Infectious Diseases Cancer Patients Should Beware

Cancer patients—especially those undergoing chemotherapy, radiation therapy, or bone marrow transplants—often have weakened immune systems. This makes them more susceptible to infections, which can lead to serious complications. Recognizing and avoiding infectious diseases is essential for safe and successful cancer treatment.

5 Infectious Diseases to Watch Out For

1. Influenza

Spread through respiratory droplets from coughing or sneezing
Can lead to severe pneumonia in immunocompromised patients
Annual flu vaccination is highly recommended

2. Bacterial Pneumonia

Caused by bacteria like Streptococcus pneumoniae
Affects the lungs and respiratory system
Pneumococcal vaccination is advised

3. Tuberculosis

Transmitted via airborne droplets from infected individuals
High risk for lung cancer patients or those on immunosuppressants
Pre-treatment TB screening is recommended

4. COVID-19

Cancer patients infected with COVID-19 are at high risk of severe disease and death.
Avoid crowded places, wear a mask, and wash your hands regularly.

5. Aspergillosis (Lung Fungal Infection)

Caused by inhaling fungal spores from the environment
Common in patients undergoing chemotherapy or bone marrow transplants
Avoid dusty or moldy areas, especially during treatment

How to Prevent Infections

Wash hands regularly with soap or alcohol-based sanitizer
Wear a face mask when going outside or in public spaces
Get vaccinated as per your doctor’s recommendations
Avoid raw or unclean foods
Maintain distance from people who are coughing or have a fever
Schedule regular check-ups to monitor for signs of infection

Infections can interrupt cancer treatment or worsen patient outcomes. Being cautious and following preventative guidelines can help cancer patients stay protected and continue their treatment without complications.
