[|Human|] Hello,My cousin was diagnosed with lung cancer 2 years ago. He had chemo and afterwards was OK for 2 years. This month he had a check up and oncologist found "a tissue" in his lungs that is not conclusive (or exclusive for malignancy). He may have to have bronchoscopy. Although I do not know any deitails I would appreciate if you explain what this "foreign" tissue may be.Thank you Margaret
[|AI|]  Hi, Thanks for writing in. There are many types of lung cancer depending on the cell type and area of involvement. Probably there is an area in the lung which might have cells which are different from the native cells present in the lung. This is possibly another type of cell growing in the lung. There are occasions when there is a particular type of tissue growing in the cells and secreting chemicals which are usually found in other areas. An example of such a tissue is neuroendocrine cell tumor. I am not sure about the type of cells in your cousin and that will be known only by doing a biopsy or bronchoscopy. Treating cancer is more of a team work than an individual treatment. The best hospitals for cancer treatment might be AIMS in the government funded ones and anagram hospital which is in private sector. Please make required inquiries on the doctors and hospitals. Please do not worry.
