Health Issue: Citamic C

Vitamin C can curb cancer growth, say researchers Wellington: Vitamin C can help curb the growth of cancer cells, according to New Zealand scientists who claim breakthrough research to provide the first real evidence of a connection between the vitamin and the development of tumours.         "Our results offer a promising and simple intervention to help in our fight against cancer at the level of both prevention and cure," Associate Professor Margreet Vissers, of the University of Otago's Free Radical Research Group, said.           She said the role of vitamin C in cancer treatment had been the subject of debate for years, with many anecdotal accounts of the vitamin's beneficial role. While her previous research had demonstrated the vitamin's importance in maintaning cell health and hinted at its potential for limiting diseases such as cancer, the latest sutdy looked at whether witamin C levels were lowered in patients with endometrial tumours.          She said the study found that tumours were less able to accumulate  vitamin C compared to normal tissue and this related to the ability of the tumour to survive and grow. "Tumours with low vitamin C levels had more of a prtein called HIF-1 which allows them to thrive in conditions of stress," she said, "The findings show a direct relationship between HIF-1 and vitamin C levels in tumours and suggest it would be beneficial for people with cancer cells to have more vitamin C."
