GlucoseCon, Glucose Consumption: Click to Expand ⟱
Source:
Type:
Glucose consumption is often elevated in cancer cells due to an increased reliance on glycolysis for energy production, even in the presence of oxygen. This phenomenon, known as the Warburg effect, is a metabolic shift that allows cancer cells to rapidly proliferate and survive in nutrient-poor environments.

The increased glucose consumption in cancer cells can be detected using positron emission tomography (PET) scans, which measure the uptake of a glucose analog labeled with a radioactive tracer.
