New evidence supports what Drs Linus Pauling and Matthius Rath knew almost 30 years ago. Vitamin C helps fight cancer. Their findings were originally dismissed by the medical community, but evidence continues to surface. For example, lung cancer patients have been found to have lower blood plasma concentrations of vitamin C (ascorbic acid) and also consume less vitamin C in their diets than do healthy individuals. Researchers at the University of Alabama now report that the vitamin C concentration in cancerous lung tissue is much higher than in adjacent healthy tissue. They believe the body tries to concentrate vitamin C in the diseased tissue in order to fight the cancer. The study involved 22 patients who had developed cancer (squamous cell carcinoma) of the lung or larynx. Most of the patients had been heavy smokers prior to surgery. The researchers measured the concentration of ascorbic acid in the cancerous and healthy tissue and found a marked difference. The amount of ascorbic acid in the cancerous tissue was approximately six times greater than that of healthy cells. Researchers conclude that the body’s natural defence mechanism concentrates vitamin C in cancerous lung tissue in order to increase deoxyribonucleic acid (DNA) methylation and thereby fight disease. They point out that other research has shown that breast cancer tumours also tend to have higher vitamin C levels than adjacent healthy tissue. The accumulation of ascorbic acid by squamous cell carcinomas of the lung and larynx is associated with global methylation of DNA. Source: Cancer, July 1, 2000
