Question: Are there vitamins or supplements that can reduce my risk of breast cancer? Do any increase cancer risk?
Answer: There is not enough evidence to support the use of a particular vitamin or supplement to reduce the risk of breast cancer. However, associations have been found between intake of certain foods and food-based nutrients, such as omega-3 fatty acids, extra virgin olive oil, vitamin C from foods, and others, and a reduced risk of breast cancer and/or breast cancer survivial. On the other hand, there is concern that certain foods, such as cow's milk, may increase the risk of breast cancer. Sign in to see the full answer >>
