Breast cancer is a systemic disease, and usually after radical surgery, there is a need to increase nutrition after surgery, so post-operative recipes need to include as much high quality protein diet as possible, such as fish, eggs, protein powder, etc. However, excessive intake of estrogen is not recommended for breast cancer because estrogen may stimulate breast lumps or breast cancer development. Post-operative recipes also include fresh vegetables and fruits, and drinking more water is also useful. Breast cancer usually does not involve the digestive tract, and there are no special contraindications for other diets. A normal diet, increased nutrition and attention to eating less and more meals are fine, and it is not recommended to eat spicy and stimulating things that are not well digested, as well as smoked and barbecued things that may not be good for the digestion of the gastrointestinal tract and for the health of breast cancer patients.
