Bitter melon has no inhibitory effect on liver cancer, and no food can replace medicine for treatment. The cause of liver cancer is still unclear, but it is not excluded that it has direct relationship with hepatitis virus, aflatoxin, drug factors and cirrhosis. These factors will affect the damage and repair of human liver cells, oncogenes and proto-oncogenes accordingly. Although relevant studies have shown that some active ingredients in bitter melon, such as bitter melon polysaccharides, bitter melon saponins, bitter melon elements and other related components can indeed inhibit the growth of cancer cells in vitro cellular experiments, but these components are not useful in human beings, or play a very small role. The extracts of certain components of bitter melon used in the experimental process have higher concentrations, which may be able to achieve a certain effect. However, in the real bitter melon, these ingredients are often lower, so no food can replace the medicine for treatment. If a patient is clearly suffering from liver cancer, he or she should be treated in a scientific way so as not to delay his or her condition.
