Intermediate stage invasive breast cancer is not as serious as advanced stage and can be cured with active treatment. Invasive breast cancer is one of the types of breast cancer, which indicates that the breast cancer tissues are detached from the basement membrane of the primary site and spread and metastasize to the distant tissues in the breast, but there is no distant metastasis and proliferation, which is relatively less serious, and there is a certain chance to be cured with active treatment. Generally speaking, patients with intermediate stage invasive breast cancer should prefer surgical treatment, through which tumor tissues and lymph nodes will be cleared, and radiotherapy, chemotherapy and targeted therapy will be carried out in the later stage, so that the cancer cells will be completely eliminated and thus cured, but whether they will be cured or not depends on their conditions and physical conditions.
