Invasive ductal breast carcinoma grade II is histologic grading, the prognosis needs to be combined with the staging, it is not possible to accurately determine the survival period, some patients have a 5-year survival rate of about 80%, and a 10-year survival rate of about 20% to 30%. Comprehensive judgment should also be made according to the specific situation. Invasive ductal carcinoma of breast grade II refers to moderately differentiated invasive ductal carcinoma, and its specific healing is related to the staging. If it is detected early and standardized treatment can be carried out at an early stage, most of them can usually be cured and the natural survival time is longer. If invasive ductal carcinoma of breast develops into middle or late stage, with recurrence and metastasis throughout the body, it becomes more difficult to treat, and at this time, the cure rate is very low, and the survival time will be greatly shortened. The treatment of advanced stage includes radiotherapy, chemotherapy, surgery and other comprehensive treatments, which are also more damaging to the body. If you are suffering from this kind of disease, please go to a regular hospital for treatment and regular review.
