I m a 60 year old male,6 1 ,178 pds,no previous serious illnesses. End of januari I began coughing up a little blood in my phelm. Had an X-ray and an antibiotic cure(augmentin) which didn t work. Since mid-februari I ve been thru various tests in hospital- X-rays, CT scan, broncosopy with lavage,angioscopy, PET scan, sputum test, blood tests. All without result, i.e. diagnosis. I m told it could be anything- infection to cancer; the only thing I m sure of is that it isn t TB. I been advised by my lung doctor to have a lobectomy(upper right lobe) because of the danger of possible excessive bleeding in the future. This danger of bleeding is the reason given for not performing a biopsy. Is it normal to proceed to operation whilst there is still no definite diagnosis of the problem? Tanking you in advance, Campbell Macintyre
