Do cancer cells thrive on sugar?

As an expert in the field of oncology, I can provide some insights into the relationship between cancer cells and sugar. It is a common misconception that cancer cells thrive on sugar or that consuming sugar directly feeds and accelerates the growth of cancer. While it is true that all cells, including cancer cells, require glucose for energy, the idea that sugar consumption directly fuels cancer growth is not supported by scientific evidence. Cancer cells do have a higher rate of glycolysis, a process where glucose is broken down to produce energy, even in the presence of oxygen. This phenomenon is known as the Warburg effect. However, this does not mean that consuming more sugar will make cancer worse. The body's cells, including cancer cells, will use the glucose that is available in the bloodstream, which comes from all carbohydrates, not just sugar. It is important for individuals with cancer to maintain a healthy diet, but there is no need to eliminate sugar entirely from the diet. Instead, focusing on a balanced diet with a variety of nutrients is recommended.

Myth: People with cancer shouldn't eat sugar, since it can cause cancer to grow faster. ... All cells, including cancer cells, depend on blood sugar (glucose) for energy. But giving more sugar to cancer cells doesn't speed their growth.
