[|Human|] could someone please help me understand this situation my grandpa is in right now, im really confused about it ? He is 72 years old and has been smoking for a very long time. He also coughs every now and then, he s been told bye several doctors that he has asthma in the past which was the cause for his coughing. He recently did a CAT SCAN and some other x-rays and they came back negitive for asthma, they actually told him he had water in his lungs . He was given medication for it and he was told that the water in his lungs was gone. He went to diffrent doctor and did a CAT SCAN and was told he had some kind of a shadow on his lungs/spot that is really tiny. The Doctor said it was nothing to worry about and that its just a spot left from the time he had lung infection. Now that same doctor is sending him on more tests, so he can find out the cause of this spot on his lungs?? I SPOKE TO HIS DOCTOR AND HE TOLD ME THAT ALL HE SEE S IS A SPOT ON THE LUNGS & HE DOESNT KNOW IF IT COULD TURN INTO ANYTHING SERIOUS - BUT, before i even spoke to him my, sister had told me that the doctor told her that this was some type of a tumor that was really small and that it could be easily taken care of with surgery because its not spreading right now can anyone tell me is it possible that this is not a tumor since not even the doctor know what it is 100%, he said theres a 50% chance that it might be something serious??? i meam hes this cough forever, and he had no other health problems except for this he does not wanna go to the doctors anymore, he eats good he hasnt changed at all. please give me an answer asap ,thanks for you time.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Yes, that spot can be other than tumor. Since he is a active smoker and aging above 70 years, malignant nodule is first possibility. But smoking can also cause fibrotic nodules in lungs. So in my opinion, the best approach for him is to wait and watch. Get done repeat CT scan after 6 months. If spot is of same size or regressing then no need to worry about malignancy. But if spot is increasing in size then biopsy is must for the diagnosis of cancer. Hope I have solved your query. I will be happy to help you further. Wishing good health to your grandfather. Thanks.
