It seems that antioxidants are able to I) decrease the cancer formation risk by quenching ROS that are involved in cancer initiation and progression and II) assist in survival of cancer/precancer cells once the malignant transformation already A study by Swedish researchers reported recently in Science Translational Medicine shows that two antioxidants— N -acetylcysteine and vitamin E—accelerate the progression of early lung tumors in mice and in human lung cancer cell lines. Antioxidant supplements that are supposed to boost health and slow ageing could in fact spur the spread of melanoma, the deadliest type of skin cancer, researchers say.

The fin The work, conducted in mice, shows that antioxidants can change cells in ways that fuel the spread of malignant melanoma—the most serious skin cancer—to different parts of the body. The progression Using male Lady transgenic mice, we show that administration of antioxidants (vitamin E, selenium, and lycopene) in the diet at a human achievable dose significantly inhibits prostate cancer development and increases the disease-free survival of these mice. mice with B-RAF– and K-RAS–induced lung cancer by reducing ROS, DNA damage, and p53 ( 7). These results suggest that lung tumor cells proliferate faster when the amounts of ROS are low, and this may be accomplished by dietary antioxidants or by mutations that activate an endogenous ROS defense system coordinated by NRF2/KEAP1 ( 8).
