My husband had knee surgery in Jan chest xray was clear, he had another a week ago and the surgeon said there was a \"spot\" on his lower left lung and he is going for a ct scan tomorrow, he has been having headaches mri on head was clear, he also has type to diabetes and diabetic neoropthy, he is a smoker, has not been sick at all, what could be causes of the spot
Thanks for your question on Chat Doctor. I can understand your concern. Since your husband is diabetic and active smoker, we should definitely rule out lung cancer and lung infection for his spot on chest x-ray. Diabetes decreases lung defense system and so makes individual prone for lung infections. Smoking is the biggest risk factor for lung cancer. So get done CT thorax and bronchoscopy for the diagnosis of lung cancer and lung infection. Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
