Encapsulated papillary carcinoma can be treated by surgery together with chemotherapy and endocrine drugs. Encapsulated papillary carcinoma, also called breast encapsulated papillary carcinoma, is a kind of invasive tumor, and in the early stage of the disease, patients can be treated by surgery. If patients want to keep part of their breasts, they can adopt partial excision surgery and extended excision surgery, which should be combined with chemotherapy after surgery, and the commonly used drugs include Adriamycin and Zoerythromycin and so on. If patients have no requirement for breast preservation, they can choose total excision surgery for treatment. Since breast encapsulated papillary carcinoma is a specific tumor, which is one of the low-risk tumors, it can be treated without chemotherapy after total excision surgery, but it needs to be treated with endocrine drugs, such as tamoxifen, letrozole and so on. When a patient is diagnosed with breast encapsulated papillary carcinoma, it is important to have timely treatment to avoid spreading.
