Liver metastasis of breast cancer is not the same thing as liver cancer. It refers to the metastasis of breast cancer cells to the liver, which usually requires treatment with appropriate drugs, which are different from chemotherapy drugs for liver cancer, and the surgical procedures for both are also different. If breast cancer is found to have metastasis to the liver, the metastatic cancer will not be removed and chemotherapy, targeted drug therapy, interventional therapy and other related treatments will be given. If liver cancer is found and the patient is in good health, liver cancer can be resected and other treatments will be given later. Patients should pay attention to their diet, such as not to drink alcoholic beverages and not to eat pickled food, which are likely to further increase the growth of tumor cells, and to consume fresh fruits and vegetables and high quality protein to improve the body’s resistance.
