Whether ductal carcinoma of the breast can be cured depends on the stage of the disease. If it is early or middle stage breast cancer, the clinician’s aim of treatment is to cure it. If it is advanced breast cancer, the aim of treatment is to improve the patient’s quality of life and prolong the patient’s life as much as possible. If the patient’s life expectancy is not very long, and if there is no deterioration or progression of the disease during her lifetime, it can also be considered as a kind of cure. Therefore, whether breast cancer can be cured or not should be specifically analyzed according to different stages of the disease, different types of staging and the patient’s condition, and corresponding recommendations should be given.
