Life expectancy after breast in situ cancer treatment cannot be generalized, but should be measured comprehensively according to clinical treatment plan, patient’s own physical condition, stage of disease development and other factors. At present, there is no accurate report on the survival rate of breast carcinoma in situ after cure, but for most patients, the survival rate can be improved through early detection, early diagnosis and early treatment. For patients with breast cancer in situ, early surgical resection can effectively prolong the survival of patients, and it is generally recommended to have a review every three months for two years after surgery, and every six months for three to five years after surgery. It is recommended that patients should go to the hospital in time for consultation and treatment under the guidance of physicians, so as to avoid delaying the condition.
