Breast cancer, also known as breast malignancy, is related to estrogen stimulation, so breast cancer patients should pay attention to their diet and try not to get involved with estrogen. What foods are related to estrogen? Foods with high fat content and high fat content have more estrogen because estrogen is usually found in fat cells. Also, foods with added estrogen or growth hormone, such as farmed seafood and farmed broilers, have added growth hormone, which can be converted into estrogen in the body, so try not to eat them. Nutritional products and health care products, such as gum, ganoderma lucidum spore powder and ginsenoside, often contain estrogen, so we should pay attention to this kind of diet and try to eat less. For breast cancer, we should try to eat vegetables, fruits and a light diet to reduce the intake of phytoestrogens. You should also eat less soy-based phytoestrogens, such as less soy milk and less soy beans.
