The survival rate of patients with grade II invasive ductal carcinoma is about 80% for more than 5 years and 20%-30% for more than 10 years. Early detection, early diagnosis and early treatment are the keys to cure. The best treatment for invasive ductal carcinoma of the breast is early surgery. If early breast cancer can be detected, diagnosed and treated early, most of them can be cured. If early stage breast cancer can be detected, diagnosed and treated early, most of them can be cured. If it reaches the middle and late stage, with recurrence and metastasis throughout the body, it is more difficult to treat, and the cure rate is very low, and the survival time will be greatly shortened.
