Hi, I don't think I have the answer for u however from all of the research I have done it u generally have a primary cancer which spreads to other areas - especially the lung. I have lung cancer that has spread to the chest wall, lymph nodes, pelvis and posible liver (may just be a cyst tho -waiting the results). My cancer team said I have lung cancer that has metatisised. The problem with lung cancer is it doesn't show up on many scans until it 3cm or above. Depending on the type - if its an ademocarinoma (prob not right spelling) they generally grow slowly. However do spread to other areas fast. My lung tumour was 3cm x 2.9cm when first discovered, by lung surgery time it had grown to close to 5cm x 4cm (time lapsed was 3mths). They never imagined it was lung cancer due to my age hence all other tests were run and lots of waiting. How frustrating to not know and to have to wait to have these tests completed. Everyones experience of cancer is diferrent and this has only been my experience. I will pray they get these tests completed ASAP....I would assume by bronoscopy or by needle biopsy (i had both) to determine the lung legion type. Good luck and my thoughts are with you. Rubes ...
