See, in my practice in Ghaziabad, when I refer for an FDG PET-CT, I tell patients it's like a metal detector—it picks up any shiny, active cell, bhai. A false positive can be inflammation or infection lighting up, not just cancer. This Warburg effect they talk about? It's just that frantic hunger for sugar, like my neighbour's welding shop consuming power during peak hours—cancer cells do the same, hence the high SUV reading on the scan. But I've seen it light up in a simple tubercular lymph node too, making us chase shadows before the biopsy report comes in.
