For cancer patients, there is often a recommendation to limit sugar consumption. This is based on the principle that cancer cells typically exhibit a higher metabolic rate and consume glucose (sugar) more rapidly than healthy cells to support their accelerated growth. This metabolic characteristic is effectively utilized in diagnostic tools such as PET-CT scans. During a PET-CT procedure, a small quantity of a radioactive glucose analog is administered. Cancer cells, due to their increased glucose uptake, absorb and retain this substance in much greater concentrations than normal cells, thereby enabling their precise detection and localization.
