Resveratrol is a powerful antioxidant that can help prevent cell damage caused by free radicals. Damaged cells are more likely to become cancerous than healthy cells.  

Resveratrol has been proven to induce cancer cells to die in a preferable (i.e. normal) manner (like healthy cells die in their natural life cycle). Whereas radiation and chemotherapy cause cancer cells to break open and release their contents into the body, creating inflammation in neighboring cells, resveratrol induces white blood cells to consume the cellular debris of the cancer cell after its death (this process is called apoptosis).

Skin Cancer - Several studies have shown that Resveratrol applied to the skin of hairless mice before exposure to solar (UVB) radiation helped to prevent skin tumors. Interestingly, Resveratrol applied to the skin of hairless mice after exposure to solar (UVB) radiation produced the same results. Might resveratrol one day be used to prevent/treat skin cancer?
