Needle biopsy in lungs shows lungs carcinoma after operation its show nothing how ? can u have idea why

Good outcome: It appears your initial biopsy had findings that raised concern for cancer but that concern was laid to rest after actual material was obtained at operation. This type of misleading finding on a needle biopsy can come from a lot of non cancerous conditions such as infection, non specific inflammation etc. I am happy for you that the final outcome was good.
