Cough in a patient undergoing chemotherapy can mean many different things. first, it is possible for cough to be a side effect of certain chemotherapy drugs. Evaluating whether this is a possibility would require a close analysis of the chemotherapy drugs a patient received as well as the timeline of when the cough started relative to the chemotherapy administration.
Second, many chemotherapy medications (and cancer itself) can depress a person's immune system and make infections more likely. A cough can be a sign of a developing respiratory infection, especially if it is accompanied by fever
, chills, or coughing up sputum.
Metastatic cancer to the lungs can also cause symptoms, possibly including cough. Evaluating this possibility would likely require further physical exam, history, and even imaging studies.
Overall, cough in a patient with cancer who is undergoing chemotherapy could mean several different things. The cough could be an insignificant symptom that will pass, or it could be a sign of more serious illness
. For that reason, it is best to have such symptoms evaluated by a physician, preferably the treating oncologist.
