All cells need glucose (a form of sugar) for their metabolism. They get their glucose from circulating glucose, which is maintained in a safe range by the body’s sensors. The sugar you eat pushes up the circulating glucose, which is then brought back to normal by Insulin. No extra sugar reaches the cancer cell.
