Vitamin E Levels Drop Significantly, and DNA Damage Increases Dramatically in Lung Cancer Patients

Feb 07, 2005

  • 8-Oxodg is formed when free radicals oxidize and damage our DNA or when we are exposed to ionizing radiation. Increasing levels of 8-oxodg is connected with the cancer process.
  • The level of 8-oxodg and levels of vitamin C and vitamin E were checked in 4 groups: smokers with lung cancer, former smokers with lung cancer, healthy adults, and smokers free of lung cancer.
  • The levels of 8-oxodg were much higher in the DNA of both groups with lung cancer (smokers and ex-smokers)
  • Vitamin C levels were lower in both groups currently smoking (smokers with or smokers without lung cancer)
  • Vitamin E was significantly lower in both groups with lung cancer (smokers with and former smokers with lung cancer).
Low levels of vitamin E and high levels of DNA damage are connected to lung cancer. Additionally vitamin C is decreased in smokers with lung cancer and smokers without lung cancer. The study appears in the March 10th issue of the International Journal of Cancer.

Lycopene and Other carotenoids Decrease the Risk of Prostate Cancer

Patients with adenocarcinoma of the prostate were compared to hospitalized men who were free of prostate and all other cancers. Prostate cancer risk decreased with increasing consumption of lycopene, alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein and Zeaxanthin. High intake of tomatoes, pumpkin, spinach, watermelon, and citrus fruits also decreased the risk of prostate cancer. The study is published in the March 1st issue of the International Journal of Cancer.
