I certainly would ask the doctor for a least a better explanation of what he HAS told you. That there is an abnormality in the lung (s) could have told you so much more, if he had elaborated, and I think that it is worth the time to ask him directly for further explanation. How big is the abnormality? Is it diffused or with defined boarders? etc. These answers will tell you some things. A cyst for instance MAY present in a radiograph as something very hard edged (defined boarders) a cancer MAY appear more diffused. These are not absolutes, but it would not be out of line to ask him for an opinion on what this may be. Surely he could be more forthcoming. You asked if it could be cancer, I am surprised that he did not address this question. The answer is yes, but it could also be something BENIGN such as a cyst. The lungs and the aerodigestive tract in general are the primary locations for an oral cancer metastasis. There must be some baseline radiographs or scans from her previous surgery. How does the current scan differ from those? With a rather extensive primary cancer, your mother had a surgical only treatment protocol, here in the US; it is likely that her surgery would have been followed by radiation. You might ask the doctors about her original treatments, and IF there is a spread of the cancer, what treatment options there are available for her.

It is the responsibility of medical professionals to provide us with enough information for us to completely understand the situation; how else can we make informed decisions? It appears this wasn
