There are generally no special contraindications to the diet of breast cancer patients, and they can eat mutton, but according to the patient’s own feelings. It is recommended to eat less of these meats and more fresh vegetables and fruits, which is good for health. In addition, you can properly supplement the high protein diet, such as fish, eggs, protein powder and so on are very good. However, foods that clearly contain relatively high levels of estrogen should be eaten as little as possible, as estrogen may lead to the development of breast cancer or further growth of breast lumps. Try not to eat animal ovaries and the like, as they also tend to raise blood fat, which is not good for your health. Breast cancer is usually treated by surgery, including mastectomy and axillary lymph node dissection, after which radiotherapy, chemotherapy, endocrine therapy and targeted drugs are also needed.
