Tamoxifen: Tamoxifen is a drug that is used to treat women with breast cancer. It is also used to reduce the risk in women who are at a high risk of getting breast cancer. The drug acts like estrogen in the uterus. It can cause the uterine lining to grow and increase the risk of endometrial cancer. The risk of getting endometrial cancer in women taking tamoxifen is fairly small (about 1 in 500). It must be balanced against the value of this drug in treating and preventing breast cancer. This is something women may want to talk about with. | Nutrition Journal BioMed Central Review Open Access Nutrition and cancer A review of the evidence for an anti-cancer diet Michael S Donaldson Address Director of Research Hallelujah Acres Foundation 13553 Vantage Hwy Ellensburg WA 98926 USA Email Michael S Donaldson - michael@ Corresponding author Published 20 October 2004 Received 28 September 2004 Nutrition journal 2004 3 19 doi 1475-2891-3-19 Accepted 20 October 2004 This article is available from http content 3 1 19 2004 Donaldson licensee BioMed Central Ltd.

Abstract It has been estimated that 30-40 percent of all cancers can be prevented by lifestyle and dietary measures alone. Obesity nutrient sparse foods such as concentrated sugars and refined flour products that contribute to impaired glucose metabolism which leads to diabetes low fiber intake consumption of red meat and imbalance of omega 3 and omega 6 fats all contribute to excess cancer risk. Intake of flax seed especially its lignan fraction and abundant portions of fruits and vegetables will lower cancer risk. Allium and cruciferous vegetables are especially beneficial with broccoli sprouts being the densest source of sulforophane. Protective elements in a cancer prevention diet include selenium folic acid vitamin B-12 vitamin D chlorophyll and antioxidants such as the carotenoids a-carotene P-carotene lycopene lutein cryptoxanthin . Ascorbic acid has limited benefits orally but could be very beneficial intravenously. Supplementary use of oral digestive enzymes and probiotics also has merit as anticancer dietary measures. When a diet is compiled according to the guidelines here it is likely that there would be at least a 60-70 percent decrease in breast
