What is Immunotherapy?
The immune system is your body’s natural defense system. It searches the body for potential threats like infections. But, cancer cells have found ways to hide from immune cells. This allows cancer cells to grow without being detected and spread throughout the body. Immunotherapy is different from chemotherapy. Chemotherapy attacks cancer cells directly, while immunotherapy re-programs your immune system to do the work of finding and killing cancer cells.

Before Starting Immunotherapy
Before you begin immunotherapy, it’s important you tell your doctor if you:
- Have an autoimmune disease
- Have had an organ or stem cell transplant
- Have breathing problems
- Have liver disease
- Are pregnant or plan to become pregnant
- Are breastfeeding or plan to start breastfeeding
Be sure to also tell your doctor your complete medical history, including any changes in medications. Once you begin immunotherapy, it’s very important that you keep all your scheduled appointments. Taking regular and consistent doses is critical.
Because of how immunotherapy might affect your system, it’s important to tell every doctor taking care of you that you’re on immunotherapy. This includes:
- Your primary care provider (PCP)
- Hospital staff
- Emergency Room and Urgent Care staff
- Any other doctors or specialists
Fox Chase Cancer Center will give you an Immunotherapy Identification card with our contact information on it. Be sure to show this card to anyone who will be treating you for any reason. We encourage providers to contact us for more information or if they have any questions about your care.
Side Effects of Immunotherapy
Immunotherapy can come with different side effects than chemotherapy or other infusion treatments. You may experience any of the following side effects:
- Feeling extremely tired or weak
- Cough or shortness of breath
- Flu-like symptoms like fever, chills, or cough
- Loss of appetite
- Skin rashes, or itching
- Muscle, bone, or joint pain
- Chest or abdominal pain
- Diarrhea
- Headache
- Yellowing of your skin or eyes
- Confusion
Because immunotherapy medications change the way the immune system works, it’s very important to report all side effects to your treatment team, especially symptoms that are new or affecting your daily life. Side effects can turn more serious if not prevented correctly, or stopped early. Having side effects does not necessarily mean you will have to stop your treatment. It’s possible to reverse some symptoms if they are caught early, and many times, they be treated with other medicines.
These problems can begin anytime during immunotherapy treatment or even after your treatment has ended, which is why you’ll be closely monitored during and after treatment.
