Invasive breast cancer is the most common type of breast cancer. If treated aggressively at an early stage, the cure rate of invasive breast cancer is relatively high, generally around 80%-90%, depending on the medical level of the hospital. Invasive breast cancer is a malignant tumor that originates from the ductal epithelium or glandular lobules of the breast. In the early stage, surgery can result in a good clinical cure because the lump itself is small and does not show signs of lymph node metastasis. In addition to active medical intervention, patients should also maintain a good mood and state of mind in daily life, as emotional factors can also affect the development of breast cancer to a certain extent. The diet should be regular and quantitative, avoid overeating and partial eating, eat less greasy, spicy, salted and smoked foods, and eat foods rich in high quality protein, such as milk, fish and eggs, to improve the body’s resistance to disease and correct the negative nitrogen balance.
