Alex Spira, MD, PhD, FACP of Virginia Cancer Specialists, Fairfax, VA discusses side effects of immunotherapy in lung cancer. Dr Spira explains that side effects from immunotherapy are less severe than from chemotherapy and traditional drugs. However, side effects are real and can make patients very ill. Therefore, it is important to educate healthcare professionals about the side effects so that they can identify them early.
