Cancer cells have an Achilles heel, they can be starved to death

Concise summary of key highlights

In one line

Unlike normal cells, malignant or cancer cells are incapable of having a healthy metabolism and often look for substitute fuels and less efficient metabolic pathways to thrive.

Key points

• Metabolic instability in cancer

Cancer cells rely on inefficient metabolic pathways like fermentation due to their inability to use oxygen for energy, making them vulnerable to dietary interventions.

• Primary energy sources

Cancer cells depend heavily on glucose and glutamine for survival and growth, which can be removed to starve them.

• Mitochondrial role in cancer

Malfunctioning mitochondria in cancer cells spread metabolic dysfunction, driving cancer progression and spread.

• Biotin dependency

Cancer cells require Vitamin B7 (biotin) to bypass glutamine scarcity, and cutting biotin supply can stunt their growth.

• Metabolic theory of cancer

The Metabolic Theory of Cancer, supported by Warburg’s findings, redefines cancer as a metabolic disease, offering new treatment avenues.
