Early stage breast malignant tumors may be curable; middle and late stage breast malignant tumors are less likely to be cured. Early-stage breast malignant tumors have not yet undergone distant metastasis and spread, at this time, the diseased tissues can be removed by means of surgical treatment in order to achieve the goal of curing the disease. In the middle and late stage, the breast malignant tumor has already developed distant metastasis and spread, and the lesion tissue can no longer be removed by surgical treatment alone, and some patients have even lost the chance of surgical treatment. The probability of cure in this case is relatively low. Patients with malignant breast tumors should go to the hospital as soon as possible to improve the chest CT, molybdenum target and other related examinations to clarify the severity of the disease. Clinicians will take into account the specific conditions of each patient to develop a personalized treatment plan.
