Immunotherapy is a type of cancer treatment that works to help your immune system fight cancer.
The way you feel and any side effects that you may experience during immunotherapy depend on the type of cancer you have and how advanced it is. Other factors include how healthy you are before treatment as well as the type and dosage of treatment you receive. During immunotherapy treatment, you may face side effects that make it hard to eat the food your body needs to keep your strength up during treatment.
