whether you will need to stop taking your medicine. The answer depends on several unique factors related to your health and local conditions.
If COVID-19 cases are surging in your local area, your doctor will evaluate your situation very carefully. Your medical team will discuss whether to continue your treatments as planned or briefly delay them. Sometimes, postponing non-urgent therapy helps protect you from visiting busy hospitals where virus exposure is higher.
However, in many cases, continuing your cancer treatments without interruption is vital for your survival and recovery. When making this decision, your oncologist will look at your specific cancer type, its current stage, and your overall health status. You should never stop or alter your medicines on your own without talking to your doctor first.
If you have not started your cancer treatments yet, your medical team will determine the safest time to begin. They will weigh the urgency of treating your cancer against the current viral risks in your community. If you are participating in a clinical trial, ask your research team if the study is still active or temporarily paused.
Open communication with your oncology team is your best tool during this time. Share any worries you have about visiting the clinic or hospital. Your doctor can explain the safety measures in place at the medical facility to keep you protected during your visits.
How to Protect Yourself
Living with a cancer diagnosis means you must be much more vigilant about personal safety during viral outbreaks. Here are practical steps you can take every day to lower your risk of catching COVID-19:
- Stay home unless it is absolutely necessary to go out for medical care or emergencies.
- Wash your hands often with soap and water for at least 20 seconds, especially after touching public surfaces.
- If soap and water are not available, use an alcohol-based hand sanitizer that contains at least 60 percent alcohol.
- Keep a safe physical distance of at least 2 meters (about 6 feet) away from people outside your household.
- Regularly clean and disinfect high-touch surfaces in your home, such as doorknobs, light switches, counters, and your mobile phone.
- Avoid touching your eyes, nose, and mouth with unwashed hands to prevent germs from entering your body.
- Stock up on a multi-week supply of your essential prescription medicines and household goods so you do not need to go out often.
- Wear a well-fitting face mask whenever you must leave your home or interact with others in indoor public spaces.

Maintaining regular communication with your healthcare team is vital, whether you are currently receiving active treatment or resting between cycles. Ask your hospital or clinic if they offer telemedicine visits so you can consult your doctor from the comfort of your home.
It is equally important to recognize the common signs and symptoms of COVID-19 so you can act quickly if something feels wrong. Review the common symptoms listed below and monitor how you feel every day.

| Sore Throat | Scratchy or painful throat making it hard to swallow food or water. |
| Loss of Taste or Smell | Sudden loss of your sense of taste or ability to smell food. |
Important Reminder for Immunocompromised Patients
Crucial Warning: If you are receiving active cancer treatments, your weakened immune system may not always produce a fever when you get infected. Because of this, you might not feel hot or show a high temperature even if you are sick. Always monitor yourself for other warning signs like coughing, breathing trouble, or extreme fatigue, and do not rely on fever alone as your main indicator.
If you suspect you are showing any COVID-19 symptoms, contact your doctor right away. Your medical team will review your symptoms and decide if you need a diagnostic test. If your symptoms worsen rapidly, seek professional medical help right away without delay.
When to Call Emergency Services (Red Flag Symptoms)
Get emergency medical help right away if you or your loved one experience severe warning signs:
- Severe trouble breathing or gasping for air.
- Persistent pain or heavy pressure in your chest.
- New confusion, disorientation, or trouble waking up.
- Pale, gray, or blue-colored skin, lips, or nail beds.
Call 911 (US/Canada), 999 (UK), or go to your nearest Emergency Department (ER / A&E) right away.
