my husband was told he had stage iv squamous cell carcinoma of the lung in july 2011. In Jan.2012 he had went into remission but we just found out it shows an enlargememt in size from 5.0/3.0cm to 5.3/4.9cm. Im just really scared of looseing him, but can you tell me what we should expect next? There is greater mediastinal extension and surrounds the superior margin of the left main pulmonary artery. Suggest disease progression. A tiny pericardial effusion& 3 tiny nodular areas in right upper lobe are unchanged. his heart is the normal size& there is a trace amount of pericardial fluid. When we go in to see his doctor he never ask any questions& I feel like if he wanted to know things he'd ask, so I cant bring it to ask the questions.
