The free radical scavenging effect of anthocyanins can also prevent cancer cells from spreading smoothly, thus protecting more healthy cells from being eroded by cancer cells. On the other hand, some cancers form tumors by dissolving substances from tissues and cells, and these cancer cells produce lysate and proteogens, while anthocyanins protect proteins from the effects of proteogens. For example, this is the pathogenic mechanism of breast cancer, so taking anthocyanins will have a good inhibitory effect on the development of breast cancer.
