<s>[INST] hi my father in law recently and finally gone to the doctor he has a very nasty cough with allot of flem and we discovered there is blood also in it the doctor sed his lungs has shrunk and did test for Tuberculosis but was negative but now he has to go for a scan. Should we prepare ourselves for the worst, Cancer of the lungs? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Shrunken lung is commonly seen with cancer, old tuberculosis etc. He is also having hemoptysis (blood in sputum). Hemoptysis is commonly seen with cancer. So yes possibility of lung cancer is more in his case. So better to get done CT thorax to confirm this. You should prepare yourself for the diagnosis of lung cancer in him. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father-in-law. Thanks. </s>
