> 1) I'd imagine so. Biology is too squishy for me, but from what I understand tumors are sites of abnormally rapid cell growth. Sounds like it would require lots of artery and capillary formation. Denser blood supply - more pings.
Also, cancer tissue has a greater metabolic rate, as the cells are rapidly dividing. It takes up and uses glucose faster than the tissue surrounding it. Thus, radiolabelled glucose, fluorodeoxyglucose (FDG), is used frequently in P.E.T. scans to identify tumors.
