Dear Linda, PET scans can give a false positive but not a false negative...If there is hot spots its normally due to a form of malignancy, thus the biospy to determine which type...It really depends what type of Lymphoma your husband has ....The main thing is they have found something and are trying to rectify this....My thoughts and love are with you....Its easy for me to say try not to worry, I was in your position only a while ago, My husband is in remission from Non Hodgkins Lymphoma, and my mother has just passed with Lung cancer...If you need a friend email me ....
