 [ Symptoms ] i have been eating approx 12 of what i used to eat however my stomach is even bigger [ Disease ] most helpful answer i do not know anything about your medical history to give you an okay certain types of cancer especially those that may involve the liver and certain types of chemotherapeutic drugs that can cause liver effects may not permit acetaminophen use because your chemotherapy is soooooo important it would be wise to ask this very patient specific question directly to your oncologist do not take acetaminophen until you get the specific okay from your oncologist
