hi, my boyfriend who has stage 4 lung cancer has inadvertently ingested kerosene (it got in his mouth while he was filling a heater, and he spit it out). I t seems since it happened 4 days ago he has had a bed cough and a lot of phlem. Should he go to the doctor???

### output:

HI THANKS FOR POSTING YOUR QUERY. I AM EXTREMELY SORRY TO HEAR THAT YOUR BOYFRIEND IS IN "STAGE4 CANCER LUNG".ANY STAGE 4 CANCER IS MORE PRONE TO GET INFECTIOUS COMPLICATIONS. ACCIDENTAL SWALLOWING OF ORGANIC SOLVENTS IS MORE PRONE TO GET "ASPIRATION PNEUMONIA", WHICH CAN PRESENT WITH EXCESS COUGH AND SPUTUM.ALL SUCH CASES CAN BE TREATED WITH PROPHYLACTIC "RESPIRATORY ANTIBIOTICS" LIKE TAB MOXIFLOXACIN 400 mg once a day for 7 days. A CHEST X-ray IS NEEDED TO EVALUATE THE EXTENT OF LUNG INVOLVEMENT.IN YOUR CASE THE RISK OF PNEUMONIA IS QUITE LOW AS HE HAS SPIT MOST THE KEROSENE HE INGESTED.CONSIDER A "FLEXIBLE BRONCHOSCOPY" IN CASE IF SYMPTOMS DOES NOT RESOLVE BY 1 WEEK.THIS CAN RULE OUT THE PRESENCE OF INFECTION AND GRANULOMA FORMATION.REVIEW WITH YOUR ONCOLOGIST TO Assess THE LUNG CANCER PATHOLOGY.CONCLUSIVE OPINION:LOW RISK OF LUNG INFECTION IN YOUR CASE.NEED FOLLOW UP.THANK YOU.
