People who smoke or have lung cancer should think twice about taking vitamin supplements, according to a Swedish study Wednesday that showed certain antioxidants may make tumors grow faster. In some preclinical studies, antioxidants have been found to promote tumor growth and metastasis in tumor-bearing mice and to increase the ability of circulating tumor cells to metastasize (29–31).

To directly address the role of ROS in cancer and potential antioxidant chemoprevention, we studied the effects of chronic administration of a nitroxide antioxidant, tempol (4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl), on longevity and tumor formation in tumor prone Atm-deficient mice, a model of the human cancer prone syndrome ataxia-telangiectasia (AT).

Interview with Prof Martin Bergö and Prof Per Lindahl, regarding a new study that shows that antioxidants accelerate lung cancer progression in mice. 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).

After administration of glycerol (a lung tumor promoter), lower induction of iNOS gene was observed in lung of the phytoene producing mice, comparing with that of control mice. Combinational use of various kinds of antioxidants distributed in foods, e.g., mixture of carotenoids and flavonoids, seems to be effective methods for cancer prevention.

Lung cancer is a leading type of cancer — and a leading killer — in the United States every year. The good news is many cases of lung cancer are believed to be preventable, as an estimated 90% of lung cancer cases are caused by active smoki If you have been diagnosed with adenocarcinoma cancer, you have a cancer that developed in one of the glands that lines the inside of your organs. Adenocarcinoma cancers being usually in one of the following organs: prostate, breast, colon, Lung cancer is a serious illness which none of us wish to face.

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.
