Possible: Very possible. Swelling may occur via a few different mechanisms in this illness: 1) if normal liver tissue has been replaced by cancer then insufficient circulating proteins can be produced by the liver resulting in a decrease in oncotic or "pulling pressure" of the circulating bloodstream resulting in fluid seeping out into dependent areas of body like the legs. 2) tumor bulk could block IVC
